## Automatic Update
|
|
|
|
Docker images are handy but it can get a a hassle to keep them updated. Also when a repository is automated you want to get these images when they get out.
|
|
|
|
One could setup a complex action/hook-based workflow using probes, but there is a nice, easy to use docker image that solves this issue and could prove useful: [`watchtower`](https://hub.docker.com/r/containrrr/watchtower).
|
|
|
|
A docker-compose example:
|
|
|
|
```yaml
|
|
services:
|
|
watchtower:
|
|
restart: always
|
|
image: containrrr/watchtower:latest
|
|
volumes:
|
|
- /var/run/docker.sock:/var/run/docker.sock
|
|
```
|
|
|
|
For more details, see the [manual](https://containrrr.github.io/watchtower/)

## Automatic Cleanup
|
|
|
|
When you are pulling new images in automatically, it would be nice to have them cleaned up as well. There is also a docker image for this: [`spotify/docker-gc`](https://hub.docker.com/r/spotify/docker-gc/).
|
|
|
|
A docker-compose example:
|
|
|
|
```yaml
|
|
services:
|
|
docker-gc:
|
|
restart: always
|
|
image: spotify/docker-gc:latest
|
|
volumes:
|
|
- /var/run/docker.sock:/var/run/docker.sock
|
|
```
|
|
|
|
For more details, see the [manual](https://github.com/spotify/docker-gc/blob/master/README.md)
|
|
|
|
Or you can just use the [`--cleanup`](https://containrrr.github.io/watchtower/arguments/#cleanup) option provided by `containrrr/watchtower`.
