Container Security Hardening & Vulnerability Scanning Pipeline
Added automated container vulnerability scanning and hardening to a Docker-based deployment pipeline that had no security gating before images reached production.
01
The Challenge
Docker images were being built and deployed to production without any vulnerability scanning, and several base images in use hadn't been updated in over a year, carrying known CVEs.
02
The Approach
1
Integrated Trivy into the CI pipeline to scan every image for known vulnerabilities before it can be pushed to the registry.
2
Set severity-based gating so builds with critical, unpatched vulnerabilities fail the pipeline instead of shipping.
3
Migrated base images to minimal, actively maintained distributions to shrink the attack surface.
4
Documented a base image update cadence so the fleet doesn't silently drift out of date again.
03
The Outcome
Vulnerability scanning now runs on every build, several previously unnoticed critical CVEs were closed during the initial rollout, and the pipeline now prevents known-vulnerable images from reaching production.
