docker-compose-updater

What is it good for?

This starts and docker-compose configuration and keeps the Containers updated with the referenced Image tag in your Docker Repository. It might be useful if you use an approach where where you push new versions of an image onto the same Docker tag like :latest or staging-latest.

The script pulls your new image before stopping the old one which helps to keep the downtime as low as possible.

How to use

docker run \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v $(pwd)/docker-compose.yml:/docker-compose-updater/docker-compose.yml \
  -e CHECK_INTERVAL_SEC=60 \
  stephanlindauer/docker-compose-updater

Note:

You need to map in the Docker socket

-v /var/run/docker.sock:/var/run/docker.sock

Map in the docker-compose.yml you want to run

-v $(pwd)/docker-compose.yml:/docker-compose-updater/docker-compose.yml

Set CHECK_INTERVAL_SEC or let it default to 60 seconds

-e CHECK_INTERVAL_SEC=1337
