Some Docker notes of commands for reference

Images

Listing images

docker images

Running images

docker run <image name>

docker run <repo name>/<image name>

Building images

Create a Dockerfile file with the recipe therein.

docker build -t <image name> <parent subdir of Dockerfile>

 

Tagging images

Kinda like renaming; can be used to prepare for pushing

docker tag <image ID> <repo name>/<image name>:<version label or tag>

One version label is “latest.”

Pushing images

docker login --username=<user name> --email=<email>
docker push <image name>

Deleting images

docker rmi <repo name>

docker rmi <image ID>

The “-f” option is required if there are containers (even finished ones) referencing the image.

Containers

Kinda like processes.

Listing containers

docker ps -a

Deleting containers

docker rm <container ID>
