When creating a secure container image, it is essential to follow best practices to minimize vulnerabilities and ensure the container operates as intended. Here are the two key practices:

Package a Single App as a Container: By packaging only a single application within a container, you reduce complexity and potential attack surfaces. This practice aligns with the principle of single responsibility, ensuring each container has a clear and focused purpose.

Remove Any Unnecessary Tools: Any additional tools or software that are not required by the application should be removed from the container image. This minimizes the number of potential vulnerabilities and reduces the attack surface. A minimal container image also leads to smaller image sizes and faster deployment times.

These practices contribute to creating a more secure and efficient container image.
