Docker Tools

Watchtower

  • allows us to update an already running docker container by simply pushing to Docker Hub. Watchtower sees that a new image has been pushed, automatically runs docker pull, then starts the container back up again.
  • note: a message from calibre:
    • We do not endorse the use of Watchtower as a solution to automated updates of existing Docker containers. In fact we generally discourage automated updates. However, this is a useful tool for one-time manual updates of containers where you have forgotten the original parameters. In the long term, we highly recommend using Docker Compose.

Portainer
