Use the below-mentioned steps to link containers in a docker-compose file:-

  • Firstly, create a custom Docker network named consumer-producer network.

  • After that start container named producer using image employee-producer and the custom network consumer-producer.

  • Lastly, start a container named consumer using image employee-consumer and the custom network consumer-producer.

All the above steps can be automated using docker-compose. The compose file will be as follows:- 

version: "3"

services:

 consumer:

   image: employee-consumer

   networks:

     - consumer-producer

   depends_on:

     - producer

 producer:

   image: employee-producer

   ports:

     - "8080:8080"

   networks:

     - consumer-producer

networks:

 consumer-producer:
