Steps to upgrade Dapr on a Kubernetes cluster

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

Prerequisites

• Latest Dapr CLI
• Helm 3

Upgrade existing cluster running 0.11.x

1. Run these two commands to prevent helm upgrade from uninstalling 0.11.x placement service:

   kubectl annotate deployment dapr-placement helm.sh/resource-policy=keep -n dapr-system

   kubectl annotate svc dapr-placement helm.sh/resource-policy=keep -n dapr-system

2. Export certificates:

   dapr mtls export -o ./certs

3. Upgrade Dapr to 1.0.0-rc.2:

   helm repo update

   helm upgrade dapr dapr/dapr --version 1.0.0-rc.2 --namespace dapr-system --reset-values --set-file dapr_sentry.tls.root.certPEM=./certs/ca.crt --set-file    dapr_sentry.tls.issuer.certPEM=./certs/issuer.crt --set-file dapr_sentry.tls.issuer.keyPEM=./certs/issuer.key --set global.ha.enabled=true --wait

4. Upgrade CRDs:

   kubectl replace -f https://raw.githubusercontent.com/dapr/dapr/21636a9237f2dcecd9c80f329e99b512e8377739/charts/dapr/crds/configuration.yaml

   kubectl replace -f https://raw.githubusercontent.com/dapr/dapr/21636a9237f2dcecd9c80f329e99b512e8377739/charts/dapr/crds/components.yaml

5. Ensure 0.11.x dapr-placement service is still running and wait until 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-operator-5cdd6b7f9c-jkzjs           1/1     Running   0          29s
   dapr-operator-5cdd6b7f9c-qzp8n           1/1     Running   0          34s
   dapr-placement-5dcb574777-nlq4t          1/1     Running   0          76s  <---- 0.11.x placement
   dapr-placement-server-0                  1/1     Running   0          41s
   dapr-placement-server-1                  1/1     Running   0          41s
   dapr-placement-server-2                  1/1     Running   0          41s
   dapr-sentry-84565c747b-7bh8h             1/1     Running   0          35s
   dapr-sentry-84565c747b-fdlls             1/1     Running   0          41s
   dapr-sentry-84565c747b-ldnsf             1/1     Running   0          29s
   dapr-sidecar-injector-68f868668f-6xnbt   1/1     Running   0          41s
   dapr-sidecar-injector-68f868668f-j7jcq   1/1     Running   0          29s
   dapr-sidecar-injector-68f868668f-ltxq4   1/1     Running   0          36s

6. Restart your application deployments to update the Dapr runtime.

   kubectl rollout restart deploy/<DEPLOYMENT-NAME>

7. Once the deployment is completed, delete the 0.11.x dapr-placement service:

   kubectl delete deployment dapr-placement -n dapr-system

   kubectl delete svc dapr-placement -n dapr-system

8. All done!

Upgrade existing cluster running 1.0.0-rc.1

   dapr mtls export -o ./certs

2. Upgrade Dapr to 1.0.0-rc.2:

   helm repo update

   helm upgrade dapr dapr/dapr --version 1.0.0-rc.2 --namespace dapr-system --reset-values --set-file dapr_sentry.tls.root.certPEM=./certs/ca.crt --set-file    dapr_sentry.tls.issuer.certPEM=./certs/issuer.crt --set-file dapr_sentry.tls.issuer.keyPEM=./certs/issuer.key --set global.ha.enabled=true --wait
