How To: Retrieve a secret

Use the secret store building block to securely retrieve a secret

Now that you’ve learned what the Dapr secrets building block provides, learn how it can work in your service. This guide demonstrates how to call the secrets API and retrieve secrets in your application code from a configured secret store.

Set up a secret store

Before retrieving secrets in your application’s code, you must configure a secret store component. This example configures a secret store that uses a local JSON file to store secrets.

In your project directory, create a file named secrets.json with the following contents:

{
   "secret": "Order Processing pass key"
}

Create a new directory named components. Navigate into that directory and create a component file named local-secret-store.yaml with the following contents:

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

Get a secret

Get the secret by calling the Dapr sidecar using the secrets API:

curl http://localhost:3601/v1.0/secrets/localsecretstore/secret

See a full API reference.

Calling the secrets API from your code

Now that you’ve set up the local secret store, call Dapr to get the secrets from your application code. Below are code examples that leverage Dapr SDKs for retrieving a secret.

using System;
using System.Threading.Tasks;
using Dapr.Client;

namespace EventService;

const string SECRET_STORE_NAME = "localsecretstore";

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddDaprClient();
var app = builder.Build();

//Resolve a DaprClient from DI
var daprClient = app.Services.GetRequiredService<DaprClient>();

//Use the Dapr SDK to get a secret
var secret = await daprClient.GetSecretAsync(SECRET_STORE_NAME, "secret");

Console.WriteLine($"Result: {string.Join(", ", secret)}");

        //Using Dapr SDK to get a secret
