# deis-cleanup
It's [Deis](https://github.com/deis/deis/) specific approach to `docker image`
cleanup. Currently available solutions are too io heavy or aren't configurable
enough.
## Usage
### Configuration
Use environment variables to pass the configuration. For example:
```
docker run --env "ENV_NAME=value" ...`
```
Possible options:
- `KEEP_LAST_VERSIONS` - the number of releases to keep for each repository (default: `2`).
- `DRY_RUN` - just print the commands (default: `false`).
- `EXCLUDE_REGEX` - regex filter for repository name (default: `alpine|deis|blackhole|none|datadog|cleanup|heroku|python`).
- `CLEANUP_CONTAINERS` - cleanup exited containers (default: `true`)
### deis-builder
1. Log onto the `deis-builder` container:
```
$ fleetctl ssh deis-builder
$ nse deis-builder
```
1. Pull `deis-cleanup` image:
```
$ docker pull twobox/deis-cleanup
```
1. Run `deis-cleanup`:
```
$ docker run -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/docker:/var/lib/docker --rm twobox/deis-cleanup
```
### Regular Deis node
#### Manual
Repeat for each Deis node:
1. Log onto a node:
```
$ fleetctl ssh
```
1. Follow steps 2. and 3. from usage on `deis-builder`.
#### Service
1. Load the service:
```
$ fleetctl load deis-cleanup.service
```
1. Start the service:

1. Wait until the process will finish and destroy it (optional):
```
$ fleetctl destroy deis-cleanup.service
```
