healthcheck never goes to heathly state

[jeanmi151]

For docker compose health check it is required to install curl inside the container.

Here is an example of my docker-compose.yml

  mviewer:
    image: mviewer/mviewer:v4.1
    healthcheck:
      test: ["CMD-SHELL", "curl -s -f http://localhost:80/ >/dev/null || exit 1"]
      interval: 30s
      timeout: 10s
      retries: 10
    volumes:
      - ./volumes/mviewer-apps:/usr/share/nginx/html/apps
  mviewerstudio:
    image: mviewer/mviewerstudio:v4.3
    healthcheck:
      test: ["CMD-SHELL", "curl -s -f http://localhost:8000/mviewerstudio/index.html >/dev/null || exit 1"]
      interval: 30s
      timeout: 10s
      retries: 10
    environment:
      - CONF_PATH_FROM_MVIEWER=apps/store
      - CONF_PUBLISH_PATH_FROM_MVIEWER=apps/public
      - DEFAULT_ORG=my_org
      - EXPORT_CONF_FOLDER=/home/mvuser/apps/store
      - MVIEWERSTUDIO_PUBLISH_PATH=/home/mvuser/apps/public
      - MVIEWERSTUDIO_URL_PATH_PREFIX=mviewerstudio
    volumes:
      - ./volumes/mviewer-apps:/home/mvuser/apps
      - ./resources/mviewer-studio/config.json:/home/mvuser/src/static/config.json

With this sample mviewerstudio never goes to healthy state because the curl command is missing.

Notes it is installed in mviewer/mviewer:v4.1 image
