Run containers with a defensive baseline that survives production. Covers non-root users, read-only filesystems, dropped Linux capabilities, secret mounts instead of build-time bake-in, image scanning with trivy, distroless and minimal base images, and the Docker-bypasses-UFW firewall pitfall. Invoke when adding Docker to a VPS with UFW, writing a new Dockerfile, or pushing an image to a public registry.

From the source SKILL.md

A pragmatic baseline for Docker on a single VPS or a small cluster. Covers the Dockerfile, the run-time configuration, and the host-side gotchas — particularly the UFW-bypass that catches most people once.

What this skill does

docker-container-security is a community-contributed Claude Code skill in the cloud-security sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/gw360--docker-container-security/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The docker-container-security Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 146,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
