Or, you are able to use the option -d or --detach with that up.
docker compose up --detach && docker compose logs --follow
^cNow, in another terminal, you are able to access the provisioning container via docker compose exec command.
docker compose exec provisioning zsh -lNext, I recommend exporting several environment variables to access your new Mac from the provisioning service easily.
export TARGET_HOSTNAME=YOUR_VALUE
export TARGET_OS_USER=YOUR_VALUEYou are able to resolve the FQDN as has suffix .local via the dig @224.0.0.251 -p 5353 command if you are using an OS that is enabled mDNS services, such as Bonjour, or Avahi.
In this case, the DNS server 224.0.0.251 is a unique fixed IP address for mDNS and the correct IP address in all environments.
docker compose exec provisioning ansible -m raw -a hostname -i $(dig +short @224.0.0.251 -p 5353 ${TARGET_HOSTNAME}.local), -u ${TARGET_OS_USER} all
