Step 3: Add the following environment variable line in Dockerfile.

ENV SERVER_NAME=<Server_name>

Change the value in that variable as below.

<Server_name>= The name of the agent shown in the Applicare console.

<Applicare_IP>= The IP address of the machine running the Applicare controller.

Step 4: Comment the CMD line already in the Dockerfile. Add below CMD line.
