Consider using docker-image-size-limit

I see that this project is focused on minimising docker image sizes. `docker-image-size-limit` might help in this case. It is a CLI tool to fail your build when image is too large.

Usage:

```
$ disl your-image-name:label 300MiB
your-image-name:label exceeds 300MiB limit by 114.4 MiB
```

Any feedback is welcome.
