1. 2.1 Keeping Changes Made to a Container by Committing
   
2. to an Image
   
3. Problem
   
4. After making some changes inside a container, you decide that you would like to keep
   
5. those changes. You do not want to lose those changes after you exit or stop the container,
   
6. and you would like to reuse this type of container as a basis for others.
   
7. Solution
   
8. Commit the changes that you made by using the docker commit command and
   
9. define a new image.
   
10. Let’s start a container with an interactive bash shell and update the packages in it:
    
11. $ docker run -t -i ubuntu:14.04 /bin/bash
    
12. root@69079aaaaab1:/# apt-get update
    
13. When you exit the container, it stops running, but it is still available to you until you
    
14. remove it entirely with docker rm. So before you do this, you can commit the
    
15. changes made to the container and create a new image, ubuntu:update. The name of
    
16. the image is ubuntu, and you add the tag update (see Recipe 2.6) to mark the difference
    
17. from the ubuntu:latest image:
    
18. $ docker commit 69079aaaaab1 ubuntu:update
    
19. 13132d42da3cc40e8d8b4601a7e2f4dbf198e9d72e37e19ee1986c280ffcb97c
    
20. $ docker images
    
21. REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
    
22. ubuntu update 13132d42da3c 5 days ago 213 MB

1. 2.2 Saving Images and Containers as Tar Files for Sharing
   
2. Problem
   
3. You have created images or have containers that you would like to keep and share
   
4. with your collaborators.
   
5. Solution
   
6. Use the Docker CLI save and load commands to create a tarball from a previously
   
7. created image, or use the Docker CLI import and export commands for containers.
   
8. Let’s start with a stop container and export it to a new tarball:
   
9. $ docker ps -a
   
10. CONTAINER ID IMAGE COMMAND CREATED ... NAMES
    
11. 77d9619a7a71 ubuntu:14.04 "/bin/bash" 10 seconds ago ... high_shockley
    
12. $ docker export 77d9619a7a71 > update.tar
    
13. $ ls
    
14. update.tar
