Docker is a platform for developing, shipping, and running applications in containers. Containers are lightweight, isolated environments that package an application and its dependencies, ensuring consistency across different environments.

In full-stack development, Docker is used to simplify deployment and scaling. For example, a Docker container can include a Django backend, a React frontend, and a PostgreSQL database, all configured to work together. This makes it easy to deploy the application to any environment that supports Docker.

Docker also improves collaboration by ensuring that all developers use the same environment. By using a Dockerfile and docker-compose.yml, teams can quickly set up and share development environments, reducing the risk of configuration issues.
