configuration

Before you run the example make sure local redis state store is running by executing:

docker ps

1. To run the example we need to first build the examples using the following command:

cargo build --examples

2. Insert a key with the value hello to redis using the following command:

docker exec dapr_redis redis-cli MSET hello "world"

3. Run the example with dapr using the following command:

dapr run --app-id=rustapp --resources-path ../components --dapr-grpc-port 50001 -- cargo run --example configuration

4. Change the value of the key hello in redis using the following command:

docker exec dapr_redis redis-cli MSET hello "world2"

If everything went well you should see the following output along with dapr logs:

Configuration value: ConfigurationItem { value: "world", version: "", metadata: {} }
