The command "snyk test --docker ${docker_image}" is used to scan a Docker image for potential security vulnerabilities using Snyk.

Here's a breakdown of the command:

• "snyk test" is the command to initiate a security scan using Snyk.
• "--docker" specifies that the scan will be performed on a Docker image.
• "${docker_image}" represents the variable that holds the name or ID of the Docker image to be scanned. This variable should be substituted with the actual image name or ID before executing the command.

When you run this command, Snyk will analyze the specified Docker image, examining the Dockerfile, installed packages, and their versions to identify any known vulnerabilities. The result will be a report that indicates any security issues found within the image.
