By default, Dapr relies on the network boundary to limit access to its public API. If you plan on exposing the Dapr API outside of that boundary, or if your deployment demands an additional level of security, consider enabling the token authentication for Dapr APIs. This will cause Dapr to require every incoming gRPC and HTTP request for its APIs for to include authentication token, before allowing that request to pass through.

## Accessing the token from the app
|
||||
|
||||
### Kubernetes
|
||||
|
||||
In Kubernetes, it's recommended to mount the secret to your pod as an environment variable, as shown in the example below, where a Kubernetes secret with the name `dapr-api-token` is used to hold the token.
|
||||
|
||||
```
|
||||
containers:
|
||||
- name: mycontainer
|
||||
image: myregistry/myapp
|
||||
envFrom:
|
||||
- secretRef:
|
||||
name: dapr-api-token
|
||||
```
|
||||
|
||||
### Self-hosted
|
||||
|
||||
In self-hosted mode, you can set the token as an environment variable for your app:
|
||||
|
||||
```
|
||||
export DAPR_API_TOKEN=<my-dapr-token>
|
||||
```

|
||||
For some building blocks such as pub/sub, service invocation and input bindings, Dapr communicates with an app over HTTP or gRPC.
|
||||
To enable the application to authenticate requests that are arriving from the Dapr sidecar, you can configure Dapr to send an API token as a header (in HTTP requests) or metadata (in gRPC requests).
|
||||
|
||||
## Create a token
|
||||
|
||||
Dapr uses [JWT](https://jwt.io/) tokens for API authentication.
|
||||
|
||||
> Note, while Dapr itself is actually not the JWT token issuer in this implementation, being explicit about the use of JWT standard enables federated implementations in the future (e.g. OAuth2).
|
||||
|
||||
To configure API authentication, start by generating your token using any JWT token compatible tool (e.g. https://jwt.io/) and your secret.
|
||||
|
||||
> Note, that secret is only necessary to generate the token, and Dapr doesn't need to know about or store it
|
||||
|
||||
## Configure app API token authentication in Dapr
|
||||
|
||||
The token authentication configuration is slightly different for either Kubernetes or self-hosted Dapr deployments:
|
||||
|
||||
### Self-hosted
|
||||
|
||||
In self-hosting scenario, Dapr looks for the presence of `APP_API_TOKEN` environment variable. If that environment variable is set while `daprd` process launches, Dapr includes the token when calling an app:
|
||||
|
||||
```shell
|
||||
export APP_API_TOKEN=<token>
|
||||
```
|
||||
|
||||
To rotate the configured token, simply set the `APP_API_TOKEN` environment variable to the new value and restart the `daprd` process.
|
||||
|
||||
### Kubernetes
|
||||
|
||||
In Kubernetes deployment, Dapr leverages Kubernetes secrets store to hold the JWT token. Start by creating a new secret:
|
||||
|
||||
```shell
|
||||
kubectl create secret generic app-api-token --from-literal=token=<token>
|
||||
```
|
||||
|
||||
> Note, the above secret needs to be created in each namespace in which you want to enable app token authentication
|
||||
|
||||
To indicate to Dapr to use the token in the secret when sending requests to the app, add an annotation to your Deployment template spec:
|
||||
|
||||
```yaml
|
||||
annotations:
|
||||
dapr.io/enabled: "true"
|
||||
dapr.io/app-token-secret: "app-api-token" # name of the Kubernetes secret
|
||||
```
|
||||
|
||||
When deployed, the Dapr Sidecar Injector automatically creates a secret reference and injects the actual value into `APP_API_TOKEN` environment variable.
|
||||
|
||||
## Rotate a token
|
||||
|
||||
### Self-hosted
|
||||
|
||||
To rotate the configured token in self-hosted, simply set the `APP_API_TOKEN` environment variable to the new value and restart the `daprd` process.
|
||||
|
||||
### Kubernetes
|
||||
|
||||
To rotate the configured token in Kubernates, update the previously created secret with the new token in each namespace. You can do that using `kubectl patch` command, but the easiest way to update these in each namespace is by using manifest:
|
||||
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: Secret
|
||||
metadata:
|
||||
name: app-api-token
|
||||
type: Opaque
|
||||
data:
|
||||
token: <your-new-token>
|
||||
```
|
||||
|
||||
And then apply it to each namespace:
|
||||
|
||||
```shell
|
||||
kubectl apply --file token-secret.yaml --namespace <namespace-name>
|
||||
```
|
||||
|
||||
To tell Dapr to start using the new token, trigger a rolling upgrade to each one of your deployments:
|
||||
|
||||
```shell
|
||||
kubectl rollout restart deployment/<deployment-name> --namespace <namespace-name>
|
||||
```
|
||||
|
||||
> Note, assuming your service is configured with more than one replica, the key rotation process does not result in any downtime.
|
||||
|
||||
|
||||
## Authenticating requests from Dapr
|
||||
|
||||
Once app token authentication is configured in Dapr, all requests *coming from Dapr* include the token:
|
||||
|
||||
### HTTP
|
||||
|
||||
In case of HTTP, inspect the incoming request for presence of `dapr-api-token` parameter in HTTP header:
|
||||
|
||||
```shell
|
||||
dapr-api-token: <token>
|
||||
```
|
||||
|
||||
### gRPC
|
||||
|
||||
When using gRPC protocol, inspect the incoming calls for the API token on the gRPC metadata:
|
||||
|
||||
```shell
|
||||
dapr-api-token[0].
|
||||
```
|
||||
|
||||
## Accessing the token from the app
|
||||
|
||||
### Kubernetes
|
||||
|
||||
In Kubernetes, it's recommended to mount the secret to your pod as an environment variable.
|
||||
Assuming we created a secret with the name `app-api-token` to hold the token:
|
||||
|
||||
```
|
||||
containers:
|
||||
- name: mycontainer
|
||||
image: myregistry/myapp
|
||||
envFrom:
|
||||
- secretRef:
|
||||
name: app-api-token
|
||||
```
|
||||
|
||||
### Self-hosted
|
||||
|
||||
In self-hosted mode, you can set the token as an environment variable for your app:
|
||||
|
||||
```
|
||||
export APP_API_TOKEN=<my-app-token>
|
||||
```
