Support Docker health checks

[jmorino]

Hi, is there a way to integrate with Docker health checks ?

At the moment no, but contributions are welcome 👍

Here is my implementation of healtcheck for nginx-proxy and acme-companion.

I'm not sure it's very robust 🤔.

Still, it has the advantage of allowing me to use the --wait option in docker-compose up -d --remove-orphans --wait.

# docker-compose.yml
services:
  nginx-proxy:
    image: nginxproxy/nginx-proxy:1.6.4
    container_name: nginx-proxy
    restart: unless-stopped
    network_mode: "host"
    volumes:
      - ./vhost.d/:/etc/nginx/vhost.d:rw
      - ./htpasswd:/etc/nginx/htpasswd:ro
      - html:/usr/share/nginx/html
      - certs:/etc/nginx/certs:ro
      - /var/run/docker.sock:/tmp/docker.sock:ro
    healthcheck:
      test: ["CMD-SHELL", "nginx -t && kill -0 $$(cat /var/run/nginx.pid)"]
      interval: 10s
      timeout: 2s
      retries: 3

  acme-companion:
    image: nginxproxy/acme-companion:2.5.1
    restart: unless-stopped
    volumes_from:
      - nginx-proxy
    depends_on:
      - "nginx-proxy"
    environment:
      DEFAULT_EMAIL: [email protected]
    volumes:
      - certs:/etc/nginx/certs:rw
      - acme:/etc/acme.sh
      - /var/run/docker.sock:/var/run/docker.sock:ro
    healthcheck:
      test: ["CMD-SHELL", "ps aux | grep -v grep | grep -q '/bin/bash /app/start.sh'"]
      interval: 30s
      timeout: 3s
      retries: 3
      start_period: 10s
