In the terminal || To create an image WITH A TAG (best practice) || 'hello-docker' repository name and ID '1':

docker build -t hello-docker:1 .

To see the existing docker images:

docker images

To delete a docker image, you can type first 3 chars of the image id after 'rm'. Example for image '5d7':

docker image rm 5d7 or docker rmi -f '5d7' or docker rmi -f hello-docker:1

To delete all stopped containers:

docker containers prune

Run an image

docker run hello-docker:1

To see only running images:

docker ps

To see ALL running images:

docker ps -a

Interactive mode. It opens the terminal directly.

docker run -it hello-docker:1 sh

As you do on github, go to hub.docker.com and create a repo: ex: hello-docker. Now we will push the image to this repo:

docker push dockerUserName/repoName:version docker push korals/hello-docker:v1

Pull a repo

docker pull korals/hello-docker:v1
