Install Guide

The following instructions show you how to install Verrazzano in a single Kubernetes cluster.

Prerequisites

• Find the Verrazzano prerequisite requirements here.
• Review the list of the software versions supported and installed by Verrazzano.

Prepare for the install

Before installing Verrazzano, see instructions on preparing Kubernetes platforms.

NOTE: Verrazzano can create network policies that can be used to limit the ports and protocols that pods use for network communication. Network policies provide additional security but they are enforced only if you install a Kubernetes Container Network Interface (CNI) plug-in that enforces them, such as Calico. For instructions on how to install a CNI plug-in, see the documentation for your Kubernetes cluster.

Install the Verrazzano platform operator

Verrazzano provides a platform operator to manage the life cycle of Verrazzano installations. Using the Verrazzano custom resource, you can install, uninstall, and upgrade Verrazzano installations.

To install the Verrazzano platform operator:

1. Deploy the Verrazzano platform operator.

   $ kubectl apply -f https://github.com/verrazzano/verrazzano/releases/download/v1.2.2/operator.yaml
   

2. Wait for the deployment to complete.

   $ kubectl -n verrazzano-install rollout status deployment/verrazzano-platform-operator
   
   # Expected response
   deployment "verrazzano-platform-operator" successfully rolled out
   

3. Confirm that the operator pod is correctly defined and running.

   $ kubectl -n verrazzano-install get pods
   
   # Sample output
   NAME                                            READY   STATUS    RESTARTS   AGE
   verrazzano-platform-operator-59d5c585fd-lwhsx   1/1     Running   0          114s
   

Perform the install

Verrazzano supports the following installation profiles: development (dev), production (prod), and managed cluster (managed-cluster). For more information on profiles, see Installation Profiles.

This page shows how to create a basic Verrazzano installation using:

• The development (dev) installation profile
• Wildcard-DNS, where DNS is provided by nip.io (the default)

For a complete description of Verrazzano configuration options, see the Verrazzano Custom Resource Definition.

To use other DNS options, see the Customzing DNS page for more details.

Install Verrazzano

To create a Verrazzano installation as described in the previous section, run the following commands:

$ kubectl apply -f - <<EOF
apiVersion: install.verrazzano.io/v1alpha1
kind: Verrazzano
metadata:
  name: example-verrazzano
spec:
  profile: ${VZ_PROFILE:-dev}
EOF
$ kubectl wait \
    --timeout=20m \
    --for=condition=InstallComplete verrazzano/example-verrazzano

To use a different profile with the above example, set the VZ_PROFILE environment variable to the name of the profile you want to install.

If an error occurs, check the log output of the installation. You can view the logs with the following command:

$ kubectl logs -n verrazzano-install \
    -f $(kubectl get pod \
    -n verrazzano-install \
    -l app=verrazzano-platform-operator \
    -o jsonpath="{.items[0].metadata.name}") | grep '^{.*}$' \
    | jq -r '."@timestamp" as $timestamp | "\($timestamp) \(.level) \(.message)"'

For more help troubleshooting the installation, see Analysis Advice.

After the installation is complete, you can use the console URLs. For more information on how to access the Verrazzano consoles, see Access Verrazzano.

Verify the install

Verrazzano installs multiple objects in multiple namespaces. In the verrazzano-system namespaces, all the pods in the Running state, does not guarantee, but likely indicates that Verrazzano is up and running.

$ kubectl get pods -n verrazzano-system
