pending

I have local docker volume enabled and I setup two docker container monitors. The state just remains at "pending".

Same here. Receiving the following error in the logs.

2025-01-18T21:02:34.769Z error: [NetworkService](requestDocker) connect EACCES /var/run/docker.sock (details: Error processing job 7: connect EACCES /var/run/docker.sock)

It appears the container may not have access to the Docker socket.

@ocean75 sounds like that's the case, you need to expose your docker daemon in order for Checkmate to use it to monitor containers

[ocean75]

Thank you, it worked perfectly using https://github.com/Tecnativa/docker-socket-proxy to expose the socket to Checkmate.

I'm using docker-socket-proxy but I also mounted the docker volume. But maybe that's why it's not working. Can you tell me how you configured it and the monitor to get it to monitor a docker container?

[ocean75]

Try removing the Docker volume and add an environmental DOCKER_HOST=tcp://docker-socket-proxy:2375 variable to the 'server' container.

server:
    container_name: CheckMate-Server
    image: bluewaveuptime/uptime_server:latest
    restart: unless-stopped
    ports:
      - "5000:5000"
    depends_on:
      - redis
      - mongodb
    environment:
      - DB_CONNECTION_STRING=mongodb://mongodb:27017/uptime_db
      - REDIS_HOST=redis
      - DOCKER_HOST=tcp://docker-socket-proxy:2375
    networks:
      - utility

For the monitor, use the container ID. You can find the ID by running docker ps.

[cirrusflyer]

Of course! Thanks. That works for me now too. How might one allow for multiple hosts? So the docker proxy on multiple servers and allowing Checkmate to check containers on them?

[ocean75]

I'm not sure; I haven't gotten that far yet in testing the application. I would assume the 'Capture' container may need to be rewritten to accept Docker containers.

By adding user: : to the server compose and read_only: true I was able to get container monitoring working without docker socket proxy.

  server:
   image: bluewaveuptime/uptime_server:latest
    restart: always
    user: nobody:281 # added
    read_only: true # added
