Upgrade Operator 3.1.0 to 3.2.2 using Helm

Prerequisites

• Helm 3.x

note

Do not skip intermediate Operator versions if you are starting from version 3.0.0. Upgrade to version 3.1.0 first before upgrading to version 3.2.2.

After the Helm upgrade, follow these steps to upgrade from a version before 3.0.0 directly to AKO 3.2.2:

1. Re-grant RBAC to all watched namespaces where Aerospike clusters are running by following these instructions
2. Remove deprecated v1beta1 version from AerospikeCluster CustomResourceDefinition by following these instructions

1. Upgrade CRD

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

Replace the old CRD with the new CRD:

caution

Do not remove the old CRD. This deletes all the Aerospike clusters. Do not use kubectl replace with the --force flag as this also deletes all the Aerospike clusters.

kubectl replace -f https://raw.githubusercontent.com/aerospike/aerospike-kubernetes-operator/3.2.2/config/crd/bases/asdb.aerospike.com_aerospikeclusters.yaml

2. Get the Helm chart

To get the Helm chart, clone the aerospike/aerospike-kubernetes-operator Git repository.

git clone https://github.com/aerospike/aerospike-kubernetes-operator.git
cd aerospike-kubernetes-operator
git checkout 3.2.2

3. Upgrade Operator with Helm

The charts are in the helm-charts folder in the Operator repository. While still in the aerospike-kubernetes-operator directory, run the following command:

helm upgrade aerospike-kubernetes-operator helm-charts/aerospike-kubernetes-operator

Check Operator Logs

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

kubectl -n <release-namespace> logs -f deployment/aerospike-kubernetes-operator manager
