docker-compose.yml: - Builds the Dockerfile, exposes :8000 - Mounts ./data (persistent) and ./hadoop-conf (ro) for cluster configs - Forwards YARN_RESOURCE_MANAGER_URL via env var (fallback for REST client) - Healthcheck via /openapi.json (cheap liveness probe; MCP initialize handshake would be more accurate but requires session-id plumbing) - restart: unless-stopped for production - Resource limit section commented out (server itself is lightweight) .env.example: - Documents the env vars compose expects - .env is gitignored

# YARN ResourceManager URL the REST client falls back to when a Connection
|
|
# was saved without yarn_rm_url, or a Job lacks a snapshot (e.g. if the
|
|
# pending record was created before yarn_rm_url was a field).

# Examples:
|
|
# YARN_RESOURCE_MANAGER_URL=http://yarn-rm.prod.internal:8088

# YARN_RESOURCE_MANAGER_URL=https://yarn-rm.staging.example.com:8088
