Delete an image

docker rmi IMAGE
docker image rm IMAGE

Delete a container

docker rm CONTAINER
docker container rm CONTAINER

Container run example

docker run --name=gogs -p 10022:22 -p 10080:3000 -v /var/gogs:/data gogs/gogs

This runs a container named gogs. You can connect to it on port 10022 and port 10080 of the host. It stores stuff in /var/gogs on the host, which translates to /data in the container

Automagically start

Make sure the container is set to restart. I probably use unless-stopped or always.

Update the settings of a running container

docker update can update settings.

docker update --restart unless-stopped prometheus
