Kubeasy Registry

The registry is the source of truth for all Kubeasy challenges. It serves challenge metadata, objectives, and manifests to the CLI and the web app via a simple HTTP API.

What's in here

challenges/            # All challenge definitions (Git = source of truth)
  pod-evicted/
    challenge.yaml     # Metadata + objectives
    manifests/         # Kubernetes manifests (broken state)
    policies/          # Kyverno policies (bypass prevention)
  ...

pkg/challenges/        # Shared Go library — imported by the CLI
  types.go             # Challenge, Objective, all spec types
  parse.go             # YAML → typed structs
  validate.go          # Structural validation
  loader.go            # Scan a directory and load all challenges

internal/
  server/server.go     # HTTP handlers (chi router)
  store/store.go       # In-memory challenge store

cmd/
  root.go              # --challenges-dir flag
  serve.go             # registry serve
  validate.go          # registry validate [slug]

main.go                # Entrypoint

API

Endpoint	Description
GET /challenges	List all challenges
GET /challenges/{slug}	Full challenge JSON (metadata + objectives)
GET /challenges/{slug}/yaml	Raw challenge.yaml (used by CLI)
GET /challenges/{slug}/manifests	.tar.gz of manifests/ + policies/

Running locally

mise install
go run . serve
# CHALLENGES_DIR defaults to ./challenges

Override the challenges directory:

go run . serve --challenges-dir /path/to/challenges

Validate challenges

go run . validate           # all challenges
go run . validate pod-evicted  # single challenge

Adding a challenge

1. Create a folder under challenges/ (folder name = slug)
2. Add challenge.yaml, manifests/, and optionally policies/
3. Push — Railway redeploys automatically, CI validates on PR

See CHALLENGE_GUIDELINES.md for the full spec.

Architecture

The registry is consumed by:

• kubeasy-cli — imports pkg/challenges for types, calls /challenges/{slug}/yaml for runtime data
• monorepo API — calls the registry HTTP API and fan-outs challenge data alongside user progress

See the Kubeasy CLAUDE.md for the full system architecture.
