Docker Certified Associate Certification Training Course - Dockerfile Build

The video tutorial explains the process of creating Docker images from Docker files. It covers the use of the Docker build command, including its syntax and options, such as specifying paths or URLs. The tutorial also discusses the importance of the Docker ignore file in improving build efficiency by excluding unnecessary files. Additionally, it explains the concept of build context, which involves a set of files located in a specified path or URL, and how it interacts with the Docker daemon during the build process.

What is the primary command used to create a Docker image from a Docker file?

• Docker push

• Docker commit

• Docker run

• Docker build

Where can Docker images be stored after creation?

• Only on local machines

• In public or private registries

• On external hard drives

• In cloud storage

What does the Docker build command do if no path or URL is specified?

• It prompts the user to specify a path

• It downloads a default Docker file from the internet

• It looks for a Docker file in the present directory

• It searches for a Docker file in the home directory

How can you exclude certain files or directories from the Docker build process?

• By renaming them

• By listing them in a Docker ignore file

• By deleting them before building

• By using a Docker exclude file

What is the role of the build context in the Docker build process?

• It determines the runtime environment for the image

• It specifies the set of files available during the build

• It sets the default registry for image storage

• It defines the network settings for the container
