Nginx Proxy for Docker API

Using Docker API being proxied by Nginx, to expose its information on some UI made with VueJS.

Based on Portainer: https://docs.portainer.io/v/ce-2.9/start/install/server/docker/linux

Running Portainer:

docker volume create portainer_data

docker container run -d \
  -p 8000:8000 \
  -p 9443:9443 \
  --name portainer \
  --restart=always \
  -v portainer_data:/data \
  -v /var/run/docker.sock:/var/run/docker.sock \
  portainer/portainer-ce:2.9.3
# access on https://localhost:9443

docker container logs -f --tail 50 portainer

# clean up
docker container rm -f portainer
docker volume rm portainer_data

Registries

Docker Hub

https://hub.docker.com/repository/docker/juliocesarmidia/micro-portainer

export DOCKERHUB_USERNAME='juliocesarmidia'
export DOCKERHUB_TOKEN=''
# login
echo "$DOCKERHUB_TOKEN" | docker login docker.io -u "$DOCKERHUB_USERNAME" --password-stdin
# push image
docker image push "docker.io/$DOCKERHUB_USERNAME/micro-portainer:latest"

Github

https://github.com/juliocesarscheidt/micro-portainer/pkgs/container/micro-portainer

In order to use the GITHUB_TOKEN in CI with Github Actions to push the image to ghcr.io registry, we need to enable the following config in the package configuration:

Also, we need to add the repository to manage Actions access, and set the permission to write:

export GITHUB_USERNAME='juliocesarscheidt'
export GITHUB_TOKEN=''
# login
echo "$GITHUB_TOKEN" | docker login ghcr.io -u "$GITHUB_USERNAME" --password-stdin
# tag and push image
docker image tag "docker.io/juliocesarmidia/micro-portainer:latest" "ghcr.io/$GITHUB_USERNAME/micro-portainer:latest"
docker image push "ghcr.io/$GITHUB_USERNAME/micro-portainer:latest"
