Health Check

Astral

Utility to check health status of an internal service and expose it as a REST API endpoint. Currently supports following services:

  • Postgres
  • Services using Prometheus metrics:
    • ingest (Archive)
    • processor (Squid)

Available scripts

  • prometheus - start health check server for a service using Prometheus metrics
  • pg - start health check server for pg service
  • build - transpile TypeScript to ES6
  • lint - check codebase using ESLint

Running as Docker container

Example docker-compose.yml including health-check services for Postgres and service with Prometheus:

version: "3.7"

services:
  pg-health-check:
    image: ghcr.io/autonomys/health-check:latest
    environment:
      POSTGRES_HOST: db
      POSTGRES_PORT: 5432
      PORT: 8080
      # provide secret, which is going to be used in 'Authorization' header
      SECRET: MY_SECRET
    command: "postgres"
    ports:
      - 8080:8080

  prom-health-check:
    image: ghcr.io/autonomys/health-check:latest
    environment:
      # assuming we're running `ingest` service within same docker-compose.yml
      PROMETHEUS_HOST: http://ingest:9090
      PORT: 7070
      # provide secret, which is going to be used in 'Authorization' header
      SECRET: MY_SECRET
    command: "prometheus"
    ports:
      - 7070:7070
