Quickstart: Secrets Management

Get started with Dapr’s Secrets Management building block

Dapr provides a dedicated secrets API that allows developers to retrieve secrets from a secrets store. In this quickstart, you:

1. Run a microservice with a secret store component.
2. Retrieve secrets using the Dapr secrets API in the application code.

Select your preferred language-specific Dapr SDK before proceeding with the Quickstart.

• Python
• JavaScript
• .NET
• Java
• Go

Pre-requisites

For this example, you will need:

• Dapr CLI and initialized environment.

• Python 3.7+ installed.

• Docker Desktop

Step 1: Set up the environment

Clone the sample provided in the Quickstarts repo.

git clone https://github.com/dapr/quickstarts.git

Step 2: Retrieve the secret

In a terminal window, navigate to the order-processor directory.

cd secrets_management/python/sdk/order-processor

Install the dependencies:

pip3 install -r requirements.txt

Run the order-processor service alongside a Dapr sidecar.

dapr run --app-id order-processor --resources-path ../../../components/ -- python3 app.py

Note: Since Python3.exe is not defined in Windows, you may need to use python app.py instead of python3 app.py.

Behind the scenes

order-processor service

Notice how the order-processor service below points to:

• The DAPR_SECRET_STORE defined in the local-secret-store.yaml component.
• The secret defined in secrets.json.

# app.py
DAPR_SECRET_STORE = 'localsecretstore'
SECRET_NAME = 'secret'
with DaprClient() as client:
    secret = client.get_secret(store_name=DAPR_SECRET_STORE, key=SECRET_NAME)
    logging.info('Fetched Secret: %s', secret.secret)

local-secret-store.yaml component

DAPR_SECRET_STORE is defined in the local-secret-store.yaml component file, located in secrets_management/components:

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: localsecretstore
  namespace: default
spec:
  type: secretstores.local.file
  version: v1
  metadata:
  - name: secretsFile
    value: secrets.json
  - name: nestedSeparator
    value: ":"

In the YAML file:

• metadata/name is how your application references the component (called DAPR_SECRET_STORE in the code sample).
• spec/metadata defines the connection to the secret used by the component.

secrets.json file

SECRET_NAME is defined in the secrets.json file, located in secrets_management/python/sdk/order-processor:

{
    "secret": "YourPasskeyHere"
}

Step 3: View the order-processor outputs

As specified in the application code above, the order-processor service retrieves the secret via the Dapr secret store and displays it in the console.

Order-processor output:

== APP == INFO:root:Fetched Secret: {'secret': 'YourPasskeyHere'}

Pre-requisites

For this example, you will need:

• Dapr CLI and initialized environment.
