Upgrade Dapr on a Kubernetes cluster

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

Prerequisites

Upgrade existing cluster to 1.1.2

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 1.1.2:

dapr upgrade -k --runtime-version=1.1.2

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

Troubleshooting upgrade using the CLI

There is a known issue running upgrades on clusters that may have previously had a version prior to 1.0.0-rc.2 installed on a cluster.

Most users should not encounter this issue, but there are a few upgrade path edge cases that may leave an incompatible CustomResourceDefinition installed on your cluster. The error message for this case looks like this:

❌  Failed to upgrade Dapr: Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply
The CustomResourceDefinition "configurations.dapr.io" is invalid: spec.preserveUnknownFields: Invalid value: true: must be false in order to use defaults in the schema

To resolve this issue please run the follow command to upgrade the CustomResourceDefinition to a compatible version:

kubectl replace -f https://raw.githubusercontent.com/dapr/dapr/5a15b3e0f093d2d0938b12f144c7047474a290fe/charts/dapr/crds/configuration.yaml

Then proceed with the dapr upgrade --runtime-version 1.1.2 -k command as above.

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.

  1. 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.

  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!
