Docker

Use a 'tag' command on docker.

docker tag <image_id> <repository_name>:<tag>

Note: You can omit the part '<tag>' and only write '<repository_name>'. The meaning of the <tag> string after colon (:) of the repository name is that you can put a different version image by changing the date or versions.

docker tag <image_id> <repository_name>

List volumes

sudo docker volume ls -qf dangling=true

Delete unnecessary volumes

sudo docker volume rm $(sudo docker volume ls -qf dangling=true)

Kill all Docker containers

sudo docker kill $(sudo docker ps -q)
