Howto: Container Health Monitoring

Autoheal is a Docker image that automatically restarts containers that are marked unhealthy. docker-mailserver tests itself regulary by using the healthcheck feature of Docker. When a test fails, the container state changes to unhealthy.

You can integrate autoheal into your setup by uncommenting the autoheal service definition in docker-compose.yml.

autoheal:
  image: willfarrell/autoheal:latest
  restart: always
  networks: []
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock:ro
  environment:
    - AUTOHEAL_CONTAINER_LABEL=de.ressourcenkonflikt.docker-mailserver.autoheal
