Some of the common use cases of Docker are as follows:

1. Setting up Development Environment: We can use

Docker to set the development environment with the

applications on which our code is dependent.

2. Testing Automation Setup: Docker can also help in

creating the Testing Automation setup. We can setup

different services and apps with Docker to create the

automation testing environment.

3. Production Deployment: Docker also helps in

implementing the Production deployment for an

application. We can use it to create the exact environment

and process that will be used for doing the production

deployment.
