Após um upgrade por:

```
git pull
./launcher rebuild app

```

O serviço não está iniciando nem mesmo com `./launcher start app`.

Estou recebendo um erro relacionado ao mac-address e não há um endereço MAC na linha de comando:

```plaintext
# ./launcher start app
x86_64 arch detected.

+ /data/docker-discourse/docker run --shm-size=512m -d --restart=always -h myhost-app -e DOCKER_HOST_IP=172.17.0.1 --name app -t --mac-address local_discourse/app /sbin/boot
docker: local_discourse/app is not a valid mac address.
See 'docker run --help'.

```

Como posso corrigir isso?
