Docker Dockerfile and Docker Compose 2020 Ready - This is how you use Docker-Compose to Start and Stop Services

The video tutorial explains how to use Docker Compose for volume mounting, allowing instant updates without rebuilding images. It covers using base images like PHP 7.2 Apache, running containers with Docker Compose, and creating reproducible development environments. The tutorial concludes with a cleanup process and a preview of building custom images in the next lecture.

What is the main advantage of using a Docker Compose file with volume mounting?

• It reduces the size of the Docker image.

• It increases the security of the application.

• It eliminates the need to build a new image for every change.

• It allows for faster image builds.

• Changes require a manual refresh of the browser.

• Changes are not reflected until a new image is built.

• Changes are reflected immediately without restarting.

• Changes are reflected after restarting the container.

What is a benefit of using pre-built images from repositories like Docker Hub?

• They allow for faster application execution.

• They provide a consistent development environment.

• They reduce the need for volume mounting.

• They automatically update the application code.

Why is volume mounting important in Docker Compose?

• It simplifies the Docker Compose file syntax.
