MAAS 2.2 production ready?

[Blake Rouse]

Florian,

Many people run MAAS today in production including the 2.2.2 release of
MAAS. You are running into bug lp:1702703 [1] where the region controller
will not run correctly without the "/bin/maas-rack" present. This was
recently fixed in the MAAS 2.3 version of MAAS that we are currently
developing.

A quick fix for this bug is to install the rack controller on the region
controller as well. There is no issues with doing this even if you plan on
not using that rack controller.

sudo apt install maas-rack-controller

Installing that package will make the /bin/maas-rack present for the region
controller to do what it needs to do.

Hopefully this solves the issue for you. Let me know if you need anymore
help.

Thanks,
