Upgrading the VerticaDB operator

Vertica supports two separate options to upgrade the VerticaDB operator:.

Vertica supports two separate options to upgrade the VerticaDB operator:

OperatorHub.io
Helm Charts

Note

You must upgrade the operator with the same option that you selected for installation. For example, you cannot install the VerticaDB operator with Helm charts, and then upgrade the operator in the same environment using OperatorHub.io.

Prerequisites

Complete Installing the Vertica DB operator

OperatorHub.io

The Operator Lifecycle Manager (OLM) operator manages upgrades for OperatorHub.io installations. You can configure the OLM operator to upgrade the VerticaDB operator manually or automatically with the Subscription object's spec.installPlanApproval parameter.

Automatic upgrade

To configure automatic version upgrades, set spec.installPlanApproval to Automatic, or omit the setting entirely. When the OLM operator refreshes the catalog source, it installs the new VerticaDB operator automatically.

Manual upgrade

Upgrade the VerticaDB operator manually to approve version upgrades for specific install plans. To manually upgrade, set spec.installPlanApproval parameter to Manual and complete the following:

Verify if there is an install plan that requires approval to proceed with the upgrade:
```
$ kubectl get installplan
NAME CSV APPROVAL APPROVED
install-ftcj9 verticadb-operator.v1.7.0 Manual false
install-pw7ph verticadb-operator.v1.6.0 Manual true
```
The command output shows that the install plan install-ftcj9 for VerticaDB operator version 1.7.0 is not approved.

Approve the install plan with a patch command:

$ kubectl patch installplan install-ftcj9 --type=merge --patch='{"spec": {"approved": true}}'
installplan.operators.coreos.com/install-ftcj9 patched

After you set the approval, the OLM operator silently upgrades the VerticaDB operator. To monitor its progress, inspect the STATUS column of the Subscription object:


$ kubectl describe subscription subscription-object-name

Helm charts

The CRD is included when you install the Helm chart, but the helm install command does not overwrite an existing CRD. To upgrade the operator, you must update the CRD with the manifest from the GitHub repository. Upgrading the operator with the CRD requires the following prerequisites:

Cluster administrator privileges
Complete Installing the Vertica DB operator

Additionally, you must upgrade the VerticaAutoscaler CRD and the EventTrigger CRD, even if you do not use either in your environment. These CRDs are installed with the operator and maintained as separate YAML manifests. Upgrade the VerticaAutoscaler and EventTrigger to ensure that your operator is upgraded completely.

Use kubectl apply to upgrade the CRDs:

Upgrade the VerticaDB operator CRD:

$ kubectl apply -f https://github.com/vertica/vertica-kubernetes/releases/latest/download/verticadbs.vertica.com-crd.yaml

Upgrade the VerticaAutoscaler CRD:

$ kubectl apply -f https://github.com/vertica/vertica-kubernetes/releases/latest/download/verticaautoscalers.vertica.com-crd.yaml

Upgrade the EventTrigger CRD:

$ kubectl apply -f https://github.com/vertica/vertica-kubernetes/releases/latest/download/eventtriggers.vertica.com-crd.yaml

Upgrade the Helm chart:

$ helm upgrade operator-name --wait vertica-charts/verticadb-operator
