# Watchtower

>  A process for automating Docker container base image updates.

> Watchtower is an application that will monitor your running Docker containers and watch for changes to the images that those containers were originally started from. If watchtower detects that an image has changed, it will automatically restart the container using the new image.

Le but est de tenir les images à jour.

## Authentification

Pour utiliser le service avec un _registry_ privé il faut générer un fichier
