Openshift Dedicated Metrics Exporter

A prometheus exporter to expose metrics about various features used in Openshift Dedicated Clusters.

Current Metrics

1. Identity Provider
2. Cluster Admin

Local development without OLM

1. Create Namespace, Role and RoleBinding. Requires yq.

$ for k in "Namespace" "Role" "RoleBinding"; do; k=$k yq '.objects[].spec.resources[] | select(.kind==strenv(k))' < hack/olm-registry/olm-artifacts-template.yaml|  oc create -f -; done

2. Create ClusterRole, ClusterRoleBinding and ServiceAccount.

$ oc -n openshift-osd-metrics create -f deploy/cluster_role_binding.yaml
clusterrolebinding.rbac.authorization.k8s.io/osd-metrics-exporter created
$ oc -n openshift-osd-metrics create -f deploy/cluster_role.yaml
clusterrole.rbac.authorization.k8s.io/osd-metrics-exporter created
$ oc -n openshift-osd-metrics create -f deploy/service_account.yaml
serviceaccount/osd-metrics-exporter created

3. Requires operator-sdk < 1.X

$ operator-sdk version
operator-sdk version: "v0.17.2", commit: "0258db0119e8e18e15d035532427c329fce1e871", kubernetes version: "v1.17.2", go version: "go1.18.2 linux/amd64"

4. Optionally authenticate as the serviceaccount.

$ oc login $(oc get infrastructures cluster -o json | jq -r '.status.apiServerURL') --token $(oc -n openshift-osd-metrics serviceaccounts get-token osd-metrics-exporter)

5. Switch to project

$ oc project openshift-osd-metrics
Now using project "openshift-osd-metrics" on server "https://api.sno.dofinn.xyz:6443".
