Docker image hardening services for smaller, safer containers

Docker image hardening services strip your containers down to what they need to run. Omeiro moves images to minimal distroless bases, removes package managers, runs processes as a non-root user and signs images with Sigstore Cosign.

Smaller images carry fewer vulnerabilities to patch.

Docker image hardening scope: what to prepare and what to expect

Docker image hardening scope depends on the variety of your images, not just the count. Ten images built from one shared base are quicker to harden than three with different languages and native libraries. Prepare your Dockerfiles, the registry you push to, and notes on anything the app needs at runtime, such as shell scripts, certificates or writable folders. Those details decide whether a distroless base works as is or needs a multi-stage build that copies in only what the app requires.

A classic mistake is stripping an image so far that nobody can debug it, or running as non-root while the app still writes to root-owned paths. We test each rebuilt image by starting the container, calling health endpoints and checking file permissions before handover. A good result is a smaller image, fewer packages for scanners to flag, a non-root user and a short note on how your team can troubleshoot it when something breaks.
