$ docker push ${DOCKER_USER}/nginx-hello-world
# download published image
$ docker pull ${DOCKER_USER}/nginx-hello-world
When no image tag version is specified, latest is used by default.
# tag latest image with a fixed version
$ docker tag ${DOCKER_USER}/nginx-hello-world:latest ${DOCKER_USER}/nginx-hello-world:1.0.0
# publish image
$ docker push ${DOCKER_USER}/nginx-hello-world:1.0.0
# download published image
$ docker pull ${DOCKER_USER}/nginx-hello-world:1.0.0

# force delete all containers
$ docker ps -q -a | xargs docker rm -f
# delete all unused images
$ docker images -f "dangling=true" -q | xargs docker rmi
Other, less destructive clean up options:
# delete all stopped containers
$ docker ps -a -q -f status=exited | xargs docker rm -v
