To configure the different microservices, there are several environment variables the user can define to customize the configurations.

A list of the most commonly used environment variables is presented below:

• ENABLE_REBUILD_INDEX_AT_INIT: Boolean flag to truncate the index and rebuild at application init.

cd lisk-service/services/blockchain-app-registry # move into the root directory of the blockcha
in-app-registry microservice
npm start # start the microservice

Use the framework/bin/moleculer_client.js and framework/bin/moleculer_subscribe.js clients to test specific service endpoints.

Once the process is verified as running correctly, press CTRL+C and start the process with P M2. This will fork the process into the background and automatically recover the process if it fails.
