Tutorial on using portainer to connect to remote docker

Portainer is a lightweight docker environment management UI that can be used to manage docker hosts and docker swarm clusters. It is so lightweight that a Docker image container of less than 100M can provide complete services.

Portainer's Hub address is: https://hub.docker.com/r/portainer/portainer/

The command to run is:

docker run -it --restart=always -d --name portainer-docker -p 9000:9000 --privileged -v /var/run/docker.sock:/var/run/docker.sock portainer/portainer

Install portainer

> docker pull portainer/portainer

>docker run -d --name portainerUI -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock portainer/portainer
