You can use Helm to upgrade your YugabyteDB Anywhere (YBA) installed on Kubernetes to a newer version.

If you are upgrading a YugabyteDB Anywhere installation with high availability enabled, follow the instructions provided in Upgrade instances.

Before running an upgrade, execute the following command to obtain the latest versions of YugabyteDB Anywhere from Helm charts:

helm repo update

Upgrade using Helm

To upgrade to a specific version while preserving overrides you might have applied to your initial YugabyteDB Anywhere installation or previous upgrades, execute the following command:

helm upgrade yw-test yugabytedb/yugaware --version {{<yb-version version="v2.25" format="short">}} -n yb-platform --reset-then-reuse-values --set image.tag={{<yb-version version="v2.25" format="build">}} --wait

To obtain the value for --set image.tag, execute the following command:

helm list | awk '{if (NR!=1) print $NF}'

If you do not wish to port your overrides, do not include --reset-then-reuse-values. Instead, you may choose to pass your existing overrides file by adding --values custom-values.yaml to your command during the upgrade.

If you have upgraded YugabyteDB Anywhere to version 2.12 or later and xCluster replication for your universe was set up via yb-admin instead of the UI, follow the instructions provided in Synchronize replication after upgrade.

Install YugabyteDB Kubernetes Operator by upgrading an existing YBA

The YugabyteDB Kubernetes Operator {{<tags/feature/ea idea="831">}} automates the deployment, scaling, and management of YugabyteDB clusters in Kubernetes environments. You can install the operator by upgrading an existing YBA as follows:

Apply the following Custom Resource Definition:

kubectl apply -f https://raw.github.com/yugabyte/charts/{{< yb-version version="v2.25" format="short">}}/crds/concatenated_crd.yaml

Get a list of Helm chart releases in namespace using the following command:

helm ls

output

NAME    NAMESPACE       REVISION        UPDATED                                 STATUS          CHART           APP VERSION
yba         yb-platform-test      1               2024-05-08 16:42:47.480260572 +0000 UTC deployed        yugaware-2.19.3 2.19.3.0-b140

Run the following helm upgrade command to enable the YBA upgrade:

helm upgrade yba yugabytedb/yugaware --version 2.25.2 \
  --set yugaware.kubernetesOperatorEnabled=true,yugaware.kubernetesOperatorNamespace=yb-platform-test

Verify that YBA is up, and the Kubernetes Operator is installed successfully using the following commands:

kubectl get pods -n <yba_namespace>

kubectl get pods -n <operator_namespace>

output

NAME                                       READY   STATUS    RESTARTS   AGE
chart-1706728534-yugabyte-k8s-operator-0   3/3     Running   0          26h

Additionally, you should see no stack traces, but the following messages in the KubernetesOperatorReconciler log:

output

LOG.info("Finished running ybUniverseController");

Create the following custom resource, and save it as demo-universe.yaml.

yaml

# demo-universe.yaml
apiVersion: operator.yugabyte.io/v1alpha1
kind: YBUniverse
metadata:
  name: demo-test
spec:
  numNodes: 1
  replicationFactor: 1
  enableYSQL: true
  enableNodeToNodeEncrypt: true
  enableClientToNodeEncrypt: true
  enableLoadBalancer: true
  ybSoftwareVersion: "2024.1.0-b2" <- This will be the YBA  version
  enableYSQLAuth: false
  enableYCQL: true
  enableYCQLAuth: false
  gFlags:
    tserverGFlags: {}
    masterGFlags: {}
  deviceInfo:
    volumeSize: 100
    numVolumes: 1
    storageClass: "yb-standard"

Create a universe using the custom resource, demo-universe.yaml as follows:
sh
```
kubectl apply -f demo-universe.yaml -n yb-platform
```

Check the status of the universe as follows:

kubectl get ybuniverse  -n yb-operator

output

NAME                STATE   SOFTWARE VERSION
anab-test-2         Ready   2.23.0.0-b33
anab-test-backups   Ready   2.21.1.0-b269
anab-test-restore   Ready   2.21.1.0-b269
