Upgrade Operator 3.4.x to 4.0.1 using Helm

Caution

AKO version 4.0.1 has breaking changes from previous major versions. Review the Breaking Changes before upgrading.

Overview

This page describes how to upgrade the Aerospike Kubernetes Operator (AKO) to the latest version using Helm.

Prerequisites

• Helm 3.x

Note

Do not skip intermediate AKO versions if you are starting from version 3.0.0. Upgrade to version 3.4.x or later before upgrading to version 4.0.1.

• Upgrade to 3.4.1

Upgrade CRD

Helm 3.x does not support the upgrade of Custom Resource Definitions (CRDs). You need to manually upgrade the CRD.

1. Replace the old CRDs with the new CRD:

   Caution

   Do not remove the old CRDs. This deletes all the Aerospike related CRs like AerospikeClusters, AerospikeBackups. Do not use kubectl replace with the --force flag as this also deletes all the Aerospike related CRs.

   kubectl replace -f https://raw.githubusercontent.com/aerospike/aerospike-kubernetes-operator/4.0.1/config/crd/bases/asdb.aerospike.com_aerospikeclusters.yaml
   kubectl replace -f https://raw.githubusercontent.com/aerospike/aerospike-kubernetes-operator/4.0.1/config/crd/bases/asdb.aerospike.com_aerospikebackupservices.yaml
   kubectl replace -f https://raw.githubusercontent.com/aerospike/aerospike-kubernetes-operator/4.0.1/config/crd/bases/asdb.aerospike.com_aerospikebackups.yaml
   kubectl replace -f https://raw.githubusercontent.com/aerospike/aerospike-kubernetes-operator/4.0.1/config/crd/bases/asdb.aerospike.com_aerospikerestores.yaml

2. Run the following command to add the Helm repository.

   helm repo add aerospike https://aerospike.github.io/aerospike-kubernetes-enterprise

   If the Helm repository is already added, update the index:

   helm repo update

3. Run the following command to upgrade AKO:

   helm upgrade aerospike-kubernetes-operator aerospike/aerospike-kubernetes-operator --version=4.0.0

Check AKO Logs

AKO runs as two replicas by default for higher availability. Run the following command to follow the logs for the AKO pods.

kubectl -n <release-namespace> logs -f deploymentaerospike-kubernetes-operator manager
