Deployment

Now we have all our code changes and manifests in place, so let’s deploy it tothe cluster and test it out.

Ensure that you have installed cert-manager 0.9.0+ version in your cluster. We havetested the instructions in this tutorial with 0.9.0-alpha.0 release.

Running make deploy will deploy the controller-manager in the cluster.

Testing

Now that we have deployed the controller-manager with conversion webhook enabled, let’s test out the version conversion feature.We will do the following to perform a simple version conversion test:

• Create disk object named disk-sample using v1 specification
• Get disk object disk-sample using v2 version
• Get disk object disk-sample using v3 version

1. Create v1 disk object

apiVersion: infra.kubebuilder.io/v1
kind: Disk
metadata:
  name: disk-sample
spec:
  price: 10 USD

kubectl apply -f config/samples/infra_v1_disk.yaml

2. Get disk object using v2 version

kubectl get disks.v2.infra.kubebuilder.io/disk-sample -o yaml

apiVersion: infra.kubebuilder.io/v2 <-- note the v2 version
kind: Disk
metadata:
  name: disk-sample
  selfLink: /apis/infra.kubebuilder.io/v2/namespaces/default/disks/disk-sample
  uid: 0e9be0fd-a284-11e9-bbbe-42010a8001af
spec:
  price: <-- note the structured price object
    amount: 10
    currency: USD
status: {}

3. Get disk object using v3 version

kubectl get disks.v3.infra.kubebuilder.io/disk-sample -o yaml

apiVersion: infra.kubebuilder.io/v3 <-- note the v3 version
kind: Disk
metadata:
  name: disk-sample
  selfLink: /apis/infra.kubebuilder.io/v3/namespaces/default/disks/disk-sample
  uid: 0e9be0fd-a284-11e9-bbbe-42010a8001af <-- note the same uid as v2
  ....
spec:
  pricePerGB: <-- note the pricePerGB name of the field
    amount: 10
    currency: USD
status: {}
