Multi-Stage Docker Builds: A Security Pattern, Not Just a Size Trick
Multi-stage builds are pitched as a way to shrink images. Their bigger payoff is security: build secrets, compilers, and toolchains that never reach production. Here is how to use them right.
Docker Layer Caching Security Risks (and How to Avoid Them)
Layer caching makes builds fast — and quietly bakes secrets into layers, hides unpatched base images, and poisons shared CI caches. Here is how to keep caching without the exposure.
Docker Secrets Management: Stop Baking Credentials Into Images
A secret written into a Docker layer is recoverable forever, even after you delete it. Learn the build-time and runtime patterns that keep credentials out of your images entirely.
