Upgrade operator 2.1.0 to 2.2.0 using Helm

Prerequisites

• Helm 3.x

Upgrade CRD

Helm 3.x does not support the upgrade of CRDs. Therefore, CRD has to be upgraded by user manually.

Replace the old crd with new crd

caution

Do not remove the old crd as it deletes all the clusters. Do not use kubectl replace with --force flag as that also deletes all the Aerospike clusters.

kubectl replace -f https://raw.githubusercontent.com/aerospike/aerospike-kubernetes-operator/2.2.0/config/crd/bases/asdb.aerospike.com_aerospikeclusters.yaml

Get the helm chart

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

git clone https://github.com/aerospike/aerospike-kubernetes-operator.git
git checkout 2.2.0

The charts are in the aerospike-kubernetes-operator/helm-charts folder.

cd aerospike-kubernetes-operator/helm-charts

Upgrade Operator

Run the following command

helm upgrade aerospike-kubernetes-operator ./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 openshift-operators logs -f deployment/aerospike-kubernetes-operator manager
