Config modification at Prometheus in Openshift cluster

[Andy Andy]

Hi everyone. Well, i deploy Prometheus on my Openshift cluster, but now I don't know how can i modify config file. Prometheus.yaml and prometheus.env.yaml is read-only and mounted as volume. And i try to look events at config reloaded and i got this: 

     command:
- /bin/prometheus-config-reloader
args:
- '--listen-address=localhost:8080'
- '--reload-url=http://localhost:9090/-/reload'
- '--config-file=/etc/prometheus/config/prometheus.yaml.gz'
- >-
--config-envsubst-file=/etc/prometheus/config_out/prometheus.env.yaml
- '--watched-dir=/etc/prometheus/rules/prometheus-k8s-rulefiles-0'

And i dont know what i should do. Can someone help? Thank a lot.

Hey Andy,

I'm going to assume that you are deploying Prometheus via the prometheus-operator? If so, you shouldn't need to modify the configuration file directly, as this will be managed via the Prometheus operator CRDs themselves (i.e. Prometheus, ServiceMonitor etc.)

For Prometheus-operator questions, please reach out to that community directly.

Best,

Ian

Thanks a lot for answer. Yes, prometheus operator. But how i can modify that and add targets? I mean i try to edit oc edit servicemonitor prometheus -n openshift-monitoring, but i cant see targets section. Documentation describe many different ways like edit secret, edit basic config file, edit servicemonitor and etc. and i just try to find my initial config.
