The repo has a base which needs to be started before starting anything else. The base serves as the entry point into the mesh.
cd base
npm install
node index.js
Next bring up the service1. From the parent directory:
cd service1
npm install
node index.js
You can bring up another instance of the same service by running again
node index.js
Now bring up the client. From the parent directory
cd service2
npm install
node index.js
If you run the below curl command you will see the request being executed in a round robin manner between the 2 instances of the service1 that you have started.
curl http://localhost:10081/api/retrieve/123
