Docker Compose Exercise 3 - Connecting Containers!

Introduction:

Welcome to the Docker Compose Exercise 3 - Connecting Containers! This exercise focuses on connecting containers created through Docker Compose to enable communication between applications.

Background:

A forward-thinking technology company is in the process of containerizing their application stack. They aim to streamline the local setup of services using Docker Compose.

They have developed two applications:

• The first application allows users to input their username and a movie name of their choice, which is then stored in a Redis database.
• The second application retrieves the movie associated with a given username from the Redis database.

Requirements:

Your task is to configure Docker Compose files to meet the following requirements:

• Do not Modify App1 Directory Files: Ensure that no modifications are made to the files within the app1/ directory.
• Connect App2 to Redis DB: App2 should be able to connect to the Redis database created as part of App1.

Expected outcome

1. 1. App1 Sending Data to Redis DB:

App1 should successfully send data to the Redis database.

2. App2 Retrieving Movie Associated with User:

App2 should be able to return the movie associated with the user entered in App1.

3. App2 Returning "User Not Found" Response:

App2 should return a "user not found" response when a nonexistent user value is provided.

Hint

App2 is not able to connect to Redis DB created by app1 compose config. Redis DB will be created in movie_default network which is created as part of app1 setup. You need to enable App2 to be able to connect with Redis DB in movie_default network
