Automate Container Updates with Ouroboros and Pushover Notifications


Keeping your Docker containers up-to-date with the latest versions is crucial for security and optimal performance. In this guide, we’ll introduce you to Ouroboros, a powerful Docker container that automates the update process. Additionally, we’ll show you how to receive Pushover notifications about container updates, so you can stay informed in real-time.

Step 1: Install Ouroboros with Docker

To install Ouroboros and run it in Docker, execute the following command:

docker run -d --name=ouroboros --hostname=ouroboros --network=host --restart=always -v /var/run/docker.sock:/var/run/docker.sock -e CLEANUP=true -e TZ='Europe/Copenhagen' -e INTERVAL=1440 pyouroboros/ouroboros:latest -N 'pover://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx?priority=0'

Explanation of options used:

  • -d: Run the container in the background (detached mode).
  • --name=ouroboros: Assign the name “ouroboros” to the container for easy management.
  • --hostname=ouroboros: Set the hostname for the container to “ouroboros.”
  • --network=host: Utilize the host’s network stack for efficient communication with other Docker containers.
  • --restart=always: Configure the container to automatically restart if it stops unexpectedly.
  • -v /var/run/docker.sock:/var/run/docker.sock: Mount the Docker daemon socket into the container to enable communication with the Docker daemon for updates.
  • -e CLEANUP=true: Enable automatic cleanup of unused images after updates to optimize disk space usage.
  • -e TZ='Europe/Copenhagen': Set the timezone for the container to “Europe/Copenhagen.” Adjust this according to your location.
  • -e INTERVAL=1440: Set the interval (in minutes) for checking updates. In this example, updates are checked every 1440 minutes (24 hours).
  • -N 'pover://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx?priority=0': Enable Pushover notifications for container updates. Replace the ‘xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx’ with your actual Pushover user key.

Step 2: Receive Pushover Notifications

With Ouroboros set up, you will now receive real-time Pushover notifications about container updates. Ensure you have the Pushover app installed on your device and configure it with the appropriate priority to suit your needs.


By deploying Ouroboros and integrating Pushover notifications, you’ve automated the process of updating Docker containers to their latest versions while staying informed about any changes. This proactive approach helps maintain a secure and high-performing containerized environment.

Enjoy hassle-free updates and timely notifications with Ouroboros and Pushover! Happy container management!
