[Feature Request] Docker Healthchecks

[alx-xlx]

Hey it would be an awesome feature to add the docker healthchecks.

I couldn't use curl , wget etc

Hi thanks for opening the request, could you share any wiki or documentation about "docker healthchecks"?

Docker Reference: https://docs.docker.com/reference/dockerfile/#healthcheck
Usually it's a HTTP Request to some health endpoint.

Yes that's correct, it is probably an easy fix. Just including either curl, wget, netstat commands etc in the docker image would do the trick.

and the following compose file with healthchecks will work fine.

services:
  beaverhabits:
    container_name: beaverhabits
    user: 1000:1000 # User permissions of your docker or default user.
    environment:
      # See the note below to find all the environment variables
      - HABITS_STORAGE=USER_DISK # DATABASE stores in a single SQLite database named habits.db. USER_DISK option saves in a local json file.
    volumes:
      - /home/pi/data/beaverhabits/habits:/app/.user/ # Change directory to match your docker file scheme.
    ports:
      - 8080:8080
    restart: unless-stopped
    image: daya0576/beaverhabits:latest
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:8080"]
      interval: 30s
      timeout: 5s
      retries: 3
      start_period: 10s
