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: "v1.25.2", commit: "b63b921837de8dd6ce480033e427ecfc5e34abcc", kubernetes version: "v1.25.0", go version: "go1.19.3", GOOS: "darwin", GOARCH: "arm64"

4. Optionally authenticate as the serviceaccount.

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

5. Switch to project

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

6. Run the operator

$ operator-sdk run --local
INFO[0000] Running the operator locally in namespace openshift-osd-metrics.
