Drone healthcheck in docker

Drone Support
1

Hello,

As title says, i was wondering how to add docker-compose health check to the drone/drone image, it looks like that the base image is very small, i tried to mount my own path like /usr/local/bin with go app that can do health check but i am getting file not found.

"oci runtime error: exec failed: container_linux.go:265: starting container process caused “no such file or directory”

Any ideas?

version: "2.1"

services:
  server:
    image: drone/drone:0.8.2
    ports:
      - 8585:8000
      - 9000
    volumes:
      - ./data:/var/lib/drone/
      - /usr/local/bin:/usr/local/bin
    restart: unless-stopped
    environment:
      - DRONE_OPEN=false
      - DRONE_ADMIN=UnAfraid
      - DRONE_GITHUB=true
      - DRONE_GITHUB_CLIENT=<github client>
      - DRONE_GITHUB_SECRET=<github secret>
      - DRONE_GITHUB_MERGE_REF=false
      - DRONE_SECRET=<my secret>
      - DRONE_HOST=https://drone.mydomain.com
    healthcheck:
      test: ["CMD", "/usr/local/bin/go-health-check", "tcp", "server", "8000"]
      interval: 10s
      timeout: 30s
      retries: 5

  agent:
    image: drone/agent:0.8.2
    command: agent
    restart: always
    depends_on: [ server ]
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - DRONE_SERVER=server:9000
      - DRONE_SECRET=<my secret>

I’ve solved it, seems like the default go build doesn’t produces dynamic-free binary, it had some dynamic dependencies, i’ve builded it with go build -extldflags "-static" and now it works.
