Prometheus monitoring doc doesn't help to get monitoring working

[bjethwan]

Doc: https://camel.apache.org/camel-k/1.9.x/observability/monitoring.html

As per the doc, I installed prometheus-operator.
$ kubectl apply -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/main/bundle.yaml

Check the error below:

customresourcedefinition.apiextensions.k8s.io/alertmanagerconfigs.monitoring.coreos.com created

Next statement doesn't work

@bjethwan The below error suggests you should do kubectl create -f instead of kubectl apply -f.

The CustomResourceDefinition "prometheuses.monitoring.coreos.com" is invalid: metadata.annotations: Too long: must have at most 262144 bytes

Could you try the following and see if it works?

$ kubectl delete -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/main/bundle.yaml
$ kubectl create -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/main/bundle.yaml

If it works, we can just update our docs.

I've recently published a blog. Have a look here to see how to install the Prometheus stack on kubernetes.
