Upgrade Dapr on a Kubernetes cluster

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

Prerequisites

Upgrade existing cluster to 1.0.0 / 1.0.0-rc.3

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

Dapr CLI

The example below shows how to upgrade to version 1.0.0-rc.3

dapr upgrade -k --runtime-version=1.0.0-rc.3  

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

Helm

From version 1.0.0-rc.3 onwards, upgrading Dapr using Helm is no longer a disruptive action since existing certificate values will automatically be re-used.

  1. Upgrade Dapr from 1.0.0-rc.1 (or newer) to 1.0.0-rc.3 (or newer):

    helm repo update
    
    helm upgrade dapr dapr/dapr --version 1.0.0-rc.3 --namespace dapr-system --wait
    

    If you’re using a values file, remember to add the --values option when running the upgrade command.

  2. 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
    
  3. Restart your application deployments to update the Dapr runtime:

    kubectl rollout restart deploy/<DEPLOYMENT-NAME>
    
  4. All done!
