Supported platforms

Usage

dapr init [flags]

Flags

Name Environment Variable Default Description
--dashboard-version latest The version of the Dapr dashboard to install, for example: 1.0.0
--enable-ha false Enable high availability (HA) mode
--enable-mtls true Enable mTLS in your cluster
--from-dir Path to a local directory containing a downloaded “Dapr Installer Bundle” release which is used to init the airgap environment
--help, -h Print this help message
--image-registry Pulls container images required by Dapr from the given image registry
--kubernetes, -k false Deploy Dapr to a Kubernetes cluster
--namespace, -n dapr-system The Kubernetes namespace to install Dapr in
--network The Docker network on which to install and deploy the Dapr runtime
--runtime-version latest The version of the Dapr runtime to install, for example: 1.0.0
--image-variant The image variant to use for the Dapr runtime, for example: mariner
--set Configure options on the command line to be passed to the Dapr Helm chart and the Kubernetes cluster upon install. Can specify multiple values in a comma-separated list, for example: key1=val1,key2=val2
--slim, -s false Exclude placement service, Redis and Zipkin containers from self-hosted installation
--timeout 300 The wait timeout for the Kubernetes installation
--wait false Wait for Kubernetes initialization to complete
N/A DAPR_DEFAULT_IMAGE_REGISTRY It is used to specify the default container registry to pull images from. When its value is set to GHCR or ghcr it pulls the required images from Github container registry. To default to Docker hub, unset the environment variable or leave it blank
N/A DAPR_HELM_REPO_URL Specifies a private Dapr Helm chart url
N/A DAPR_HELM_REPO_USERNAME A username for a private Helm chart The username required to access the private Dapr Helm chart. If it can be accessed publicly, this env variable does not need to be set
N/A DAPR_HELM_REPO_PASSWORD A password for a private Helm chart The password required to access the private Dapr Helm chart. If it can be accessed publicly, this env variable does not need to be set
--container-runtime docker Used to pass in a different container runtime other than Docker. Supported container runtimes are: docker, podman
--dev Creates Redis and Zipkin deployments when run in Kubernetes.

Examples


Install

Install Dapr by pulling container images for Placement, Redis, and Zipkin. By default, these images are pulled from Docker Hub.

dapr init

Dapr can also run Slim self-hosted mode, without Docker.

dapr init -s

To switch to Dapr Github container registry as the default registry, set the DAPR_DEFAULT_IMAGE_REGISTRY environment variable value to be GHCR. To switch back to Docker Hub as default registry, unset this environment variable.

Specify a runtime version

You can also specify a specific runtime version. Be default, the latest version is used.

dapr init --runtime-version 1.13.0

Install with image variant

You can also install Dapr with a particular image variant, for example: mariner.

dapr init --image-variant mariner

Use Dapr Installer Bundle

In an offline or airgap environment, you can download a Dapr Installer Bundle and use this to install Dapr instead of pulling images from the network.

dapr init --from-dir <path-to-installer-bundle-directory>

Dapr can also run in slim self-hosted mode without Docker in an airgap environment.

dapr init -s --from-dir <path-to-installer-bundle-directory>

Specify private registry

You can also specify a private registry to pull container images from. These images need to be published to private registries as shown below to enable Dapr CLI to pull them successfully via the dapr init command:

  1. Dapr runtime container image(dapr) (Used to run Placement) - dapr/dapr:
  2. Redis container image(rejson) - dapr/3rdparty/rejson
  3. Zipkin container image(zipkin) - dapr/3rdparty/zipkin

All the required images used by Dapr needs to be under the dapr path. The 3rd party images have to be published under dapr/3rdparty path.

image-registry uri follows the docker.io/<username> format.

dapr init --image-registry docker.io/username

This command resolves the complete image URI as shown below -

  1. Placement container image(dapr) - docker.io/username/dapr/dapr:
  2. Redis container image(rejson) - docker.io/username/dapr/3rdparty/rejson
  3. zipkin container image(zipkin) - docker.io/username/dapr/3rdparty/zipkin

You can specify a different container runtime while setting up Dapr. If you omit the --container-runtime flag, the default container runtime is Docker.

dapr init --container-runtime podman

Use Docker network

You can deploy local containers into Docker networks, which is useful for deploying into separate networks or when using Docker Compose for local development to deploy applications.

Create the Docker network.

docker network create mynet

Initialize Dapr and specify the created Docker network.

dapr init --network mynet

Verify all containers are running in the specified network.

docker ps 

Uninstall Dapr from that Docker network.

dapr uninstall --all --network mynet

dapr init -k

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.

dapr init -k --wait --timeout 600

You can also specify a specific runtime version.

dapr init -k --runtime-version 1.4.0

Use the --set flag to configure a set of Helm Chart values during Dapr installation to help set up a Kubernetes cluster.

dapr init -k --set global.tag=1.0.0 --set dapr_operator.logLevel=error

You can also specify a private registry to pull container images from. As of now dapr init -k does not use specific images for sentry, operator, placement and sidecar. It relies on only Dapr runtime container image dapr for all these images.

Scenario 1 : dapr image hosted directly under root folder in private registry -

dapr init -k --image-registry docker.io/username

Scenario 2 : dapr image hosted under a new/different directory in private registry -

dapr init -k --image-registry docker.io/username/<directory-name>
