Full example of ha cluster deployment

[fl0wx]

Hey ho, is there any example of a full ha cluster deployment with 2 master instances (including icinga2, icingaweb2, icingadb)? Or can you provide one? :)

thanks and regards

There's no official documentation (yet), but you could have a look at my homelab setup which provisions exactly this, using the collection.

One thing that isn't HA even after using the linked playbook is syncing file-based configuration of Icinga Web from one master instance to another. For this, you'd need to jump through quite some more hoops, unfortunately, which is why it's out of the scope of this collection.

Thanks a lot, I'm also looking for the same example for HA cluster with 2 masters .
My issue that I don't get the icinga2 service started and I have the following error when I run : icinga2 daemon -C

[2023-12-21 04:42:18 -0500] critical/config: Error: Endpoint object for 'icinga-primary-1' is missing.
Location: in /etc/icinga2/features-enabled/api.conf: 1:0-1:23

[2023-12-21 04:42:18 -0500] critical/config: 1 error

My config is like the following

icinga2_features:
  - name: api
    ca_host: none  
    endpoints:
      - name: icinga-primary-1.{{ env }}.local
        host: icinga-primary-1.{{ env }}.local
      - name: icinga-primary-2.{{ env }}.local
        host: icinga-primary-2.{{ env }}.local
    zones:
      - name: "master"
        endpoints:
          - icinga-primary-1.{{ env }}.local
          - icinga-primary-2.{{ env }}.local
          
icinga2_objects:
  icinga-primary-1.{{ env }}.local:
    - name: icingaweb
      type: ApiUser
      file: local.d/apiusers.conf
      password: "***********"
      permissions: ['*']
  
  icinga-primary-2.{{ env }}.local:
    - name: icingaweb
      type: ApiUser
      file: local.d/apiusers.conf
      password: "***********"
      permissions: ['*']

Not sure but did we need to create also Objects type Zone and Endpoints also or they are not needed. I tried them but also nothing was changed
Any idea ?

Thanks

Can you put the following in quotes:

icinga2_features:
  - name: api
    ca_host: none  
    endpoints:
      - name: "icinga-primary-1.{{ env }}.local"
        host: "icinga-primary-1.{{ env }}.local"
      - name: "icinga-primary-2.{{ env }}.local"
        host: "icinga-primary-2.{{ env }}.local"
    zones:
      - name: "master"
        endpoints:
          - "icinga-primary-1.{{ env }}.local"
          - "icinga-primary-2.{{ env }}.local"

I followed the same config example provided mocdaniel and also I tried with quotes but I'm still getting the same issue.

Ok, can you post the zones.conf, what is the result. Please post the following files zones.conf and constants.conf. If available redact secrets before posting.
