using remote Docker repository


sign up an account at Docker Cloud and create a repository named after the image you want to push e.g. ubuntu. The image will then be pullable from your docker host as LOGIN/REPOSITORY.

pushing an image to Docker Cloud

retag your image accordingly and push it to the public or private repo,

docker tag custom/ubuntu:latest pbraun9/ubuntu:latest
export DOCKER_ID_USER="pbraun9"
docker login
docker push pbraun9/ubuntu
#docker push pbraun9/ubuntu:latest
