Install the Dapr extension for Azure Kubernetes Service (AKS) and Arc-enabled Kubernetes
Dapr simplifies building resilient, stateless, and stateful applications that run on the cloud and edge and embrace the diversity of languages and developer frameworks. With Dapr's sidecar architecture, you can keep your code platform agnostic while tackling challenges around building microservices, like:
- Calling other services reliably and securely
- Building event-driven apps with pub/sub
- Building applications that are portable across multiple cloud services and hosts (for example, Kubernetes vs. a virtual machine)
Note
If you plan on installing Dapr in a Kubernetes production environment, see the Dapr guidelines for production usage documentation page.
How it works
The Dapr extension uses the Azure CLI or a Bicep template to provision the Dapr control plane on your AKS or Arc-enabled Kubernetes cluster, creating the following Dapr services:
Dapr service | Description |
---|---|
dapr-operator |
Manages component updates and Kubernetes services endpoints for Dapr (state stores, pub/subs, etc.) |
dapr-sidecar-injector |
Injects Dapr into annotated deployment pods and adds the environment variables DAPR_HTTP_PORT and DAPR_GRPC_PORT to enable user-defined applications to easily communicate with Dapr without hard-coding Dapr port values. |
dapr-placement |
Used for actors only. Creates mapping tables that map actor instances to pods. |
dapr-sentry |
Manages mTLS between services and acts as a certificate authority. For more information, read the security overview. |
Once Dapr is installed on your cluster, you can begin to develop using the Dapr building block APIs by adding a few annotations to your deployments. For a more in-depth overview of the building block APIs and how to best use them, see the Dapr building blocks overview.
Warning
If you install Dapr through the AKS or Arc-enabled Kubernetes extension, our recommendation is to continue using the extension for future management of Dapr instead of the Dapr CLI. Combining the two tools can cause conflicts and result in undesired behavior.
Prerequisites
- An Azure subscription. Don't have one? Create a free account.
- The latest version of the Azure CLI.
- An existing AKS cluster or connected Arc-enabled Kubernetes cluster.
- An Azure Kubernetes Service Role-Based Access Control Admin role
Select how you'd like to install, deploy, and configure the Dapr extension.
Before you begin
Add the Azure CLI extension for cluster extensions
Install the k8s-extension
Azure CLI extension by running the following commands:
az extension add --name k8s-extension
If the k8s-extension
extension is already installed, you can update it to the latest version using the following command:
az extension update --name k8s-extension
Register the KubernetesConfiguration
resource provider
If you aren't already using cluster extensions, you may need to register the resource provider with your subscription. You can check the status of the provider registration using the az provider list command, as shown in the following example:
az provider list --query "[?contains(namespace,'Microsoft.KubernetesConfiguration')]" -o table
The Microsoft.KubernetesConfiguration provider should report as Registered, as shown in the following example output:
Namespace RegistrationState RegistrationPolicy
--------------------------------- ------------------- --------------------
Microsoft.KubernetesConfiguration Registered RegistrationRequired
If the provider shows as NotRegistered, register the provider using the az provider register as shown in the following example:
az provider register --namespace Microsoft.KubernetesConfiguration
Register the ExtenstionTypes
feature to your Azure subscription
The ExtensionTypes
feature needs to be registered to your Azure subscription. In the terminal, verify you're in the correct subscription:
az account set --subscription <YOUR-AZURE-SUBSCRIPTION-ID>
Register the ExtenstionTypes
feature.
az feature registration create --namespace Microsoft.KubernetesConfiguration --name ExtensionTypes
Feature registration may take some time. After a few minutes, check the registration status using the following command:
az feature show --namespace Microsoft.KubernetesConfiguration --name ExtensionTypes
Create the extension and install Dapr on your AKS or Arc-enabled Kubernetes cluster
When installing the Dapr extension, use the flag value that corresponds to your cluster type:
- AKS cluster:
--cluster-type managedClusters
. - Arc-enabled Kubernetes cluster:
--cluster-type connectedClusters
.
Note
If you're using Dapr OSS on your AKS cluster and would like to install the Dapr extension for AKS, read more about how to successfully migrate to the Dapr extension.
Create the Dapr extension, which installs Dapr on your AKS or Arc-enabled Kubernetes cluster.
For example, install the latest version of Dapr via the Dapr extension on your AKS cluster:
az k8s-extension create --cluster-type managedClusters \
--cluster-name <myAKSCluster> \
--resource-group <myResourceGroup> \
--name dapr \
--extension-type Microsoft.Dapr \
--auto-upgrade-minor-version false
Keep your managed AKS cluster updated to the latest version
Based on your environment (dev, test, or production), you can keep up-to-date with the latest stable Dapr versions.
Choosing a release train
When configuring the extension, you can choose to install Dapr from a particular release train. Specify one of the two release train values:
Value | Description |
---|---|
stable |
Default. |
dev |
Early releases that can contain experimental features. Not suitable for production. |
For example:
--release-train stable
Configuring automatic updates to Dapr control plane
Warning
Auto-upgrade is not suitable for production environments. Only enable automatic updates to the Dapr control plane in dev or test environments. Learn how to manually upgrade to the latest Dapr version for production environments.
If you install Dapr without specifying a version, --auto-upgrade-minor-version
is automatically enabled, configuring the Dapr control plane to automatically update its minor version on new releases.
You can disable auto-update by specifying the --auto-upgrade-minor-version
parameter and setting the value to false
.
Dapr versioning is in MAJOR.MINOR.PATCH
format, which means 1.11.0
to 1.12.0
is a minor version upgrade.
--auto-upgrade-minor-version true
Viewing the latest stable Dapr versions available
To upgrade to the latest Dapr version in a production environment, you need to manually upgrade. Start by viewing a list of the stable Dapr versions available to your managed AKS cluster. Run the following command:
az k8s-extension extension-types list-versions-by-cluster --resource-group <myResourceGroup> --cluster-name <myCluster> --cluster-type managedClusters --extension-type microsoft.dapr --release-train stable
To see the latest stable Dapr version available to your managed AKS cluster, run the following command:
az k8s-extension extension-types list-versions-by-cluster --resource-group <myResourceGroup> --cluster-name <myCluster> --cluster-type managedClusters --extension-type microsoft.dapr --release-train stable --show-latest
To view a list of the stable Dapr versions available by location:
- Make sure you've registered the
ExtenstionTypes
feature to your Azure subscription. - Run the following command.
az k8s-extension extension-types list-versions-by-location --location westus --extension-type microsoft.dapr
Next, manually update Dapr to the latest stable version.
Targeting a specific Dapr version
Note
Dapr is supported with a rolling window, including only the current and previous versions. It is your operational responsibility to remain up to date with these supported versions. If you have an older version of Dapr, you may have to do intermediate upgrades to get to a supported version.
The same command-line argument is used for installing a specific version of Dapr or rolling back to a previous version. Set --auto-upgrade-minor-version
to false
and --version
to the version of Dapr you wish to install. If the version
parameter is omitted, the extension installs the latest version of Dapr. For example, to use Dapr 1.13.5:
az k8s-extension create --cluster-type managedClusters \
--cluster-name <myAKSCluster> \
--resource-group <myResourceGroup> \
--name dapr \
--extension-type Microsoft.Dapr \
--auto-upgrade-minor-version false \
--version 1.13.5
Troubleshooting extension errors
If the extension fails to create or update, try suggestions and solutions in the Dapr extension troubleshooting guide.
Troubleshooting Dapr
Troubleshoot Dapr errors via the common Dapr issues and solutions guide.
Delete the extension
If you need to delete the extension and remove Dapr from your AKS cluster, you can use the following command:
az k8s-extension delete --resource-group <myResourceGroup> --cluster-name <myAKSCluster> --cluster-type managedClusters --name dapr
Or you can remove the Bicep template.
