Deploy Dapr on a Kubernetes cluster

Follow these steps to deploy Dapr on Kubernetes.

When setting up Kubernetes you can use either the Dapr CLI or Helm.

As part of the Dapr initialization the following pods are installed:

  • 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
  • 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

前期准备

Create cluster

You can install Dapr on any Kubernetes cluster. Here are some helpful links:

Hybrid clusters

Both the Dapr CLI and the Dapr Helm chart automatically deploy with affinity for nodes with the label kubernetes.io/os=linux. You can deploy Dapr to Windows nodes if your application requires it. For more information see Deploying to a hybrid Linux/Windows Kubernetes cluster.

Install with Dapr CLI

You can install Dapr to a Kubernetes cluster using the Dapr CLI.

Install Dapr

The -k flag initializes Dapr on the Kubernetes cluster in your current context.

Target cluster

Make sure the correct “target” cluster is set. Check kubectl context (kubectl config kubectl config get-contexts) to verify. You can set a different context using kubectl config use-context <CONTEXT>.

Run on your local machine:

  1. dapr init -k
  1. ⌛  Making the jump to hyperspace...
  2. ℹ️  Note: To install Dapr using Helm, see here:  https://github.com/dapr/docs/blob/master/getting-started/environment-setup.md#using-helm-advanced
  4. ✅  Deploying the Dapr control plane to your cluster...
  5. ✅  Success! Dapr has been installed to namespace dapr-system. To verify, run "dapr status -k" in your terminal. To get started, go here: https://aka.ms/dapr-getting-started

Install in custom namespace

The default namespace when initializing Dapr is dapr-system. You can override this with the -n flag.

  1. dapr init -k -n mynamespace

Install in highly available mode:

You can run Dapr with 3 replicas of each control plane pod in the dapr-system namespace for production scenarios.

  1. dapr init -k --enable-ha=true

Disable mTLS

Dapr is initialized by default with mTLS. You can disable it with:

  1. dapr init -k --enable-mtls=false

Uninstall Dapr on Kubernetes with CLI

  1. dapr uninstall --kubernetes

Upgrade Dapr on a cluster

To upgrade Dapr on a Kubernetes cluster you can use the CLI. See upgrade Dapr on Kubernetes for more information.

Install with Helm (advanced)

You can install Dapr on Kubernetes using a Helm 3 chart.

Note

The latest Dapr helm chart no longer supports Helm v2. Please migrate from Helm v2 to Helm v3 by following this guide.

Add and install Dapr Helm chart

  1. Make sure Helm 3 is installed on your machine

  2. Add Helm repo and update

    1. helm repo add dapr https://dapr.github.io/helm-charts/
    2. helm repo update
    3. # See which chart versions are available
    4. helm search repo dapr --devel --versions

  3. Install the Dapr chart on your cluster in the dapr-system namespace.

    1. helm upgrade --install dapr dapr/dapr \
    2. --version=1.0.0 \
    3. --namespace dapr-system \
    4. --create-namespace \
    5. --wait

To install in high availability mode:

  1. ```bash
  2. helm upgrade --install dapr dapr/dapr \
  3. --version=1.0.0 \
  4. --namespace dapr-system \
  5. --create-namespace \
  6. --set global.ha.enabled=true \
  7. --wait
  8. ```

See Guidelines for production ready deployments on Kubernetes for more information on installing and upgrading Dapr using Helm.

Verify installation

Once the chart installation is complete, verify that the dapr-operator, dapr-placement, dapr-sidecar-injector and dapr-sentry pods are running in the dapr-system namespace:

  1. kubectl get pods --namespace dapr-system
  1. NAME                                     READY     STATUS    RESTARTS   AGE
  2. dapr-dashboard-7bd6cbf5bf-xglsr          1/1       Running   0          40s
  3. dapr-operator-7bd6cbf5bf-xglsr           1/1       Running   0          40s
  4. dapr-placement-7f8f76778f-6vhl2          1/1       Running   0          40s
  5. dapr-sidecar-injector-8555576b6f-29cqm   1/1       Running   0          40s
  6. dapr-sentry-9435776c7f-8f7yd             1/1       Running   0          40s

Uninstall Dapr on Kubernetes

  1. helm uninstall dapr --namespace dapr-system
