Some of the common use cases of Docker are as follows:
Setting up Development Environment: We can use Docker to set up the development environment with the applications on which our code is dependent.
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.
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.
