1. Start With a Minimal Base Image
Starting with a basic, minimum image is essential when creating Docker images. This method minimizes security concerns while shrinking the image size. For basic base images, Alpine Linux and scratch (an empty base image) are common options. Avoid utilizing heavyweight base pictures unless essential and select a base image that complies with the needs of your application.
There are various benefits to starting with a simple basic image. As fewer packages and libraries are included, it first decreases the attack surface of your container. As a result, security flaws are less likely to occur. Second, reduced image sizes result, making it simpler to share and deploy your container.
