Environment Setup

Dapr can be run in either self hosted or Kubernetes modes. Running Dapr runtime in self hosted mode enables you to develop Dapr applications in your local development environment and then deploy and run them in other Dapr supported environments. For example, you can develop Dapr applications in self hosted mode and then deploy them to any Kubernetes cluster.

Contents

Prerequisites

On default Dapr will install with a developer environment using Docker containers to get you started easily. However, Dapr does not depend on Docker to run (see here for instructions on installing Dapr locally without Docker using slim init). This getting started guide assumes Dapr is installed along with this developer environment.

For Windows user, ensure that Docker Desktop For Windows uses Linux containers.

Installing Dapr CLI

Using script to install the latest release

Windows

Install the latest windows Dapr cli to c:\dapr and add this directory to User PATH environment variable.

powershell -Command "iwr -useb https://raw.githubusercontent.com/dapr/cli/master/install/install.ps1 | iex"

Linux

Install the latest linux Dapr CLI to /usr/local/bin

wget -q https://raw.githubusercontent.com/dapr/cli/master/install/install.sh -O - | /bin/bash

MacOS

Install the latest darwin Dapr CLI to /usr/local/bin

curl -fsSL https://raw.githubusercontent.com/dapr/cli/master/install/install.sh | /bin/bash

Or install via Homebrew

brew install dapr/tap/dapr-cli

From the Binary Releases

Each release of Dapr CLI includes various OSes and architectures. These binary versions can be manually downloaded and installed.

  1. Download the Dapr CLI
  2. Unpack it (e.g. dapr_linux_amd64.tar.gz, dapr_windows_amd64.zip)
  3. Move it to your desired location.
    • For Linux/MacOS - /usr/local/bin
    • For Windows, create a directory and add this to your System PATH. For example create a directory called c:\dapr and add this directory to your path, by editing your system environment variable.

Installing Dapr in self hosted mode

Initialize Dapr using the CLI

On default, during initialization the Dapr CLI will install the Dapr binaries as well as setup a developer environment to help you get started easily with Dapr. This environment uses Docker containers, therefore Docker is listed as a prerequisite.

If you prefer to run Dapr without this environment and no dependency on Docker, see the CLI documentation for usage of the --slim flag with the init CLI command here. Note, if you are a new user, it is strongly recommended to intall Docker and use the regular init command.

For Linux users, if you run your docker cmds with sudo or the install path is /usr/local/bin(default install path), you need to use "sudo dapr init" For Windows users, make sure that you run the cmd terminal in administrator mode Note: See Dapr CLI for details on the usage of Dapr CLI

$ dapr init
⌛  Making the jump to hyperspace...
Downloading binaries and setting up components
✅  Success! Dapr is up and running. To get started, go here: https://aka.ms/dapr-getting-started

If you prefer you can also install to an alternate location by using --install-path:

$ dapr init --install-path /home/user123/mydaprinstall

To see that Dapr has been installed successfully, from a command prompt run the docker ps command and check that the daprio/dapr:latest and redis container images are both running.

Install a specific runtime version

You can install or upgrade to a specific version of the Dapr runtime using dapr init --runtime-version. You can find the list of versions in Dapr Release.

# Install v0.1.0 runtime
$ dapr init --runtime-version 0.1.0

# Check the versions of cli and runtime
$ dapr --version
cli version: v0.1.0
runtime version: v0.1.0

Uninstall Dapr in a self hosted mode

Uninstalling removes the Placement service container or the Placement service binary.

$ dapr uninstall

For Linux users, if you run your docker cmds with sudo or the install path is /usr/local/bin(default install path), you need to use "sudo dapr uninstall" to remove dapr binaries and/or the containers.

It won't remove the Redis or Zipkin containers by default in case you were using them for other purposes. To remove Redis, Zipkin and actor Placement container as well as remove the default Dapr dir located at $HOME/.dapr or %USERPROFILE%\.dapr\ run:

$ dapr uninstall --all

You should always run dapr uninstall before running another dapr init.

To specify a custom install path from which you have to uninstall run:

$ dapr uninstall --install-path /path/to/binary

Installing Dapr on a Kubernetes cluster

When setting up Kubernetes, you can do this either via the Dapr CLI or Helm.

Dapr installs the following pods:

  • 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

Setup Cluster

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

Note: The Dapr control plane containers are currently only distributed on linux containers. Your Kubernetes cluster must contain available Linux capable nodes. Both the Dapr CLI, and the Dapr Helm chart automatically deploy with affinity for nodes with the label kubernetes.io/os=linux. For more information see Deploying to a Hybrid Linux/Windows K8s Cluster

Using the Dapr CLI

You can install Dapr to a Kubernetes cluster using CLI.

Install Dapr to Kubernetes

Note: The default namespace is dapr-system

$ dapr init -k

⌛  Making the jump to hyperspace...
ℹ️  Note: To install Dapr using Helm, see here:  https://github.com/dapr/docs/blob/master/getting-started/environment-setup.md#using-helm-advanced

✅  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 to a custom namespace:

dapr init -k -n mynamespace

Installing in highly available mode:

dapr init -k --enable-ha=true

Disable mTLS:

dapr init -k --enable-mtls=false

Uninstall Dapr on Kubernetes

$ dapr uninstall --kubernetes

Using Helm (Advanced)

You can install Dapr to Kubernetes cluster 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.

Install Dapr to Kubernetes

  1. Make sure Helm 3 is installed on your machine

  2. Add Azure Container Registry as a Helm repo

helm repo add dapr https://daprio.azurecr.io/helm/v1/repo
helm repo update
  1. Create dapr-system namespace on your kubernetes cluster
kubectl create namespace dapr-system
  1. Install the Dapr chart on your cluster in the dapr-system namespace.
helm install dapr dapr/dapr --namespace dapr-system

Verify installation

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

$ kubectl get pods -n dapr-system -w

NAME                                     READY     STATUS    RESTARTS   AGE
dapr-operator-7bd6cbf5bf-xglsr           1/1       Running   0          40s
dapr-placement-7f8f76778f-6vhl2          1/1       Running   0          40s
dapr-sidecar-injector-8555576b6f-29cqm   1/1       Running   0          40s
dapr-sentry-9435776c7f-8f7yd             1/1       Running   0          40s
