Yes, doing it the official way would almost certainly have given me fewer headaches (most likely none). The problem is that I’m not allowed to use docker images that are not pre-approved by our IT security department - and yours is not.
So this is indeed a custom, native install on RHEL8 machines, which also needed some SELinux trickery to work.
Maybe there are others out there with the same problem - perhaps it would be useful to them if I post a topic with my installation procedure? Feel free to protest - I can see that this could be taken as an “encouragement” to install it this way even if not strictly necessary, which could lead to more questions for you.
As an aside, when googling for solutions to any SELinux problem, the most frequent advice you will find is “this is how you disable it”
. But this is not an option here.
Thanks for your help!
