Docker Certified Associate Certification Training Course - Container Security

The video tutorial discusses the importance of scanning container images for vulnerabilities before deploying them in production environments. It introduces the Docker Trusted Registry (DTR) as a tool for scanning images, highlighting its features and configuration requirements. The tutorial explains how to set up DTR for automatic scanning and describes the two scanning methods available: online and offline. It also covers how to interpret scan results, including identifying critical and major vulnerabilities and understanding their impact on image layers.

Why is it crucial to scan containers before deploying them in a production environment?

• To improve the user interface of the application

• To ensure the application runs faster

• To prevent potential breaches due to vulnerabilities

• To reduce the size of the container

What is the primary tool discussed for scanning Docker images from a certification perspective?

• Docker Hub

• Docker Trusted Registry

• Kubernetes

• AWS ECR

What is the recommended way to scan images using Docker Trusted Registry?

• Manually scan each image

• Use a third-party scanning tool

• Enable automatic scanning when images are pushed

• Scan images only after deployment

What are the two methods available in DTR for scanning images?

• Basic and Advanced

• Local and Remote

• Offline and Online

• Manual and Automatic

How can you view detailed information about vulnerabilities found in a Docker image?

• By checking the image size

• By clicking on 'view details' in the DTR UI

• By running a command in the terminal

• By contacting Docker support
