salt bundle for openSUSE MicroOS and openSUSE Tumbleweed

[juliogonzalez]

Short description

Having the salt bundle for such OS (basically the same code), should allow us to allow both OS and run then as a basic PoC at least.

Details

What I tried without the bundle and openSUSE MicroOS

1. I used this PR: openSUSE Leap Micro 5.3 and openSUSE MicroOS as clients #6550 (should get merged soon)
2. Edited /etc/rhn/rhn.con and added web.ssh_use_salt_thin=true at the end. Then restarted all the services (rebooting the Uyuni server is also valid)
3. Synced the openSUSE microOS channels with spacewalk-common-channels
4. This creates a bootstrap repository without the bundle, but with the salt-minion package and require dependencies.
5. Created an openSUSE MicroOS VM, and installed python3 (then rebooted)
6. Bootstrapping from WebUI fails with the message:

My guess is that we push our current salt 3004 for salt-ssh, and it doesn't work with the current python3.10 that Tumbleweed provides.
7. As an alternative, I installed salt-minion manually on the VM, then configured /etc/salt/minion/ to point to my Salt Master, and restarted salt-minion. With that, the master saw the minion key, and I could accept it from the Uyuni UI.
8. At that point the communication is broken:
At the master I saw:

 2023-02-02 14:59:46,781 [salt.master      :1644][ERROR   ][14929] Received minion error from [n241.mgr.suse.de]: The minion function caused an exception

At the minion I saw:

2023-02-02 13:59:40,493 [tornado.general  :568 ][WARNING ][1471] Got events for closed stream <zmq.eventloop.zmqstream.ZMQStream object at 0x7ff2600b81f0>
2023-02-02 13:59:46,715 [salt.minion      :2017][WARNING ][1560] The minion function caused an exception
2023-02-02 13:59:46,765 [tornado.general  :568 ][WARNING ][1471] Got events for closed stream <zmq.eventloop.zmqstream.ZMQStream object at 0x7ff2600b8040>

Here my guess is that Salt 3005 from Tumbleweed can't talk with our current Salt 3004 (I know, this is not supported, but in the past some basic functionality worked in such situations)

This list of workarounds could produce a valid minion as soon as we have Salt 3005 at the Uyuni server )when we switch it to openSUSE Leap 15.5 in Summer), but we should better produce a bundle ;-)

The bundle is available now, and I could do some progress during the hackweek, so closing.

Be aware it's still a PoC.
