||
| This how-to guide will provide an overview of how to: | ||
|
|
||
| - Securely manage secrets in Dapr components using [Dapr secret stores](https://docs.dapr.io/operations/components/setup-secret-store/) | ||
|
|
||
| ## Prerequisites | ||
|
|
||
| - [rad CLI]({{< ref "installation#step-1-install-the-rad-cli" >}}) | ||
| - [Bicep VSCode extension]({{< ref "installation#step-2-install-the-vs-code-extension" >}}) | ||
| - [Radius environment]({{< ref "installation#step-3-initialize-radius" >}}) | ||
| - [Radius local-dev Recipes]({{< ref howto-dev-recipes >}}) | ||
| - [Dapr installed on your Kubernetes cluster](https://docs.dapr.io/operations/hosting/kubernetes/kubernetes-deploy/) | ||
|
|
||
| ## Step 1: Start with a container and a Dapr sidecar | ||
|
|
||
| Begin by creating a file named app.bicep, which defines a container with a Dapr state store. If you need a detailled explanation on how to do so, refer to the [Add a Dapr building block]({{< ref how-to-dapr-building-block >}}) tutorial. | ||
|
|
||
| For this guide, we'll manually provision both a Redis instance and a Dapr State store component. This allows us to specify the Redis username in the Dapr state store, which we will later secure using a Dapr secret store. | ||
|
|
||
| {{< rad file="./snippets/app-statestore.bicep" embed=true >}} | ||
|
|
||
| Deploy the application with the `rad` CLI: | ||
|
|
||
| ```bash | ||
| rad run ./app.bicep -a demo-secret | ||
| ``` | ||
|
|
||
| While the application is running, verify that the `redisUsername` is exposed in the Dapr state store component by running the following command **in another terminal**: | ||
| ```sh | ||
| kubectl -n default-demo-secret get component demo-statestore -o yaml | ||
| ``` | ||
|
|
||
| The output should look similar to: | ||
| ```yaml | ||
| apiVersion: dapr.io/v1alpha1 | ||
| kind: Component | ||
| metadata: | ||
| name: demo-statestore | ||
| namespace: default-demo-secret | ||
| spec: | ||
| metadata: | ||
| - name: redisHost | ||
| value: <HOST> | ||
| - name: redisUsername | ||
| # The Redis username is stored in plain text | ||
| value: default | ||
| type: state.redis | ||
| version: v1 | ||
| ``` | ||
| ## Step 2: Add a Dapr secret store resource and create a secret | ||
| Next, we'll secure the Redis username using a Dapr secret store. In your `app.bicep` file, add a Dapr secret store resource. We'll use the [`local-dev` recipe]({{< ref "guides/recipes/overview##use-lightweight-local-dev-recipes" >}}) to deploy the secret store, which will leverage Kubernetes secrets. | ||
|
|
||
| {{< rad file="./snippets/app-statestore-secret.bicep" embed=true marker="//SECRETSTORE" >}} | ||
|
|
||
| > Visit the [Radius Recipe repo](https://github.com/radius-project/recipes/blob/main/local-dev/secretstores.bicep) to learn more about `local-dev` Recipes and view the Dapr Secret Store Recipe used in this guide. | ||
|
|
||
|
|
||
| Now, create a Kubernetes secret for the Redis username by creating a `redis-auth.yaml` file with the following content: | ||
| ```yaml | ||
| apiVersion: v1 | ||
| kind: Secret | ||
| metadata: | ||
| name: redis-auth | ||
| namespace: default-demo-secret | ||
| type: opaque | ||
| data: | ||
| # Result of "echo -n 'default' | base64" | ||
| username: ZGVmYXVsdA== | ||
| ``` | ||
|
|
||
| Apply the secret to your Kubernetes cluster by running: | ||
| ```sh | ||
| kubectl apply -f redis-auth.yaml | ||
| ``` | ||
|
|
||
| ## Step 3: Configure the Dapr state store to use the Dapr secret store | ||
|
|
||
| Finally, update your Dapr state store to reference the created secret. | ||
|
|
||
| {{< rad file="./snippets/app-statestore-secret.bicep" embed=true marker="//STATESTORE" >}} | ||
|
|
||
|
|
||
| ## Step 4: Deploy the updated application | ||
|
|
||
| Deploy the application with the updated configuration: | ||
| ```bash | ||
| rad run ./app.bicep -a demo-secret | ||
| ``` | ||
|
|
||
| You can verify that the Redis username is no longer exposed by running the following command **in another terminal**: | ||
| ```sh | ||
| kubectl -n default-demo-secret get component demo-statestore -o yaml | ||
| ``` | ||
|
|
||
| The output should show the Redis username stored in the secret store: | ||
| ```yaml | ||
| apiVersion: dapr.io/v1alpha1 | ||
| auth: | ||
| secretStore: secretstore | ||
| kind: Component | ||
| metadata: | ||
| name: demo-statestore | ||
| namespace: default-demo-secret | ||
| spec: | ||
| metadata: | ||
| - name: redisHost | ||
| value: <HOST> | ||
| - name: redisUsername | ||
| secretKeyRef: | ||
| key: username | ||
| name: redis-auth | ||
| type: state.redis | ||
| version: v1 | ||
| ``` | ||
| Open [http://localhost:3000](http://localhost:3000) to view the Radius demo container. The TODO application should work as intended. | ||
|
|
||
| > In a production environment, it's recommended to use a more secure secret store, such as Azure Key Vault or HashiCorp Vault, instead of relying on Kubernetes secrets. You can find the list of all Dapr secret store components [here](https://docs.dapr.io/reference/components-reference/supported-secret-stores/). | ||
|
|
||
| ## Cleanup | ||
|
|
||
| To delete your app, run the [rad app delete]({{< ref rad_application_delete >}}) command to cleanup the app and its resources, including the Recipe resources: | ||
|
|
||
| ```bash | ||
| rad app delete -a demo-secret | ||
| kubectl delete secret redis-auth -n default-demo-secret | ||
| ``` | ||
|
