# 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.
|
||
|
|
|
||
|
|
There is a nice docker image that solves this issue and can be very helpful. The image is: [v2tec/watchtower](https://hub.docker.com/r/v2tec/watchtower/).
|
||
|
|
|
||
|
|
A docker-compose example:
|
||
|
|
```yaml
|
||
|
|
services:
|
||
|
|
watchtower:
|
||
|
|
restart: always
|
||
|
|
image: v2tec/watchtower:latest
|
||
|
|
volumes:
|
||
|
|
- /var/run/docker.sock:/var/run/docker.sock
|
||
|
|
```
|
||
|
|
|
||
|
