Introduction:

Microservices architecture offers flexibility and scalability, but as demand grows, scaling becomes a crucial consideration.

We’ll discuss how to modify the Docker networking setup to deploy multiple instances of the catalog service efficiently.

Establishing the Initial Docker Networking Setup:

To set the stage, let’s recap our initial Docker networking setup. We created a custom Docker network named “my_network” to facilitate communication between microservices, particularly the authentication and product catalog services.

docker network create my_network
docker run --name…
