Add reconcileAggregatedAPIServicesAvailableCondition which lists all expected aggregated APIServices in the guest cluster and sets the AggregatedAPIServicesAvailable condition on the HostedControlPlane. Extract patchHCPWithCondition from inline closure to a shared method on the reconciler for reuse across condition reconcilers.

15:37:32 +0000 Subject: [PATCH 5/8] fix(operator): address review feedback and fix verify Apply optimistic locking in patchHCPWithCondition using MergeFromWithOptions with OptimisticLock to match the codebase convention used throughout the HCP controller, preventing lost status-condition updates from concurrent reconcilers. Fix test case name from "condition is missing" to "condition is False" to accurately reflect the test setup which sets AggregatedAPIServicesAvailable=False. Include generated API docs for the new AggregatedAPIServicesAvailable condition type to fix make verify.

If the management cluster's VNet uses `10.0.0.0/16`, the NAT subnet must - fall within that range (e.g., `10.0.64.0/24`) or you must first expand the VNet's - address space. - -Get the NAT subnet resource ID for later use: - -```bash -NAT_SUBNET_ID=$(az network vnet subnet show \ - --resource-group "${MGMT_VNET_RG}" \ - --vnet-name "${MGMT_VNET_NAME}" \ - --name "${NAT_SUBNET_NAME}" \ - --query id -o tsv) -``` - -!!! important - - The NAT subnet **must** be in the management cluster's VNet, not the guest VNet. - This is because the Private Link Service is created alongside the management - cluster's internal load balancer. - -!!! note - - The `--disable-private-link-service-network-policies true` flag is required. - Without it, Azure will reject PLS creation on this subnet. - -## Step 2: Install HyperShift Operator with Private Platform Support - -To support private clusters, the HyperShift operator must be installed with -additional flags that configure Azure Private Link Service management. - -You need credentials that allow the operator to manage PLS resources: - -```bash -# Azure credentials file for PLS management (same format as standard Azure creds) -AZURE_PRIVATE_CREDS="/path/to/azure-private-credentials.json" - -# Management cluster's infrastructure resource group -MGMT_INFRA_RG=$(oc get infrastructure cluster -o jsonpath='{.status.platformStatus.azure.resourceGroupName}') -``` - -Install the operator with private platform support. The private-specific flags are -added **in addition to** the standard install flags (External DNS, pull secret, etc.): - -```bash -hypershift install \ - --pull-secret ${PULL_SECRET} \ - --private-platform Azure \ - --azure-private-creds ${AZURE_PRIVATE_CREDS} \ - --azure-pls-resource-group ${MGMT_INFRA_RG} \ - # ... include your standard install flags (External DNS, etc.) -``` - -| Flag | Description | -|------|-------------| -| `--private-platform Azure` | Enables Azure Private Link Service management in the operator | -| `--azure-private-creds` | Path to Azure credentials file used for PLS operations | -| `--azure-pls-resource-group` | Resource group where PLS resources will be created (the management cluster's infrastructure RG) | - -**Alternative authentication methods** (use one of these instead of `--azure-private-creds`): - -| Flag | Description | -|------|-------------| -| `--azure-private-secret` | Name of an existing Kubernetes secret containing Azure credentials (use with `--azure-private-secret-key` to specify the key, default: `credentials`) | -| `--azure-pls-managed-identity-client-id` | Client ID of a managed identity for PLS operations via Azure Workload Identity federation (requires `--azure-pls-subscription-id`) | -| `--azure-pls-subscription-id` | Azure subscription ID for PLS operations (required with `--azure-pls-managed-identity-client-id`) | - -!!! warning "Choose One Authentication Method" - - The three authentication methods (`--azure-private-creds`, `--azure-private-secret`, - `--azure-pls-managed-identity-client-id`) are **mutually exclusive**.

The operator will not watch `AzurePrivateLinkService` CRs until - configured with private platform support. You can safely re-run `hypershift install` - to update the existing installation. - -## Step 3: Create IAM Resources - -Create workload identities for the cluster. The `create iam azure` command always creates -a Control Plane Operator identity, which is used by private clusters to manage Private -Endpoints and Private DNS zones in the guest subscription. - -```bash -PREFIX="your-prefix" -CLUSTER_NAME="${PREFIX}-hc" -RESOURCE_GROUP_NAME="${CLUSTER_NAME}-${PREFIX}" -LOCATION="eastus" -AZURE_CREDS="/path/to/azure-credentials.json" -OIDC_ISSUER_URL="https://yourstorageaccount.blob.core.windows.net/yourstorageaccount" -WORKLOAD_IDENTITIES_FILE="./workload-identities.json" - -hypershift create iam azure \ - --name "${CLUSTER_NAME}" \ - --infra-id "${PREFIX}" \ - --azure-creds "${AZURE_CREDS}" \ - --location "${LOCATION}" \ - --resource-group-name "${RESOURCE_GROUP_NAME}" \ - --oidc-issuer-url "${OIDC_ISSUER_URL}" \ - --output-file "${WORKLOAD_IDENTITIES_FILE}" -``` - -The command creates 8 workload identities, including the Control Plane Operator identity: - -| Identity | Operator | Azure Role | Scopes | -|----------|----------|------------|--------| -| **Control Plane Operator** | CPO | Contributor (default) or Custom HCP Role | Managed RG, NSG RG, VNet RG | - -This identity allows the CPO to create and manage Private Endpoints, Private DNS zones, -VNet links, and DNS A records in the guest subscription. - -!!! note - - The CPO identity is assigned the **Contributor** role by default. When using - `--assign-custom-hcp-roles`, a more restrictive custom role is used instead. - -## Step 4: Create Infrastructure - -Create the Azure infrastructure. The `create infra azure` command creates the same -resources regardless of endpoint access topology: - -```bash -DNS_ZONE_RG_NAME="os4-common" -PARENT_DNS_ZONE="your-base.domain.com" -INFRA_OUTPUT_FILE="${PREFIX}-infra-output.json" - -hypershift create infra azure \ - --azure-creds "${AZURE_CREDS}" \ - --infra-id "${PREFIX}" \ - --name "${CLUSTER_NAME}" \ - --location "${LOCATION}" \ - --base-domain "${PARENT_DNS_ZONE}" \ - --dns-zone-rg-name "${DNS_ZONE_RG_NAME}" \ - --workload-identities-file "${WORKLOAD_IDENTITIES_FILE}" \ - --assign-identity-roles \ - --output-file "${INFRA_OUTPUT_FILE}" -``` - -## Step 5: Create the Private HostedCluster - -Read the infrastructure output to get the resource IDs created in Step 4: - -```bash -MANAGED_RG_NAME=$(yq -r -p yaml '.resourceGroupName' "${INFRA_OUTPUT_FILE}") -VNET_ID=$(yq -r -p yaml '.vnetID' "${INFRA_OUTPUT_FILE}") -SUBNET_ID=$(yq -r -p yaml '.subnetID' "${INFRA_OUTPUT_FILE}") -NSG_ID=$(yq -r -p yaml '.securityGroupID' "${INFRA_OUTPUT_FILE}") -``` - -Create the private HostedCluster: - -```bash -hypershift create cluster azure \ - --name "$CLUSTER_NAME" \ - --namespace "clusters" \ - --azure-creds ${AZURE_CREDS} \ - --location ${LOCATION} \ - --node-pool-replicas 2 \ - --base-domain ${PARENT_DNS_ZONE} \ - --pull-secret ${PULL_SECRET} \ - --generate-ssh \ - --release-image ${RELEASE_IMAGE} \ - --resource-group-name "${MANAGED_RG_NAME}" \ - --vnet-id "${VNET_ID}" \ - --subnet-id "${SUBNET_ID}" \ - --network-security-group-id "${NSG_ID}" \ - --sa-token-issuer-private-key-path "${SA_TOKEN_ISSUER_PRIVATE_KEY_PATH}" \ - --oidc-issuer-url "${OIDC_ISSUER_URL}" \ - --dns-zone-rg-name ${DNS_ZONE_RG_NAME} \ - --assign-service-principal-roles \ - --workload-identities-file ${WORKLOAD_IDENTITIES_FILE} \ - --diagnostics-storage-account-type Managed \ - --external-dns-domain ${DNS_ZONE_NAME} \ - --endpoint-access Private \ - --endpoint-access-private-nat-subnet-id "${NAT_SUBNET_ID}" -``` - -!!! note - - The `--endpoint-access` flag accepts three values: - - - `Public` (default): API server accessible via public endpoint only - - `PublicAndPrivate`: API server accessible via both public and private endpoints - - `Private`: API server accessible only via Private Link (private endpoint) - -!!! warning "Endpoint Access Type is Immutable" - - You **cannot** change a cluster between `Public` and non-Public (`Private` or - `PublicAndPrivate`) after creation.

Without it, the restore will fail and nodes will be unable to rejoin the cluster. - -### Why Is This Required? - -When a HostedCluster is restored on a different Management cluster: - -- The infrastructure endpoints (e.g., Load Balancer addresses, Route URLs) change because they are ephemeral and tied to the original Management cluster. -- Nodes store the KAS (Kube API Server) address in their kubelet configuration. If that address was an ephemeral Load Balancer or Route URL, nodes will point to the old address after restore. -- TLS certificates (SAN - Subject Alternative Name) will not match the new ephemeral endpoints, causing certificate validation failures. -- A fixed hostname configured via DNS allows you to update the DNS record to point to the new Management cluster's endpoint, making the migration transparent for existing nodes. - -### Minimum Required Configuration - -At a minimum, the **APIServer** service must have a fixed hostname: - -```yaml -spec: - services: - - service: APIServer - servicePublishingStrategy: - type: LoadBalancer - loadBalancer: - hostname: api-int.example.com -``` - -### Recommended Production Configuration - -For production environments, it is strongly recommended to configure **all** services with fixed hostnames: - -```yaml -spec: - services: - - service: APIServer - servicePublishingStrategy: - type: LoadBalancer - loadBalancer: - hostname: api-int.example.com - - service: OAuthServer - servicePublishingStrategy: - type: Route - route: - hostname: oauth.example.com - - service: OIDC - servicePublishingStrategy: - type: Route - route: - hostname: oidc.example.com - - service: Konnectivity - servicePublishingStrategy: - type: Route - route: - hostname: konnectivity.example.com - - service: Ignition - servicePublishingStrategy: - type: Route - route: - hostname: ignition.example.com -``` - -This ensures full service continuity and DNS consistency during the restore process on a different Management cluster. - -### AWS Self-Managed Platform Specifics - -When using AWS platform with self-managed infrastructure, the APIServer can also use a **Route** service publishing strategy with a fixed hostname: - -```yaml -spec: - platform: - aws: - endpointAccess: Public - services: - - service: APIServer - servicePublishingStrategy: - type: Route - route: - hostname: api.example.com -``` - -## Platform-Specific Prerequisites - -### Bare Metal / Agent Provider - -!!! note "InfraEnv Lifecycle" - - Since the InfraEnv has a different lifecycle than the HostedCluster, it should reside in a namespace separate from that of the HostedControlPlane and must not be deleted during backup or restore procedures. - -### AWS Provider - -- Ensure OIDC provider configuration is accessible for post-restore fixup (see Fixing OIDC After Restore). -- If using S3 for backup storage, ensure IAM roles and policies are configured following the official documentation. - -## Fixing OIDC After Restore - -After completing an OADP restore on AWS, if the control-plane-operator reports `WebIdentityErr` errors or NodePool nodes remain not-ready due to a missing default security group, run the OIDC disaster recovery command: - -```bash -hypershift fix dr-oidc-iam \ - --hc-name \ - --hc-namespace \ - --aws-creds ~/.aws/credentials -``` - -This re-uploads the OIDC discovery documents using the existing cluster signing key and recreates the IAM OIDC provider if needed.

In HCP, the architecture is fundamentally different: the KAS runs as pods on the **management cluster**, while SPO runs on the **hosted (guest) cluster**. - -!!! warning "Key Architectural Difference" - The KAS audit logs are **not accessible from the guest cluster**. The KAS pods reside in the HostedControlPlane namespace on the management cluster, and there is no direct path from the guest cluster's data plane to those logs. SPO, running on the guest cluster, cannot natively read the KAS audit logs the way it does on a standard OCP cluster. - -### Viewing Audit Logs from the Management Cluster - -An administrator with access to the management cluster can view the audit logs directly: - -```bash -oc get pods -n -l app=kube-apiserver -``` - -```bash -oc logs -n -c kube-apiserver | grep audit -``` - -!!! note - The `` is typically `-` on the management cluster. - -### Making Audit Logs Available to SPO - -Since SPO on the guest cluster cannot directly access the KAS audit logs on the management cluster, you need to establish a mechanism to forward or expose those logs. Some approaches to consider: - -- **Log forwarding via ClusterLogForwarder**: Configure log forwarding on the management cluster to send KAS audit logs to a centralized logging backend (e.g., Elasticsearch, Loki, Splunk). SPO and security teams can then consume audit data from the shared logging infrastructure. -- **Audit Log Persistence with external access**: Enable the Audit Log Persistence feature to store audit logs in PersistentVolumes on the management cluster, then export or sync them to a location accessible to the guest cluster or to your security tooling. -- **Audit webhook backend**: Configure the KAS audit webhook backend to send audit events to an external endpoint that SPO or your security infrastructure can consume. This can be configured via the HostedCluster's `spec.configuration.apiServer.audit` settings. - -!!! tip - The specific approach depends on your organization's logging architecture and security requirements. In all cases, the audit logs must be forwarded or exported from the management cluster since the guest cluster has no direct access to the KAS pods. - -## Step 3: Configure Worker Nodes for Seccomp Logging - -SPO requires CRI-O configuration on worker nodes to enable the `--privileged-seccomp-profile` or seccomp log mode.

The controller also computes the full `noProxy` list automatically, adding the cluster, service, and machine network CIDRs, cloud metadata endpoints (e.g. `169.254.169.254` for AWS and Azure), and internal compute domains. - -- **`image`** — image registry policies (`allowedRegistriesForImport`, `externalRegistryHostnames`, `additionalTrustedCA`, `registrySources`). Although this configuration is served directly by the ignition server rather than embedded in the node user-data, a change still triggers a rollout so Nodes pick up the new configuration. - -!!! note - - Other fields inside `HostedCluster.spec.configuration` such as `oauth`, `apiServer`, `authentication`, `scheduler`, or `ingress` do **not** trigger a NodePool rollout. They are reconciled through other control plane mechanisms. - -### Platform-Specific Machine Template - -Changes to platform-specific infrastructure fields produce a new machine template, which triggers a rollout.

Changing tags alone does not cause Nodes to be replaced. - -**Other platforms (Azure, KubeVirt, OpenStack, Agent, PowerVS):** - -Any change to the platform-specific machine template spec triggers a rollout. Refer to the API reference for the full list of fields per platform. - -## What Does Not Trigger a Rollout - -The following fields are propagated in-place to existing Nodes without triggering a rollout: - -| Field | Behavior | -|-------|----------| -| `spec.nodeLabels` | Propagated directly to existing Machine objects | -| `spec.taints` | Propagated directly to existing Machine objects | -| `spec.replicas` / `spec.autoScaling` | Only changes the number of Nodes, no replacement | -| `spec.nodeDrainTimeout` | Updated on existing Machines without replacement | -| `spec.nodeVolumeDetachTimeout` | Updated on existing Machines without replacement | -| `spec.management.replace.rollingUpdate` | Changes rollout parameters (maxSurge, maxUnavailable) but does not itself cause a rollout | -| `spec.management.autoRepair` | Toggles MachineHealthCheck without replacing Nodes | - -## Upgrade Types - -The upgrade type determines **how** Nodes are replaced or updated during a rollout. It is set once at NodePool creation and **cannot be changed** afterward. - -### Replace - -Replace upgrades create new Node instances with the updated configuration and remove old ones. This is the default and recommended approach for cloud environments where creating and destroying instances is cost-effective. - -The replacement process is governed by the `spec.management.replace` field: - -#### RollingUpdate Strategy (default) - -New Nodes are created before old Nodes are removed, ensuring workload availability during the rollout. - -| Parameter | Default | Description | -|-----------|---------|-------------| -| `maxSurge` | `1` | Maximum number of Nodes that can be provisioned above the desired count during the rollout. Can be an absolute number or a percentage. | -| `maxUnavailable` | `0` | Maximum number of Nodes that can be unavailable during the rollout. Can be an absolute number or a percentage. | - -With the defaults (`maxSurge=1`, `maxUnavailable=0`), one new Node is created at a time, and old Nodes are only removed after the new Node is ready. This is the safest configuration but also the slowest. - -To speed up the rollout, you can increase `maxSurge` (more Nodes created in parallel) or increase `maxUnavailable` (allow removing old Nodes before new ones are ready), at the cost of reduced capacity during the rollout. - -!!! important - - `maxSurge` and `maxUnavailable` cannot both be `0`. - -#### OnDelete Strategy - -Old Nodes are only replaced when they are manually deleted. This gives you full control over the rollout pace and order. Once an old Node is deleted, a new Node with the updated configuration is created to replace it. - -### InPlace - -InPlace upgrades update the operating system of existing Node instances without creating new ones. This is the recommended approach for environments with high infrastructure constraints, such as bare metal. - -| Parameter | Default | Description | -|-----------|---------|-------------| -| `maxUnavailable` | `1` | Maximum number of Nodes that can be unavailable during the in-place update. Can be an absolute number or a percentage. The minimum enforced value is `1`. | - -!!! important - - When using InPlace upgrades, platform-specific machine template changes (e.g. instance type, AMI) will **only apply to new Nodes** that are created after the change. Existing Nodes are not affected by platform changes. - -## Rollout Lifecycle - -When a rollout is triggered, the controller follows this sequence: - -1. **Change detection** — the controller compares the desired state (from the NodePool and HostedCluster specs) against the current state tracked in the NodePool status and annotations. - -2. **New configuration artifacts** — a new ignition token Secret and user-data Secret are generated with names derived from a hash of the new configuration. The previous token is marked as expired. - -3. **New machine template** (if platform fields changed) — a new platform-specific machine template is created. Its name includes a hash of the spec, so any change produces a distinct template. - -4. **Rollout execution**: - - **Replace:** the MachineDeployment is updated with the new user-data Secret, machine template, and version references. CAPI orchestrates Node creation and deletion according to the configured strategy (RollingUpdate or OnDelete). - - **InPlace:** the MachineSet is updated with the new target configuration. An in-place upgrader applies the changes to existing Nodes, respecting `maxUnavailable`. - -5. **Completion** — the rollout is considered complete when: - - **Replace:** all desired replicas are updated and available. - - **InPlace:** all Nodes report the target configuration version. - -6. **Status update** — `NodePool.status.version` is updated and the internal tracking annotations are set to the new values. - -### Monitoring Rollout Progress - -You can monitor rollout progress through the following NodePool conditions: - -| Condition | Meaning | -|-----------|---------| -| `UpdatingVersion` | A version rollout is in progress | -| `UpdatingConfig` | A configuration rollout is in progress | -| `UpdatingPlatformMachineTemplate` | A platform machine template rollout is in progress | - -These conditions are set to `True` while the corresponding rollout is in progress and are cleared when it completes. - -## Summary Table - -| Change | Triggers Rollout | Affects | -|--------|:---:|---------| -| `NodePool.spec.release.image` | Yes | The changed NodePool | -| `NodePool.spec.config` | Yes | The changed NodePool | -| `NodePool.spec.tuningConfig` | Yes | The changed NodePool | -| `HostedCluster.spec.pullSecret` (name change) | Yes | All NodePools | -| `HostedCluster.spec.additionalTrustBundle` (name change) | Yes | All NodePools | -| `HostedCluster.spec.imageContentSources` | Yes | All NodePools | -| `HostedCluster.spec.configuration.proxy` | Yes | All NodePools | -| `HostedCluster.spec.configuration.image` | Yes | All NodePools | -| Platform machine template fields | Yes | The changed NodePool | -| `NodePool.spec.nodeLabels` | No | Propagated in-place | -| `NodePool.spec.taints` | No | Propagated in-place | -| `NodePool.spec.replicas` / `autoScaling` | No | Scale only | -| `NodePool.spec.nodeDrainTimeout` | No | Propagated in-place | -| `NodePool.spec.management.autoRepair` | No | MachineHealthCheck toggle | -| AWS `spec.platform.aws.resourceTags` | No | Applied without rollout | - - --- ## Source: docs/content/reference/ocp-behaviour-deviations/index.md @@ -53080,1268 +49340,6 @@ HyperShift allows customers to just leave their NodePools on 4.17, while creatin - In the worst case, you can report the issue as a bug to the team for the further investigation. ---- - -## Source: docs/content/reference/service-publishing-strategies.md - -# Service Publishing Strategy Reference - -Service publishing strategies control how control plane services are exposed to external users and the data plane. - -## Overview - -### Services - -HostedClusters expose the following control plane services: - -- **APIServer**: The Kubernetes API server endpoint -- **OAuthServer**: The OAuth authentication service -- **Konnectivity**: The networking proxy service for control plane to data plane communication -- **Ignition**: The node ignition configuration service - -### Publishing Strategy Types - -Each service can be published using one of the following strategies: - -| Strategy Type | Description | Use Case | -|--------------|-------------|----------| -| **LoadBalancer** | Exposes the service through a dedicated cloud load balancer | Primary method for exposing KubeAPIServer in cloud environments without external DNS configured | -| **Route** | Exposes the service through OpenShift Routes and the management cluster's ingress controller | Default for most services; requires management cluster to have Route capability | -| **NodePort** | Exposes the service on a static port on each node | Used in on-premise and bare metal scenarios (Agent, None platforms) | - -### Terminology - -Understanding the following terms is essential for configuring service publishing strategies: - -| Term | Definition | -|------|------------| -| **Public** | Services accessible from the public internet. Uses external-facing load balancers or publicly accessible routes. | -| **Private** | Services accessible only through private networking (e.g., AWS PrivateLink, GCP Private Service Connect). Not accessible from the public internet. | -| **PublicAndPrivate** | Services accessible from both the public internet AND through private networking within the VPC. On AWS, this means endpoints are reachable externally and via PrivateLink. On GCP, this means endpoints are reachable externally and via Private Service Connect. | -| **External** | Refers to resources or endpoints accessible from outside the management cluster's VPC or network. Typically synonymous with "public" but may also include cross-VPC access. | -| **Internal** | Refers to resources or endpoints accessible only within the management cluster's VPC or network. Uses internal load balancers or private networking. | -| **External DNS** | A system that manages DNS records in a public or shared DNS zone. The `--external-dns-domain` flag enables this functionality, allowing custom hostnames for services. | -| **External Load Balancer** | A cloud load balancer with a public IP address, accessible from the internet. | -| **Internal Load Balancer** | A cloud load balancer with a private IP address, accessible only within the VPC or through private networking (e.g., PrivateLink). | -| **HCP Router** | A dedicated router (typically HAProxy or OpenShift Router) deployed within the Hosted Control Plane namespace, scoped to a specific hosted cluster. Used when Route publishing strategy is configured with external DNS. | -| **Management Cluster Ingress** | The shared ingress controller of the management cluster (e.g., OpenShift Router). Used for Route publishing when external DNS is not configured. | - -### Configuration Requirements - -1. **Unique Hostnames**: Each service must have a unique hostname if a hostname is specified in the publishing strategy -2. **Route Publishing**: Services using the `Route` publishing strategy can be exposed either through the management cluster's ingress controller (requires OpenShift) or through HyperShift's dedicated HCP router (a router deployed in the hosted control plane namespace, scoped to the specific hosted cluster, which works on any Kubernetes cluster) - -## Platform-Specific Configurations - -### AWS - -AWS publishing strategies are determined by the endpoint access mode and whether external DNS is configured. - -#### Endpoint Access Types - -AWS HostedClusters support three endpoint access modes that control how the API server and other control plane services are exposed: - -| Access Type | Description | -|------------|-------------| -| **Public** | Control plane endpoints are accessible from the public internet. External users and data plane nodes connect via public load balancers or routes. | -| **PublicAndPrivate** | Control plane endpoints are accessible from both the public internet AND from within the VPC via AWS PrivateLink. Provides flexibility for both external access and private VPC connectivity. | -| **Private** | Control plane endpoints are only accessible from within the VPC via AWS PrivateLink. No public internet access. External users must connect through VPN or other private connectivity solutions. | - -The endpoint access type is specified in `spec.platform.aws.endpointAccess` and affects which service publishing strategies are valid and how services are exposed. - -#### Public Endpoint Access - -**With External DNS** (`--external-dns-domain` flag): - -- **APIServer**: `Route` (hostname required) -- **OAuthServer**: `Route` (hostname required) -- **Konnectivity**: `Route` (hostname required) -- **Ignition**: `Route` (hostname required) - -All Route-based services are exposed through a dedicated HCP router with an external load balancer. - -**Example Configuration:** - -```yaml -spec: - platform: - type: AWS - aws: - endpointAccess: Public - services: - - service: APIServer - servicePublishingStrategy: - type: Route - route: - hostname: api.my-cluster.example.com - - service: OAuthServer - servicePublishingStrategy: - type: Route - route: - hostname: oauth.my-cluster.example.com - - service: Konnectivity - servicePublishingStrategy: - type: Route - route: - hostname: konnectivity.my-cluster.example.com - - service: Ignition - servicePublishingStrategy: - type: Route - route: - hostname: ignition.my-cluster.example.com -``` - -```mermaid -graph RL - subgraph "Management Cluster" - subgraph HCP ["Hosted Control Plane"] - KAS[APIServer] - OAuth[OAuthServer] - Konnectivity[Konnectivity] - Ignition[Ignition] - Router[HCP Router

The architecture separates traffic into two paths: - -1. **External Traffic (KAS, OAuth)**: Flows through a **Shared Ingress HAProxy** deployment. A single HAProxy in the `hypershift-sharedingress` namespace, fronted by one Azure LoadBalancer, routes traffic to the correct hosted control plane using SNI-based hostname routing. - -2. **In-Cluster Traffic (Konnectivity, Ignition)**: Flows through **Swift** (Azure Service Networking). Private router pods are labeled with `kubernetes.azure.com/pod-network-instance`, which connects them directly to the customer VNet. Services resolve via the `hypershift.local` internal DNS zone (e.g., `konnectivity-server.apps..hypershift.local`). - -**Architecture Diagram:** - -```mermaid -graph RL - subgraph "AKS Management Cluster" - subgraph SharedIngress ["Shared Ingress (hypershift-sharedingress namespace)"] - HAProxy[Central HAProxy

Note that Managed GCP requires external DNS, while it's optional for AWS, Azure, and KubeVirt. - -2. **Understand endpoint access modes**: On AWS, choose the endpoint access mode that matches your security requirements: - - `Public`: Services accessible from the internet - - `PublicAndPrivate`: Services accessible from both internet and VPC - - `Private`: Services only accessible from VPC - -3. **Validate your configuration**: Always check the `ValidConfiguration` condition on your HostedCluster to ensure your service publishing strategy is valid: - ```bash - oc get hostedcluster -o jsonpath='{.status.conditions[?(@.type=="ValidConfiguration")]}' - ``` - -4. **Consider management cluster capabilities**: Ensure your management cluster has Route capability (i.e., is an OpenShift cluster) if you plan to use Route-based publishing strategies. - -5. **Use LoadBalancer for Agent platform in production**: For Agent platform deployments (bare metal and non-bare-metal), use the LoadBalancer publishing strategy for production environments. NodePort is the default because Agent platform environments may not have a load balancer provider available out of the box (e.g., bare metal clusters without MetalLB), but LoadBalancer provides better certificate handling, automatic DNS resolution, and simplified access when available. - -6. **Plan for high availability**: When using NodePort strategies, remember that you're pointing to specific node IPs. Consider using a load balancer or DNS round-robin for high availability. - -## Troubleshooting - -### ValidConfiguration Condition is False - -If the `ValidConfiguration` condition is set to `False`, check the condition message for details. Common issues include: - -- Using an unsupported publishing strategy for a specific service on your platform -- Missing required hostname for Route-based APIServer publishing -- Using LoadBalancer for APIServer when external DNS is configured -- Duplicate hostnames across services - -### Management Cluster Doesn't Support Routes - -If you see an error about Routes not being supported, this means your management cluster is not an OpenShift cluster. You'll need to either: - -- Use a different publishing strategy (e.g., LoadBalancer or NodePort) -- Deploy your HostedCluster on an OpenShift management cluster - -### Service Not Accessible - -If a service is configured but not accessible: - -1. Verify the service publishing strategy is valid for your platform -2. Check that the management cluster has the necessary capabilities -3. Verify DNS resolution for Route-based services -4.

release specifies the desired OCP release payload for all the hosted cluster components. +This includes those components running management side like the Kube API Server and the CVO but also the operands which land in the hosted cluster data plane like the ingress controller, ovn agents, etc. +The maximum and minimum supported release versions are determined by the running Hypersfhit Operator. +Attempting to use an unsupported version will result in the HostedCluster being degraded and the validateReleaseImage condition being false. +Attempting to use a release with a skew against a NodePool release bigger than N-2 for the y-stream will result in leaving the NodePool in an unsupported state. +Changing this field will trigger a rollout of the control plane components. +The behavior of the rollout will be driven by the ControllerAvailabilityPolicy and InfrastructureAvailabilityPolicy for PDBs and maxUnavailable and surce policies.

+
+controlPlaneRelease
+ + +Release + + +		 +(Optional) +

controlPlaneRelease is like spec.release but only for the components running on the management cluster. +This excludes any operand which will land in the hosted cluster data plane. +It is useful when you need to apply patch management side like a CVE, transparently for the hosted cluster. +Version input for this field is free, no validation is performed against spec.release or maximum and minimum is performed. +If defined, it will dicate the version of the components running management side, while spec.release will dictate the version of the components landing in the hosted cluster data plane. +If not defined, spec.release is used for both. +Changing this field will trigger a rollout of the control plane. +The behavior of the rollout will be driven by the ControllerAvailabilityPolicy and InfrastructureAvailabilityPolicy for PDBs and maxUnavailable and surce policies.

kubeAPIServerDNSName specifies a desired DNS name to resolve to the KAS. +When set, the controller will automatically generate a secret with kubeconfig and expose it in the hostedCluster Status.customKubeconfig field. +If it’s set or removed day 2, the kubeconfig generated secret will be created, recreated or deleted. +The DNS entries should be resolvable from the cluster, so this should be manually configured in the DNS provider. +This field works in conjunction with configuration.APIServer.ServingCerts.NamedCertificates to enable +access to the API server via a custom domain name. The NamedCertificates provide the TLS certificates +for the custom domain, while this field triggers the generation of a kubeconfig that uses those certificates. +This API endpoint only works in OCP version 4.19 or later. Older versions will result in a no-op.

+
+controllerAvailabilityPolicy

Changing tags alone does not cause Nodes to be replaced. + +**Other platforms (Azure, KubeVirt, OpenStack, Agent, PowerVS):** + +Any change to the platform-specific machine template spec triggers a rollout. Refer to the API reference for the full list of fields per platform. + +## What Does Not Trigger a Rollout + +The following fields are propagated in-place to existing Nodes without triggering a rollout: + +| Field | Behavior | +|-------|----------| +| `spec.nodeLabels` | Propagated directly to existing Machine objects | +| `spec.taints` | Propagated directly to existing Machine objects | +| `spec.replicas` / `spec.autoScaling` | Only changes the number of Nodes, no replacement | +| `spec.nodeDrainTimeout` | Updated on existing Machines without replacement | +| `spec.nodeVolumeDetachTimeout` | Updated on existing Machines without replacement | +| `spec.management.replace.rollingUpdate` | Changes rollout parameters (maxSurge, maxUnavailable) but does not itself cause a rollout | +| `spec.management.autoRepair` | Toggles MachineHealthCheck without replacing Nodes | + +## Upgrade Types + +The upgrade type determines **how** Nodes are replaced or updated during a rollout. It is set once at NodePool creation and **cannot be changed** afterward. + +### Replace + +Replace upgrades create new Node instances with the updated configuration and remove old ones. This is the default and recommended approach for cloud environments where creating and destroying instances is cost-effective. + +The replacement process is governed by the `spec.management.replace` field: + +#### RollingUpdate Strategy (default) + +New Nodes are created before old Nodes are removed, ensuring workload availability during the rollout. + +| Parameter | Default | Description | +|-----------|---------|-------------| +| `maxSurge` | `1` | Maximum number of Nodes that can be provisioned above the desired count during the rollout. Can be an absolute number or a percentage. | +| `maxUnavailable` | `0` | Maximum number of Nodes that can be unavailable during the rollout. Can be an absolute number or a percentage. | + +With the defaults (`maxSurge=1`, `maxUnavailable=0`), one new Node is created at a time, and old Nodes are only removed after the new Node is ready. This is the safest configuration but also the slowest. + +To speed up the rollout, you can increase `maxSurge` (more Nodes created in parallel) or increase `maxUnavailable` (allow removing old Nodes before new ones are ready), at the cost of reduced capacity during the rollout. + +!!! important + + `maxSurge` and `maxUnavailable` cannot both be `0`. + +#### OnDelete Strategy + +Old Nodes are only replaced when they are manually deleted. This gives you full control over the rollout pace and order. Once an old Node is deleted, a new Node with the updated configuration is created to replace it. + +### InPlace + +InPlace upgrades update the operating system of existing Node instances without creating new ones. This is the recommended approach for environments with high infrastructure constraints, such as bare metal. + +| Parameter | Default | Description | +|-----------|---------|-------------| +| `maxUnavailable` | `1` | Maximum number of Nodes that can be unavailable during the in-place update. Can be an absolute number or a percentage. The minimum enforced value is `1`. | + +!!! important + + When using InPlace upgrades, platform-specific machine template changes (e.g. instance type, AMI) will **only apply to new Nodes** that are created after the change. Existing Nodes are not affected by platform changes. + +## Rollout Lifecycle + +When a rollout is triggered, the controller follows this sequence: + +1. **Change detection** — the controller compares the desired state (from the NodePool and HostedCluster specs) against the current state tracked in the NodePool status and annotations. + +2. **New configuration artifacts** — a new ignition token Secret and user-data Secret are generated with names derived from a hash of the new configuration. The previous token is marked as expired. + +3. **New machine template** (if platform fields changed) — a new platform-specific machine template is created. Its name includes a hash of the spec, so any change produces a distinct template. + +4. **Rollout execution**: + - **Replace:** the MachineDeployment is updated with the new user-data Secret, machine template, and version references. CAPI orchestrates Node creation and deletion according to the configured strategy (RollingUpdate or OnDelete). + - **InPlace:** the MachineSet is updated with the new target configuration. An in-place upgrader applies the changes to existing Nodes, respecting `maxUnavailable`. + +5. **Completion** — the rollout is considered complete when: + - **Replace:** all desired replicas are updated and available. + - **InPlace:** all Nodes report the target configuration version. + +6. **Status update** — `NodePool.status.version` is updated and the internal tracking annotations are set to the new values. + +### Monitoring Rollout Progress + +You can monitor rollout progress through the following NodePool conditions: + +| Condition | Meaning | +|-----------|---------| +| `UpdatingVersion` | A version rollout is in progress | +| `UpdatingConfig` | A configuration rollout is in progress | +| `UpdatingPlatformMachineTemplate` | A platform machine template rollout is in progress | + +These conditions are set to `True` while the corresponding rollout is in progress and are cleared when it completes. + +## Summary Table + +| Change | Triggers Rollout | Affects | +|--------|:---:|---------| +| `NodePool.spec.release.image` | Yes | The changed NodePool | +| `NodePool.spec.config` | Yes | The changed NodePool | +| `NodePool.spec.tuningConfig` | Yes | The changed NodePool | +| `HostedCluster.spec.pullSecret` (name change) | Yes | All NodePools | +| `HostedCluster.spec.additionalTrustBundle` (name change) | Yes | All NodePools | +| `HostedCluster.spec.imageContentSources` | Yes | All NodePools | +| `HostedCluster.spec.configuration.proxy` | Yes | All NodePools | +| `HostedCluster.spec.configuration.image` | Yes | All NodePools | +| Platform machine template fields | Yes | The changed NodePool | +| `NodePool.spec.nodeLabels` | No | Propagated in-place | +| `NodePool.spec.taints` | No | Propagated in-place | +| `NodePool.spec.replicas` / `autoScaling` | No | Scale only | +| `NodePool.spec.nodeDrainTimeout` | No | Propagated in-place | +| `NodePool.spec.management.autoRepair` | No | MachineHealthCheck toggle | +| AWS `spec.platform.aws.resourceTags` | No | Applied without rollout | + + --- ## Source: docs/content/reference/ocp-behaviour-deviations/index.md @@ -49340,6 +53061,1268 @@ HyperShift allows customers to just leave their NodePools on 4.17, while creatin - In the worst case, you can report the issue as a bug to the team for the further investigation. +--- + +## Source: docs/content/reference/service-publishing-strategies.md + +# Service Publishing Strategy Reference + +Service publishing strategies control how control plane services are exposed to external users and the data plane. + +## Overview + +### Services + +HostedClusters expose the following control plane services: + +- **APIServer**: The Kubernetes API server endpoint +- **OAuthServer**: The OAuth authentication service +- **Konnectivity**: The networking proxy service for control plane to data plane communication +- **Ignition**: The node ignition configuration service + +### Publishing Strategy Types + +Each service can be published using one of the following strategies: + +| Strategy Type | Description | Use Case | +|--------------|-------------|----------| +| **LoadBalancer** | Exposes the service through a dedicated cloud load balancer | Primary method for exposing KubeAPIServer in cloud environments without external DNS configured | +| **Route** | Exposes the service through OpenShift Routes and the management cluster's ingress controller | Default for most services; requires management cluster to have Route capability | +| **NodePort** | Exposes the service on a static port on each node | Used in on-premise and bare metal scenarios (Agent, None platforms) | + +### Terminology + +Understanding the following terms is essential for configuring service publishing strategies: + +| Term | Definition | +|------|------------| +| **Public** | Services accessible from the public internet.

Not accessible from the public internet. | +| **PublicAndPrivate** | Services accessible from both the public internet AND through private networking within the VPC. On AWS, this means endpoints are reachable externally and via PrivateLink. On GCP, this means endpoints are reachable externally and via Private Service Connect. | +| **External** | Refers to resources or endpoints accessible from outside the management cluster's VPC or network. Typically synonymous with "public" but may also include cross-VPC access. | +| **Internal** | Refers to resources or endpoints accessible only within the management cluster's VPC or network. Uses internal load balancers or private networking. | +| **External DNS** | A system that manages DNS records in a public or shared DNS zone. The `--external-dns-domain` flag enables this functionality, allowing custom hostnames for services. | +| **External Load Balancer** | A cloud load balancer with a public IP address, accessible from the internet. | +| **Internal Load Balancer** | A cloud load balancer with a private IP address, accessible only within the VPC or through private networking (e.g., PrivateLink). | +| **HCP Router** | A dedicated router (typically HAProxy or OpenShift Router) deployed within the Hosted Control Plane namespace, scoped to a specific hosted cluster. Used when Route publishing strategy is configured with external DNS. | +| **Management Cluster Ingress** | The shared ingress controller of the management cluster (e.g., OpenShift Router).
