Operator Lifecycle Manager

The Operator Lifecycle Manager (OLM) provides a declarative way to install and upgrade operators and their dependencies.

You can install the Starboard operator from OperatorHub.io or ArtifactHUB by creating the OperatorGroup, which defines the operator's multitenancy, and Subscription that links everything together to run the operator's pod.

As an example, let's install the operator from the OperatorHub catalog in the starboard-system namespace and configure it to watch the default namespaces:

  1. Install the Operator Lifecycle Manager:
    curl -L https://github.com/operator-framework/operator-lifecycle-manager/releases/download/v0.20.0/install.sh -o install.sh
    chmod +x install.sh
    ./install.sh v0.20.0
    
    or
    kubectl apply -f https://github.com/operator-framework/operator-lifecycle-manager/releases/download/v0.20.0/crds.yaml
    kubectl apply -f https://github.com/operator-framework/operator-lifecycle-manager/releases/download/v0.20.0/olm.yaml
    
  2. Create the namespace to install the operator in:
    kubectl create ns starboard-system
    
  3. Create the OperatorGroup to select all namespaces:
    cat << EOF | kubectl apply -f -
    apiVersion: operators.coreos.com/v1alpha2
    kind: OperatorGroup
    metadata:
      name: starboard-operator
      namespace: starboard-system
    spec:
      targetNamespaces: []
    EOF
    
  4. (Optional) Configure Starboard by creating the starboard ConfigMap and the starboard secret in the starboard-system namespace. For example, you can use Trivy in ClientServer mode or Aqua Enterprise as an active vulnerability scanner. If you skip this step, the operator will ensure default Settings on startup:
    kubectl apply -f https://raw.githubusercontent.com/aquasecurity/starboard/v0.15.8/deploy/static/03-starboard-operator.config.yaml
    
  5. Install default OPA Rego policies used by the built-in configuration checker:
    kubectl apply -f https://raw.githubusercontent.com/aquasecurity/starboard/v0.15.8/deploy/static/04-starboard-operator.policies.yaml
    
  6. Install the operator by creating the Subscription:
    cat << EOF | kubectl apply -f -
    apiVersion: operators.coreos.com/v1alpha1
    kind: Subscription
    metadata:
      name: starboard-operator
      namespace: starboard-system
    spec:
      channel: alpha
      name: starboard-operator
      source: operatorhubio-catalog
      sourceNamespace: olm
      installPlanApproval: Automatic
      config:
        env:
        - name: OPERATOR_EXCLUDE_NAMESPACES
          value: "kube-system,starboard-system"
    EOF
    
    The operator will be installed in the starboard-system namespace and will select all namespaces, except kube-system and starboard-system. Note that the spec.config property allows you to override the default Configuration of the operator's Deployment.
  7. After install, watch the operator come up using the following command:
    $ kubectl get clusterserviceversions -n starboard-system
    NAME                        DISPLAY              VERSION   REPLACES                     PHASE
    starboard-operator.v0.15.8  Starboard Operator   0.15.8    starboard-operator.v0.15.7   Succeeded
    
    If the above command succeeds and the ClusterServiceVersion has transitioned from Installing to Succeeded phase you will also find the operator's Deployment in the same namespace where the Subscription is:
    $ kubectl get deployments -n starboard-system
    NAME                 READY   UP-TO-DATE   AVAILABLE   AGE
    starboard-operator   1/1     1            1           11m
    
    If for some reason it's not ready yet, check the logs of the Deployment for errors:
    kubectl logs deployment/starboard-operator -n starboard-system
    

Uninstall

To uninstall the operator delete the Subscription, the ClusterServiceVersion, and the OperatorGroup:

kubectl delete subscription starboard-operator -n starboard-system
kubectl delete clusterserviceversion starboard-operator.v0.15.8 -n starboard-system
kubectl delete operatorgroup starboard-operator -n starboard-system
kubectl delete ns starboard-system

You have to manually delete custom resource definitions created by the OLM operator:

Danger

Deleting custom resource definitions will also delete all security reports generated by the operator.

kubectl delete crd vulnerabilityreports.aquasecurity.github.io
kubectl delete crd configauditreports.aquasecurity.github.io
kubectl delete crd clusterconfigauditreports.aquasecurity.github.io
kubectl delete crd ciskubebenchreports.aquasecurity.github.io
kubectl delete crd clustercompliancereports.aquasecurity.github.io
kubectl delete crd clustercompliancedetailreports.aquasecurity.github.io
