--bootstrap-artifact-source Cache is required when updating ACR for AKS network isolated cluster #31209
Description
Describe the bug
When updating your ACR ID using "az aks update" for the feature network isolated cluster, both --bootstrap-artifact-source Cache and --bootstrap-container-registry-resource-id <New BYO ACR resource ID> need to be specified.
If --bootstrap-artifact-source Cache is not specified, the request will be ignored and the ACR ID won't be updated to the cluster.
