Actualización de un contenedor implementado basado en una imagen de Docker

A continuación, se explica cómo puede actualizar un contenedor implementado después de actualizar la imagen en Docker Hub.

Primero detienes el contenedor:

docker stop <ID or name>

Then you remove the container:

docker rm <ID or name>

Then you pull the image from Docker Hub:

docker pull <image name>

Then you start a new container from the image:

docker run <image name> ...options

Of course that’s not practical to do manually.

Applications like Watchtower, deployed as a Docker container, lets you setup an automated workflow for watching changes on Docker Hub (or any other image registry) and automatically gracefully shut down an existing container and restart it with the same options that were used to deploy it initially.
