Alternative version for people who use `docker run` and no composes. Consider that this will restart updated containers without taking into account any other containers relying or depending on said container - might need to restart relating containers afterwards.

### Wont auto-update the containers, only their images. (compose is recommended)
|
||||
Alternative version for people who use `docker run` and no composes.
|
||||
`docker run` dont support using new images just by restarting a container.
|
||||
Containers need to be stopped, removed and created again to run on the new image.
