If you plan on doing a test update with your own custom Docker image on Docker Hub, you will need a Docker Hub account.Docker installed on your server, following Steps 1 and 2 of how to install and use Docker on Ubuntu 22.04.An Ubuntu 22.04 server, set up according to our initial server setup guide for Ubuntu 22.04, with a non- root user with sudo privileges and a firewall enabled.To complete this tutorial, you will need: Additionally, a monitor-only solution coupled with email notifications is given for situations where automatic updates are not an option. Both methods are functionally the same in creating a container running Watchtower, then pointing it towards a container you wish to keep automatically updated. In this tutorial, you will use Watchtower with both Docker’s run command and Docker Compose to automatically update a Docker image. Your restarted container will be in the same state it initialized with, but with the new base Docker image applied. When Watchtower detects a new push, it will pull the new base image, gracefully shutdown your running container, and start it back up. This repository can be either public or private, and hosted on the Docker Hub registry or your own image registry.īy pushing a new Docker image to your repository, Watchtower will automatically trigger a chain of events to update your running container’s base Docker image. Specifically, it watches a specified Docker image repository for new Docker image pushes. Watchtower automates this process of detecting updates for your Docker container’s base image. Docker Hub is the most prominent registry, being the official registry hosted by the Docker team.īase Docker images are updated throughout the development process, but by default these updates must be manually pulled and applied to each running container. Docker repositories are subsequently stored in a Docker registry, which holds collections of repositories.

These repositories can store every iteration of a Docker image over time, as long as they share the same name and are differentiated by tags. Docker images may exist locally or be pulled remotely from Docker repositories. Every Docker container requires a Docker image as its base.
