Hello everyone,
I’m trying to install Icinga for Kubernetes (0.2.0) and have taken two different approaches.
The first approach follows the description in ‘Running out of Cluster’ , the second as described under ‘Using Helm’.
Unfortunately, both approaches result in the same error at an early stage.
Directly after systemctl enable --now icinga-kubernetes syslog shows:

Installing the Helm Charts works without any problems.
But after a few seconds the corresponding pod runs into an error and ends in CrashLoopBackOff.

Does anyone have any idea what is causing this problem?
Some information about the test environment…
It is distributed monitoring with two Master but with local databases.
Both Master running the same version.
