Docker containers widget [Go]

[DVDAndroid]

Hi all, I've created a custom widget that displays a list of running (or stopped) Docker containers in your machine.

Here's a preview:

Installation and configuration are very simple:
you need to start a new Docker container:

  glance-docker-container-ext:
    image: dvdandroid/glance-docker-container-ext:1
    container_name: glance-docker-container-ext
    restart: unless-stopped
    environment:
      - DOCKER_HOST=unix:///var/run/docker.sock
      - PORT=8081 # Optional, default is 8081
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

then add in your glance.yml configuration the widget:

  - type: extension
    allow-potentially-dangerous-html: true
    url: http://glance-docker-container-ext:8081
    cache: 5m
    parameters:
      title: Docker Containers
      all: true
      order: name,status

finally, for every Docker container you want to be visible in the dashboard, you need to add these labels (example):

    labels:
      glance.enable: true
      glance.name: Sonarr
      glance.description: TV show search
      glance.url: http://sonarr.lan
      glance.icon: ./assets/imgs/television-classic.svg

Repository is available here, more details in the README

_{^{it's one of my first Go programs, so contributions or tips are welcome}}

Very nicely done, thanks for sharing! I'll pin this to give it some well deserved exposure.

I got error when try pull the image in portainer, its says unauthorized.

failed to deploy a stack: glance-docker-container-ext Pulling glance-docker-container-ext Error Error response from daemon: Head "https://ghcr.io/v2/dvdandroid/glance-docker-container-ext/manifests/latest": unauthorized

Pulling from Github package registry requires authentication see here.

I don't quite know how to authenticate Github registry within portainer.
If really needed, I'll push the image to DockerHub

[dnlnm]

@DVDAndroid Login the registry with fresh token. Run docker pull, instead of unauthorized, now I got different error.

Error response from daemon: denied

It also shows 404 error when try to open the image link in browser.

Images pushed to Dockerhub, ghcr image should work now

This looks great, but I'm actually too stupid to get this running.

For me it just says: No containers found

Where do I have to put the labels? Can you show me a full example of a config?

More examples and documentation are available on repo README. This issue may be useful too

wow.. i was trying to add the labels in the glanc.yml instead of the docker containers themselves... thank you
