If you're using Docker, you know you will need to update these containers from time to time by hand. Mostly with an docker pull repo/DockerContainerName and an docker-compose up -d. If you want to automate this, you can now use Watchtower: https://github.com/CenturyLinkLabs/watchtower
Using it, is very easy. Just run following command to let all your containers automatically update via watchtower:
docker run -d \
--name watchtower \
-v /var/run/docker.sock:/var/run/docker.sock \
centurylink/watchtower
If you want choosen containers to be updated, include the names of the running containers as arguments, i.e.:
docker run -d \
--name watchtower \
-v /var/run/docker.sock:/var/run/docker.sock \
centurylink/watchtower gogs_gogs_1 drone_drone_1
