The images pulled “hshar/mysql” and “hshar/webapp” remain to be up and cannot do anything to avoid that or delete them at all. If I delete the images (after stop and remove their container) after a few seconds they come mysteriously to live again. Even after stopping the containers and run in the terminal docker system prune --all they return to live once and again.
Why this behavior?
How can I remove permanently those images?
In this tutorial you don’t just start a container, but you create a swarm cluster. Take a look at the docs for docker service to learn more about it. Not sure if you really expect this when you want to learn about networking.
Yesterday after many attempts to avoid this behavior I’ve decided to remove the module docker.io and reinstall it again. After a first failed attempt (images and container continued to appear) I did a second try deleting the folder where docker saves the images. That last try was the good one.
It remains to the riddle of how a Image may be that persistent to die.
Thank you for you time and helping me about this issue.
