I have an nginx-pod which redirects traffic into Kubernetes services and stores related certificates insides its volume. I want to monitor these certificates - mainly their expiration.
I found out that there is a TLS integration in Datadog (we use Datadog in our cluster): https://docs.datadoghq.com/integrations/tls/?tab=host.
They provide sample file, which can be found here: https://github.com/DataDog/integrations-core/blob/master/tls/datadog_checks/tls/data/conf.yaml.example
To be honest, I am completely lost and do not understand comments of the sample file - such as:
## @param server - string - required
## The hostname or IP address with which to connect.
- I want to monitor certificates that are stored in the pod, does it mean this value should be
localhostor do I need to somehow iterate over all the certificates that are stored using this value (such asserver_namesin nginx.conf)?
If anyone could help me with setting sample configuration, I would be really grateful - if there are any more details I should provide, that is not a problem at all.
