watchtower - automatic image update

  • https://containrrr.dev/watchtower/
  • Use cases: https://www.howtogeek.com/devops/how-to-automate-docker-container-updates-with-watchtower/

Running On-Demand

Watchtower is designed to run as a long-lived daemon that continually monitors containers for updates. Sometimes you might want to manually check for new images on-demand. You can do this with the --run-once command flag:

docker run --rm \
    -v /var/run/docker.sock:/var/run/docker.sock \
    containrrr/watchtower --run-once

This will perform a single update attempt for all your running containers. The Watchtower container will then stop and be removed.

restirct to containers

you can restrict watchtower to monitoring a subset of the running containers by specifying the container names as arguments when launching watchtower.

docker run --rm \
    --name watchtower \
    -v /var/run/docker.sock:/var/run/docker.sock \
    containrrr/watchtower --run-once \
