# Committing Changes in a Container to a Docker Image
docker commit -m "What you did to the image" -a "Author Name" container_id repository/new_image_name
docker commit -m "added Node.js" -a "linuxbiekaisar" d9b100f2f636 kaisar/ubuntu-nodejs
docker images

# Push Docker Images to a Docker Repository
docker login -u docker-registry-username
docker login -u linuxbiekaisar

  #Note: If your Docker registry username is different from the local username you used to create the image, you will have  to tag your image with your registry username. For the example given in the last step, you would type:
    sudo docker tag linuxbiekaisar/ubuntu-nodejs docker-registry-username/ubuntu-nodejs

#Then you may push your own image using:
docker push docker-registry-username/docker-image-name

#To push the ubuntu-nodejs image to the sammy repository, the command would be:
docker push kaisar/ubuntu-nodejs
