Build

show images docker images

List all images that are locally stored with the Docker Engine docker image ls

Delete an image from the local image store docker image rm alpine:3.4

Share

Pull an image from a registry docker pull myimage:1.0

Retag a local image with a new image name and tag docker tag myimage:1.0 myrepo/myimage:2.0

Push an image to a registry docker push myrepo/myimage:2.0

Containers

Run a container from the Alpine version 3.9 image, name the running container “web” and expose port 5000 externally, mapped to port 80 inside the container. docker container run --name web -p 5000:80 alpine:3.9

Stop a running container through SIGTERM docker container stop web

Stop a running container through SIGKILL docker container kill web

List the running containers (add --all to include stopped containers) docker container ls

docker container ps

Stop and remove all containers docker container stop $(docker container ls -aq)

Delete all running and stopped containers docker container rm -f $(docker ps -aq)

Allows you to remove containers based on a certain condition using the --filter option. docker container prune --filter "until=12h" -d -h -m

Print the last 100 lines of a container’s logs docker container logs --tail 100 web

Network

The default Docker network configuration allows for the isolation of containers on the Docker host. This feature enables you to build and configure apps that can communicate securely with each other. Docker provides three pre-configured network configurations:

• Bridge
• Host
• none

List the networks docker network ls

Volumes vs Bind Mounts

• With Bind Mount, a file or directory on the host machine is mounted into a container. The file or directory is referenced by its full or relative path on the host machine.
• With Volume, a new directory is created within Docker's storage directory on the host machine, and Docker manages that directory's content.
