Edit the Verrazzano resource
The following sections show you how to modify the Verrazzano resource.
Before you install Verrazzano, you can define a Verrazzano resource manifest file that can be supplied at installation time.
The following is an example of a Verrazzano manifest file that enables two Verrazzano components,
velero, that are disabled by default.
apiVersion: install.verrazzano.io/v1beta1 kind: Verrazzano metadata: name: example-verrazzano spec: profile: dev components: argoCD: enabled: true velero: enabled: true
You can save this manifest file and supply it to the Verrazzano CLI at installation time.
$ vz install -f verrazzano.yaml
For detailed installation instructions, see the Install Guide.
Also, you can modify the Verrazzano resource after it has been installed. Updates to the Verrazzano resource will be reflected in the cluster. You must get the name of the Verrazzano resource to be able to edit it in the cluster. Verrazzano allows only one custom resource to exist per cluster.
$ kubectl get vz -A
# Sample output NAMESPACE NAME AVAILABLE STATUS VERSION default example-verrazzano 24/24 InstallComplete 1.5.0
After you have the name of the Verrazzano resource, you can edit its manifest file.
kubectl edit command lets you directly edit any API resource on the cluster.
For more information on
kubectl edit, see the kubectl edit documentation.
The following example edits the Verrazzano resource found in the previous sample output.
$ kubectl edit vz example-verrazzano
