Setup Dapr

Dapr can be run in either Standalone or Kubernetes modes. Running Dapr runtime in Standalone 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 Standalone mode and then deploy them to any Kubernetes cluster.

• Prerequsites
• Installing Dapr in standalone mode
• Installing Dapr on Kubernetes cluster

Prerequisites

• Install Docker
• Download the Dapr CLI, unpack it and move it to your desired location.

For Mac/Linux - /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 standalone mode

Install Dapr runtime using the CLI

Install Dapr by running dapr init from a command prompt

For Linux users, if you run your docker cmds with sudo, 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 see that Dapr has been installed successful, from a command prompt run the docker ps command and check that the actionscore.azurecr.io/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 v0.4.0-alpha.4 runtime
$ dapr init --runtime-version v0.4.0-alpha.4

# Check the versions of cli and runtime
$ dapr --version
cli version: v0.2.0-alpha.2
runtime version: v0.4.0-alpha.4

Installing Dapr on a Kubernetes cluster

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

Setup Cluster

• Setup Minikube Cluster
• Setup Azure Kubernetes Service Cluster

Using the Dapr CLI

You can install Dapr to Kubernetes cluster using CLI.

Install Dapr to Kubernetes

$ dapr init --kubernetes
⌛  Making the jump to hyperspace...
✅  Deploying the Dapr Operator to your cluster...
✅  Success! Dapr has been installed. To verify, run 'kubectl get pods' in your terminal.

Dapr CLI installs Dapr to default namespace of Kubernetes cluster.

Uninstall Dapr on Kubernetes

$ dapr uninstall --kubernetes

Using Helm (Advanced)

You can install Dapr to Kubernetes cluster using a Helm chart.

Install Dapr to Kubernetes

1. Make sure Helm is initialized in your running Kubernetes cluster.

2. Add Azure Container Registry as a Helm repo

helm repo add dapr https://actionscore.azurecr.io/helm/v1/repo \
--username 390401a7-d7a6-46da-b10f-3ceff7a1cdd5 \
--password 485b3522-59bb-4152-8938-ca8b90108af6

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

helm install dapr/dapr-operator --name dapr --namespace dapr-system

Verify installation

Once the chart installation is complete, verify the dapr-operator, dapr-placement and dapr-sidecar-injector 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

Uninstall Dapr on Kubernetes

helm del --purge -n dapr

Note: See here for details on Dapr helm charts.
