Is Docker commonly used in front-end or back-end development?

Docker is commonly used in back-end development. It provides consistency between where the server, database, and APIs are running from, helping in integrating or even deploying to multiple systems. Less used in front-end development, Docker can be of quite some use in preparing a development environment or serving static assets. Its strong points are dealing with complex back-end architectures, like microservices, through containerization that simplifies scaling, deployment, and maintenance. Developers use Docker to simplify their workflows by deploying applications that work the same in the local, staging, and production environments, irrespective of infrastructure.
