Commit Changes

You have now made some improvements to your container environment. The next step is to commit them back to the image.

• Run exit in the interactive shell to leave the container.
• Run docker ps -a to list all containers. You should see your container named my_container.
• Copy the Container ID of my_container.
• Run

docker commit -m "Start off ros-melodic-base, add run_my_system simple script" -a "<FULL NAME>" <Container_ID> <USERNAME>/<IMAGE_REPOSITORY_NAME>:<TAG>

Notes:

• Your username must match the username of your Dockerhub account.
• The image repository name is the repository name that the image will be saved to on Dockerhub.
• The tag and colon are optional (but highly recommended) to help you version your images.

Example:

docker commit -m "Start off ros-melodic-base, add run_my_system simple script" -a "Tyler Lum" a0e1e92cb6a5 tylerlum/vorc-competitor-example:v2.2020

Test

The command above should have created a new image from your original. To make sure this worked, run

docker image ls

and verify that your new container is listed.
