Take actions to improve security in your Docker images, the top two most popular Docker base images each have over 500 vulnerabilities. Choosing the right base image is crucial as it can make a significant difference in reducing the attack surface of an image. Using tools like Buildah and Alpine Linux can help trim down the number of vulnerabilities by creating minimal production images with only the packages required to run your application. Multi-stage builds are also recommended, which allow you to selectively copy artifacts from one image to another, reducing complexity and the risk of implementing vulnerable artifacts. Rebuilding images regularly is essential, especially after a vulnerability has been patched, and using automated scanning tools like Snyk can help identify vulnerabilities before they reach production. Scanning Docker images during development and production is also crucial to catch vulnerabilities early on and prevent them from reaching production environments.
