Health Endpoints

The pre-built service exposes HTTP health endpoints for container orchestration.

Configuration

health {
http_port = 8080
readiness_path = "/health/ready"
liveness_path = "/health/live"
}

Endpoints

/health/live — Liveness

Returns 200 when the process is running and not deadlocked. Use as a Kubernetes liveness probe.

A pipeline in ERROR state does not affect liveness (the process is still healthy). If all pipelines on a source error out, liveness fails.

/health/ready — Readiness

Returns 200 when all pipelines have completed baseline and are streaming. Use as a Kubernetes readiness probe.

Returns a JSON body with per-pipeline status:

{
"ready": false,
"pipelines": {
"pg_main:public.config_document:indexed-memory": "STREAMING",
"pg_main:public.config_document:http-sync": "STREAMING",
"pg_main:public.audit_log:http-sync": "ERROR: HTTP 503 after 5 retries"
}
}

/health/startup — Startup

Returns 200 when the service has initialized and begun baseline (may not be complete). Use as a Kubernetes startup probe with a generous failureThreshold to allow time for large baselines.

periodSeconds: 5
failureThreshold: 60 # 5 minutes for initial baseline
