In this quickstart, you'll create a microservice which makes use of Dapr's Configuration API. Configuration items are key/value pairs containing configuration data such as app ids, partition keys, database names etc. The service gets configuration items from the configuration store and subscribes for configuration updates.
Visit this link for more information about Dapr and Configuration API.
This quickstart includes one service:
- Node service
order-processor
- Locally running redis container - a redis container named
dapr_redis
is automatically created when you rundapr init
- Open a new terminal and set values for config items
orderId1
andorderId2
by using the command below
docker exec dapr_redis redis-cli MSET orderId1 "101" orderId2 "102"
- Navigate to folder and install dependencies:
cd ./order-processor
npm install
- Run the Node app with Dapr:
cd ./order-processor
dapr run --app-id order-processor --resources-path ../../../components/ --app-protocol grpc --dapr-grpc-port 3500 -- node index.js
- Keep the
order-processor
app running and open a separate terminal - Change the values of
orderId1
andorderId2
using the command below order-processor
app gets the updated values of config items
docker exec dapr_redis redis-cli MSET orderId1 "103" orderId2 "104"
