I'll publish a bugfix version as soon as i get back from FOSDEM so you might give it a try. I wrote few ansible playbooks for services I needed in jail like PostgreSQL, RabbitMQ, mail based on postfix+dovecot, etc. Reggae is inspired by docker compose and Vagrant, hence you can run multiple jails per project, like docker compose.

I always liked Bryan Cantrill’s dissection of Docker’s virtues here:

And I’ve seen a few people suggest the most crucial contribution of docker was the docker image format.
