Upgrade Dapr on a Kubernetes cluster

Upgrade Dapr on a Kubernetes cluster

Follow these steps to upgrade Dapr on Kubernetes and ensure a smooth upgrade.

Prerequisites

Dapr CLI
Helm 3 (if using Helm)

Upgrade existing cluster to 1.0.1

There are two ways to upgrade the Dapr control plane on a Kubernetes cluster using either the Dapr CLI or Helm.

Dapr CLI

The example below shows how to upgrade to version 1.0.1:

dapr upgrade -k --runtime-version=1.0.1

You can provide all the available Helm chart configurations using the Dapr CLI. See here for more info.

Helm

From version 1.0.0 onwards, upgrading Dapr using Helm is no longer a disruptive action since existing certificate values will automatically be re-used.

Upgrade Dapr from 1.0.0 (or newer) to any [NEW VERSION] > v1.0.0:
```
helm repo update
```
```
helm upgrade dapr dapr/dapr --version [NEW VERSION] --namespace dapr-system --wait
```
If you’re using a values file, remember to add the --values option when running the upgrade command.

Ensure all pods are running:

kubectl get pods -n dapr-system -w
NAME                                     READY   STATUS    RESTARTS   AGE
dapr-dashboard-69f5c5c867-mqhg4          1/1     Running   0          42s
dapr-operator-5cdd6b7f9c-9sl7g           1/1     Running   0          41s
dapr-placement-server-0                  1/1     Running   0          41s
dapr-sentry-84565c747b-7bh8h             1/1     Running   0          35s
dapr-sidecar-injector-68f868668f-6xnbt   1/1     Running   0          41s

Restart your application deployments to update the Dapr runtime:
```
kubectl rollout restart deploy/<DEPLOYMENT-NAME>
```
All done!
