A process for watching your Docker containers and automatically restarting them whenever their base image is refreshed.

$ docker ps

Every few mintutes watchtower will pull the latest *centurylink/wetty-cli* image and compare it to the one that was used to run the "wetty" container. If it sees that the image has changed it will stop/remove the "wetty" container and then restart it using the new image and the same `docker run` options that were used to start the container initially (in this case, that would include the `-p 8080:3000` port mapping).

## Usage

Watchtower is itself packaged as a Docker container so installation is as simple as pulling the `centurylink/watchtower` image.
Watchtower is itself packaged as a Docker container so installation is as simple as pulling the `v2tec/watchtower` image.

Since the watchtower code needs to interact with the Docker API in order to monitor the running containers, you need to mount */var/run/docker.sock* into the container with the -v flag when you run it.

## Updating Watchtower

If watchtower is monitoring the same Docker daemon under which the watchtower container itself is running (i.e. if you volume-mounted */var/run/docker.sock* into the watchtower container) then it has the ability to update itself. If a new version of the *centurylink/watchtower* image is pushed to the Docker Hub, your watchtower will pull down the new image and restart itself automatically.
