Upgrade Dapr on a Kubernetes cluster
Upgrade existing cluster to 1.4.3
There are two ways to upgrade the Dapr control plane on a Kubernetes cluster using either the Dapr CLI or Helm.
The example below shows how to upgrade to version 1.4.3:
dapr upgrade -k --runtime-version=1.4.3
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 1.4.3 -k command as above.
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
--valuesoption 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>
Upgrading existing Dapr to enable high availability mode
Enabling HA mode in an existing Dapr deployment requires additional steps. Please refer to this paragraph for more details.
