You can save it, and when you make changes to a container (by running a command in the container), you can save the changes to the container so that you can run the container from the latest state after saving next time.

The process of saving state in docker is called committing, which saves the difference between the old and new states, resulting in a new version. All changes made by docker in the container need commit to save to the elephant.

First use the docker ps-l command to get the id of the container after the ping command is installed. Then save the image as learn/ping.

1. Run docker commit to view a list of parameters for the command.

two。 You need to specify the ID of the container to be submitted for storage. (obtained through the docker ps-l command)

3. There is no need to copy the complete id, which can usually be distinguished by the first three or four letters. (very similar to the version number in git)

Command: $docker commit 698 learn/ping

After executing the docker commit command, the id number of the new version of the image is returned.
