Redis

To setup Redis configuration store create a component of type . See this guide on how to create and apply a configuration store configuration.

Warning

The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described here.

Dapr can use any Redis instance: containerized, running on your local dev machine, or a managed cloud service.

A Redis instance is automatically created as a Docker container when you run dapr init

You can use to quickly create a Redis instance in our Kubernetes cluster. This approach requires Installing Helm.

  1. Install Redis into your cluster. Note that we’re explicitly setting an image tag to get a version greater than 5, which is what Dapr’ pub/sub functionality requires. If you’re intending on using Redis as just a state store (and not for pub/sub), you do not have to set the image version.

  2. Run kubectl get pods to see the Redis containers now running in your cluster.

  4. Next, get the Redis password, which is slightly different depending on the OS we’re using:

    • Windows: Run kubectl get secret --namespace default redis -o jsonpath="{.data.redis-password}" > encoded.b64, which creates a file with your encoded password. Next, run certutil -decode encoded.b64 password.txt, which will put your redis password in a text file called password.txt. Copy the password and delete the two files.

    • Linux/MacOS: Run kubectl get secret --namespace default redis -o jsonpath="{.data.redis-password}" | base64 --decode and copy the outputted password.

    Add this password as the redisPassword value in your file. For example:

Note: this approach requires having an Azure Subscription.

  1. Start the Azure Cache for Redis creation flow. Log in if necessary.

  3. Once your instance is created, you’ll need to grab the Host name (FQDN) and your access key:

    • For the Host name: navigate to the resource’s “Overview” and copy “Host name”.
    • For your access key: navigate to “Settings” > “Access Keys” to copy and save your key.

  4. Add your key and your host to a redis.yaml file that Dapr can apply to your cluster.

    • If you’re running a sample, add the host and key to the provided redis.yaml.
    • If you’re creating a project from the ground up, create a redis.yaml file as specified in .

    Set the redisHost key to and the redisPassword key to the key you saved earlier.

    Note: In a production-grade application, follow secret management instructions to securely manage your secrets.
