docker start bb6e63edc932
docker stop NAME of file (ubuntu)
docker rm NAME of file (ubuntu)

#Committing Changes in a Container to a Docker Image

docker images

#Pushing Docker Images to a Docker Repository
docker login -u docker-registry-username
docker login -u afahitech

  #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 ataur/ubuntu-nginx afahitech/ubuntu-nginx

#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 afahitech/ubuntu-nginx
