When setting up Kubernetes you can use either the Dapr CLI or Helm.
|
|
|
|
For more information on what is deployed to your Kubernetes cluster read the [Kubernetes overview]({{< ref kubernetes-overview.md >}})
|
|
|
|
## Prerequisites
|
|
|
|
- Install [Dapr CLI]({{< ref install-dapr-cli.md >}})
|
|
- Install [kubectl](https://kubernetes.io/docs/tasks/tools/)
|
|
- Kubernetes cluster (see below if needed)
|
|
|
|
### Create cluster
|
|
|
|
You can install Dapr on any Kubernetes cluster. Here are some helpful links:
|
|
|
|
- [Setup Minikube Cluster]({{< ref setup-minikube.md >}})
|
|
- [Setup Azure Kubernetes Service Cluster]({{< ref setup-aks.md >}})
|
|
- [Setup Google Cloud Kubernetes Engine](https://cloud.google.com/kubernetes-engine/docs/quickstart)
|
|
- [Setup Amazon Elastic Kubernetes Service](https://docs.aws.amazon.com/eks/latest/userguide/getting-started.html)

{{% alert title="Hybrid clusters" color="primary" %}}
|
|
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]({{<ref kubernetes-hybrid-clusters>}}).

|
## Install with Dapr CLI
|
|
|
|
You can install Dapr to a Kubernetes cluster using the [Dapr CLI]({{< ref install-dapr-cli.md >}}).
|
|
|
|
### Install Dapr
|
|
|
|
The `-k` flag initializes Dapr on the Kubernetes cluster in your current context.
|
|
|
|
{{% alert title="Ensure correct cluster is set" color="warning" %}}
|
|
Make sure the correct "target" cluster is set. Check `kubectl context (kubectl config get-contexts)` to verify. You can set a different context using `kubectl config use-context <CONTEXT>`.
|
|
{{% /alert %}}
|
|
|
|
Run the following command on your local machine to init Dapr on your cluster:
|
|
|
|
```bash
|
|
dapr init -k
|
|
```
|
|
|
|
```bash
|
|
⌛ Making the jump to hyperspace...
|
|
|
|
✅ Deploying the Dapr control plane to your cluster...
|
|
✅ 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.
|
|
|
|
```bash
|
|
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]({{< ref kubernetes-production.md >}}).
|
|
|
|
```bash
|
|
dapr init -k --enable-ha=true
|
|
```
|
|
|
|
### Disable mTLS
|
|
|
|
Dapr is initialized by default with [mTLS]({{< ref "security-concept.md#sidecar-to-sidecar-communication" >}}). You can disable it with:
|
|
|
|
```bash
|
|
dapr init -k --enable-mtls=false
|
|
```
|
|
|
|
### Wait for the installation to complete
|
|
|
|
You can wait for the installation to complete its deployment with the `--wait` flag.
|
|
|
|
The default timeout is 300s (5 min), but can be customized with the `--timeout` flag.
|
|
|
|
```bash
|
|
dapr init -k --wait --timeout 600
|
|
```
|
|
|
|
### Uninstall Dapr on Kubernetes with CLI
|
|
|
|
Run the following command on your local machine to uninstall Dapr on your cluster:
|
|
|
|
```bash
|
|
dapr uninstall -k
|
|
```
|
|
|
|
## Install with Helm (advanced)
|
|
|
|
You can install Dapr on Kubernetes using a Helm 3 chart.
|
|
|
|
{{% alert title="Ensure you are on Helm v3" color="primary" %}}
|
|
The latest Dapr helm chart no longer supports Helm v2. Please migrate from Helm v2 to Helm v3 by following [this guide](https://helm.sh/blog/migrate-from-helm-v2-to-helm-v3/).
|
|
{{% /alert %}}
|
|
|
|
### Add and install Dapr Helm chart
|
|
|
|
1. Make sure [Helm 3](https://github.com/helm/helm/releases) is installed on your machine
|
|
2. Add Helm repo and update
|
|
|
|
```bash
|
|
helm repo add dapr https://dapr.github.io/helm-charts/
|
|
helm repo update
|
|
# See which chart versions are available
|
|
helm search repo dapr --devel --versions
|
|
```
|
|
3. Install the Dapr chart on your cluster in the `dapr-system` namespace.
|
|
|
|
```bash
|
|
helm upgrade --install dapr dapr/dapr \
|
|
--version={{% dapr-latest-version short="true" %}} \
|
|
--namespace dapr-system \
|
|
--create-namespace \
|
|
--wait
|
|
```
|
|
|
|
To install in high availability mode:
|
|
|
|
```bash
|
|
helm upgrade --install dapr dapr/dapr \
|
|
--version={{% dapr-latest-version short="true" %}} \
|
|
--namespace dapr-system \
|
|
--create-namespace \
|
|
--set global.ha.enabled=true \
|
|
--wait
|
|
```
|
|
|
|
|
|
See [Guidelines for production ready deployments on Kubernetes]({{<ref kubernetes-production.md>}}) for more information on installing and upgrading Dapr using Helm.
|
|
|
|
### Uninstall Dapr on Kubernetes
|
|
|
|
```bash
|
|
helm uninstall dapr --namespace dapr-system
|
|
```
|
|
|
|
### More information
|
|
|
|
- Read [this guide]({{< ref kubernetes-production.md >}}) for recommended Helm chart values for production setups
|
|
- See [this page](https://github.com/dapr/dapr/blob/master/charts/dapr/README.md) for details on Dapr Helm charts.
|
|
|
|
## Verify installation
|
|
|
|
Once the installation is complete, verify that the dapr-operator, dapr-placement, dapr-sidecar-injector and dapr-sentry pods are running in the `dapr-system` namespace:
|
|
|
|
```bash
|
|
kubectl get pods --namespace dapr-system
|
|
```
|
|
|
|
```bash
|
|
