Install RukPak

$ kubectl apply -f https://github.com/operator-framework/rukpak/releases/latest/download/rukpak.yaml

Demo:

1. Install the prometheus operator using a bundleDeployment

$ kubectl apply -f -<<EOF
apiVersion: core.rukpak.io/v1alpha1
kind: BundleDeployment
metadata:
  name: prometheus
spec:
  provisionerClassName: core-rukpak-io-plain
  template:
    metadata:
      labels:
        app: prometheus
    spec:
      provisionerClassName: core-rukpak-io-registry
      source:
        type: image
        image:
          ref: quay.io/agreene/prometheus:v1
EOF
bundledeployment.core.rukpak.io/prometheus created

2. Check that the prometheus bundleDeployment was installed successfully:

$ kubectl get bundledeployments
NAME         ACTIVE BUNDLE       INSTALL STATE           AGE
prometheus   prometheus-z55c54   InstallationSucceeded   6m21s

3. Check that the expected resources were created

$ kubectl get bundles
NAME                TYPE    PHASE      AGE
prometheus-z55c54   image   Unpacked   7m16s

$ kubectl get pods -n prometheus-system
NAME                                   READY   STATUS    RESTARTS   AGE
prometheus-operator-5bbbb6b6cf-tvpv4   1/1     Running   0          14s

$ kubectl get crds
NAME                                        CREATED AT

$ kubectl get deployments -n prometheus-system
NAME                  READY   UP-TO-DATE   AVAILABLE   AGE
prometheus-operator   1/1     1            1           56s

4. Update the bundle referenced by the bundleDeployment

$ kubectl patch bundledeployment prometheus --type=merge -p '{"spec": {"template": {"spec":{"source": {"image": {"ref": "quay.io/agreene/prometheus:v2"}}}}}}'
bundledeployment.core.rukpak.io/prometheus patched

5. Check that the bundle is being updated:

$ kubectl get bundles
NAME                TYPE    PHASE      AGE
prometheus-dcdxz5   image   Pending    1s
prometheus-z55c54   image   Unpacked   25s

6. Check that the deployment now points to the new bundle and confirm that the old bundle was deleted

$ kubectl get bundledeployment
NAME         ACTIVE BUNDLE       INSTALL STATE           AGE
prometheus   prometheus-dcdxz5   InstallationSucceeded   5m10s

$ kubectl get bundles
NAME                TYPE    PHASE      AGE
prometheus-dcdxz5   image   Unpacked    20s

7. Uninstall the prometheus operator

$ kubect delete bundledeployment prometheus
