Hi folks,
I’m stuck in a rabbit hole since a few hours. I’m using a AKS Cubernetes Cluster and want to monitor it via the Module Icinga for Kubernetes. I installed the packages via apt-install as written in the documentation.
I made a empty database that is on my localhost and accessible.
I made a configuration file for my database (I checked that the database is accessible):
config.yml:
# This is the configuration file for Icinga for Kubernetes.
# Connection configuration for the database to which Icinga for Kubernetes synchronizes data.
# This is also the database used in Icinga for Kubernetes Web to view and work with the data.
database:
# Database type. Only 'mysql' is supported yet which is the default.
# type: mysql
# Database host or absolute Unix socket path.
host: localhost
# Database port. By default, the MySQL port.
# port:
# Database name.
database: kubernetes
# Database user.
user: kubernetes
# Database password.
password: test
Where I’m stuck since a few hours now is the start of the service.
If I run systemctl enable --now icinga-kubernetes I get the following error:

It dosen’t matter if I try it with or without password, with another or empty config file. I tried various versions. Only with a wron password it says me (what it shoud do, that the connection could not be made. I don’t get any error about an INVALIDARGUMENT then. Can anyone tell me what the problem is with the arguments (that I pasted from the example config file)?
