container-security-hardening
Harden Docker/container images and runtime deployments with secure base images, non-root users, CVE scanning, SBOM/signing, seccomp/AppArmor, and Kubernetes pod security controls. Use for Dockerfile security reviews, container CVEs, image scanning, distroless images, or production hardening.

Container Security Hardening Skill
A production-focused guide for building, scanning, and running containers securely — from Dockerfile authoring through runtime enforcement and supply chain integrity.
Detailed Guide
Read [the detailed guide](references/detailed-guide.md) before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.
When to Use This Skill
- User mentions Docker security, container hardening, or Dockerfile security review
- User asks about distroless images, non-root containers, or read-only filesystems
- User wants to scan images for CVEs with Trivy, Grype, or Snyk
- User mentions seccomp, AppArmor, Linux capabilities, or runtime security
- User asks "is my Dockerfile secure?" or "how do I reduce my image attack surface?"
- User wants to sign/verify images with Cosign or generate SBOMs
- User asks about Kubernetes pod security, NetworkPolicy, or RBAC hardening
- User says "fix container CVEs" or "harden my container for production"
When NOT to Use This Skill
- The user is primarily asking about GitHub Actions CI/CD → recommend
github-actions-advanced - The user needs general Docker usage help (not security) → recommend
