What are the common use cases of Docker?

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

1. Setting up Development Environment: We can use Docker to set up the development environment with the
   applications on which our code is dependent.
2. Testing Automation Setup: Docker can also help in creating the TestingAutomation setup. We can set up 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 the production deployment.
