Icinga Kubernetes Role and Icinga Kubernetes Web install

[gianmarco-mameli]

Hello,
in the past month I tried the new Icinga Kubernetes daemon and module and, because my Icinga Infrastructure is outside of my K3S Cluster, I preferred to install the packages on the master nodes.
Using most of the excellent existent work, I copied the structures and implemented the installation of the daemon and db schema, in addition to the Icingaweb2 dedicated module.
The tasks are working and running correctly on my Icinga test installation (both existent and from scratch), so if you're interested I appreciate to check and merge my work.
I think I have covered most of the docs and files that needed update, but I certainly not a good expert to add the Molecule tests needed, so in that case maybe I need some help, but I'm already trying to fill the gaps

Thanks

PS. In my spare time I'm also implementing the same work for Dependencies and Fileshipper modules.

Hi, at the first glance this looks really good, thank you for the work. We'll review it as soon as possible and give you feedback.

Looks good to me so far.

The only thing is that I'm running into a bug where my apache web server fails completely for some reason a few minutes after having k3s, Icinga Web + Icinga-Kubernetes running (service okay, no errors in log, but 404 for every url).
This is likely unrelated though.

One more thing (could not add to my review somehow).

https://github.com/gianmarco-mameli/ansible-collection-icinga/blob/kubernetes_role_and_module/roles/icingaweb2/vars/main.yml#L1-L6

   director: icinga-director
   x509: icinga-x509
   businessprocess: icinga-businessprocess
+  kubernetes: icinga-kubernetes-web

This is needed so the mapping from icingaweb2_modules.kubernetes to the appropriate package can be made.

[gianmarco-mameli]

ok, I made the fix you suggested, thanks

We need a changelog fragment.

changelogs/fragments/feature_kubernetes.yml:

major_changes:
  - Add a role for the installation and configuration of `Icinga for Kubernetes <https://icinga.com/docs/icinga-for-kubernetes/latest/>`_.
  - Add tasks to role :code:`icingaweb2` to install and configure `Icinga for Kubernetes Web <https://icinga.com/docs/icinga-kubernetes-web/latest/doc/02-Installation/>`_.

@mkayontour, do you want to have another look at this as well?
