Bonjour,
A discourse was setup [as a multisite](https://meta.discourse.org/t/multisite-configuration-with-docker/14084) and runs six instances on six databases and six different domains. Every time a new instance is added, the container is rebuilt:
> ./launcher rebuild app
It takes a few minutes and while it is happening all forums are down. It has worked fine for the past few months and all is well. However, as the number of instances grow, the inconvenience of shutting down all of them every time a new one is added impacts an increasing number of users.
Is there a HOWTO to **add a new forum instance dynamically instead of rebuilding the app**?
Cheers

If the database is created and migrated and the multisite.yml is updated in the container, you can just do a `sv restart unicorn’, but I don’t think there’s a way to do that easily.
What I think you want is a two-container install so you can do the bootstrap while the old container containues to run.

Yes. That’s what I mean by a two container install.
