using remote Docker repository

introduction

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.

getting ready

eventually rename/retag the image accordingly

docker tag custom-ubuntu:latest pbraun9/ubuntu:latest

pushing an image to Docker Cloud

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

#export DOCKER_ID_USER="pbraun9"
docker login -u pbraun9
docker push pbraun9/ubuntu
# pbraun9/ubuntu:latest
docker push pbraun9/centos
docker push pbraun9/devuan-svr4
docker push pbraun9/devuan
docker push pbraun9/meet
