Upgrade Dapr on a Kubernetes cluster
Upgrade existing cluster to 1.9.5
There are two ways to upgrade the Dapr control plane on a Kubernetes cluster using either the Dapr CLI or Helm.
NoteRefer to the Dapr version policy for guidance on which versions of Dapr can be upgraded to which versions.
The example below shows how to upgrade to version 1.9.5:
dapr upgrade -k --runtime-version=1.9.5
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 1.9.5 -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] > 1.0.0:
Helm does not handle upgrading CRDs, so you need to perform that manually. CRDs are backward-compatible and should only be installed forward.
Note: The Dapr version is included in the commands below.
For version 1.9.5:
kubectl replace -f https://raw.githubusercontent.com/dapr/dapr/v1.9.5/charts/dapr/crds/components.yaml kubectl replace -f https://raw.githubusercontent.com/dapr/dapr/v1.9.5/charts/dapr/crds/configuration.yaml kubectl replace -f https://raw.githubusercontent.com/dapr/dapr/v1.9.5/charts/dapr/crds/subscription.yaml kubectl apply -f https://raw.githubusercontent.com/dapr/dapr/v1.9.5/charts/dapr/crds/resiliency.yaml
helm repo update
helm upgrade dapr dapr/dapr --version 1.9.5 --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.
