Testing

Validation

# Validate OLM bundle
operator-sdk bundle validate olm/bundle --select-optional suite=operatorframework

# Run scorecard
operator-sdk scorecard olm/bundle

# Lint Helm chart
helm lint helm/hyper2kvm-operator

# Template Helm chart
helm template hyper2kvm-operator helm/hyper2kvm-operator \
  --set openshift.enabled=true \
  --debug

E2E Testing on OpenShift

# Deploy to test cluster
oc new-project hyper2kvm-test
helm install test hyper2kvm-operator \
  --namespace hyper2kvm-test \
  --set openshift.enabled=true

# Create test job
oc apply -f k8s/operator/examples/convert-job.yaml

# Verify
oc get migrationjobs -n hyper2kvm-test
oc logs -n hyper2kvm-test -l app.kubernetes.io/name=hyper2kvm-operator

Metrics

OpenShift-Specific Metrics

All standard operator metrics are exposed, with OpenShift integration:

Access via OpenShift Console:

  1. Observe → Metrics
  2. Query: hyper2kvm_*

Security

RBAC

Operator requires:

Pod Security

Operator pods: Restricted (non-root, read-only FS, no capabilities) Worker pods: Privileged (via SCC, for NBD/LVM operations)

Network

Next Steps

  1. Build bundle image: 
    docker build -f olm/bundle.Dockerfile -t ghcr.io/ssahani/hyper2kvm-operator-bundle:v2.1.0 olm/
docker push ghcr.io/ssahani/hyper2kvm-operator-bundle:v2.1.0
  2. Create catalog: 
    opm index add \
  --bundles ghcr.io/ssahani/hyper2kvm-operator-bundle:v2.1.0 \
  --tag ghcr.io/ssahani/hyper2kvm-operator-catalog:latest
  3. Test on OpenShift cluster: 
    operator-sdk run bundle ghcr.io/ssahani/hyper2kvm-operator-bundle:v2.1.0
  4. Submit to OperatorHub:
    • Fork https://github.com/k8s-operatorhub/community-operators
    • Add bundle to operators/hyper2kvm-operator/
    • Create PR
