Let's say I have pulled the official mysql:5.6.21 image.
I have deployed this image by creating several docker containers.
These containers have been running for some time until MySQL 5.6.22 is released. The official image of mysql:5.6 gets updated with the new release, but my containers still run 5.6.21.
How do I propagate the changes in the image (i.e. upgrade MySQL distro) to all my existing containers? What is the proper Docker way of doing this?
If you do not want to use Docker Compose, I can recommend portainer. It has a recreate function that lets you recreate a container while pulling the latest image.
