Add functionality to automatically configure Icinga2 clients

[binarygraka]

Proposed Changes

I would like to add the following functionality:

• Install Icinga2 on a Debian/Ubuntu/RedHat/CentOS client.
• Configure the client as Icinga2 client by automatically running the node wizard and obtaining a ticket from the master.
• Add the client to an already existing Icinga2 master/satellite, using Top Down Command Endpoint configuration mode (https://www.icinga.com/docs/icinga2/latest/doc/06-distributed-monitoring/#top-down-command-endpoint).
• Make it possible to define the services that should be monitored on the Icinga2 client.

This would furthermore need the following changes regarding the directory structure of the formula:

• Move the current configuration for the icinga2 master in a state called icinga2.master.
• Add the aforementioned configuration for the icinga2 client to a state called icinga2.client.
• Check for files that can be used for both states and place them accordingly.

If this enhancement is favored, I can contribute via a pull request. Moreover it would be interesting to see who is currently active and responsible for this repository.

The other possibility would be to create a new repository in the group saltstack-formulas with only functionality for configuring and adding clients (e.g. icinga2-client-formula).

Thanks.

@binarygraka I suppose I'm currently the most active developer. :-)
My current strategy is to split the formula into building blocks. In my mind icinga2.master and icinga2.client would just re-use those building blocks and add needed functionality.

I don't see any problem with the proposed changes as long as they don't hinder or complicate "classic" master setups. icinga.client would be an opt-in then.

@aboe76 Would that be OK in your view?

@binarygraka Maybe #4 is of any help.

Has some progress been made on this feature ?

I might be willing to code this.

Thank you
