lynis: Run a security audit of a Dockerfile.
$ sudo lynis audit dockerfile ${path-to-dockerfile}
try on your machine

The command you provided is used to run a security audit on a Dockerfile using the Lynis tool. Here is the breakdown of the command:

  • sudo: This is a command that allows you to run a command with administrative privileges. In this case, it is used to execute the Lynis audit command as a superuser.

  • lynis: This is the name of the tool you are using. Lynis is an open-source security auditing tool that scans systems for vulnerabilities and provides recommendations for improvement.

  • audit: This is the command you are running with Lynis. It instructs Lynis to perform a security audit on a specific target, which in this case is a Dockerfile.

  • dockerfile: This parameter is used to tell Lynis that the target to be audited is a Dockerfile. It helps Lynis to detect specific security risks related to Dockerfile usage.

  • ${path-to-dockerfile}: This is a placeholder for the actual path to the Dockerfile you want to audit. You need to replace ${path-to-dockerfile} with the actual file path on your system.

By executing this command, Lynis will perform a security audit on the specified Dockerfile, scanning it for various security issues, vulnerabilities, and best practices. The output of the audit will provide you with recommendations on how to improve the security of your Dockerfile.
