Docker - A Complete Hands-On Guide - Build an Image from Docker Compose and Run the Container at the Same Time

The video tutorial covers the process of creating an image and running a container using Docker Compose. It begins with an introduction to Docker Compose, followed by setting up an Apache web server. The tutorial then explains how to build and run containers, manage Docker images and containers, and concludes with best practices for naming and tagging Docker images.

What is the primary purpose of Docker Compose?

• To manage network configurations

• To create virtual machines

• To build and run containers

• To automate software testing

Which server is being set up in the Dockerfile?

• Tomcat

• Nginx

• Apache

• IIS

What is the purpose of the entry point in a Dockerfile?

• To specify the base image

• To define the command to run

• To set environment variables

• To expose ports

In Docker Compose, what does the 'build' context specify?

• The network settings

• The location of the Dockerfile

• The container's entry point

• The volume mounts

Which port is exposed in the Docker Compose configuration?

• 443

• 8080

• 80

• 85

What command is used to remove all containers and images before building?

• docker rm -f

• docker-compose down

• docker system prune

• docker rmi -f

What is the benefit of specifying image names in the Docker Compose file?

• It reduces build time

• It increases security

• It automates deployment

• It helps in organizing and managing images

What is a best practice when managing image names and tags?

• Avoid using tags

• Specify them in the Docker Compose file

• Keep them in the Dockerfile

• Use random names

How can you change the image name in Docker Compose?

• By renaming the container

• By using the 'image' field in the Compose file

• By editing the Dockerfile

• By using a different base image

What is the significance of tagging an image?

• It increases the image size

• It helps in version control

• It speeds up the build process

• It changes the base image
