Helps with Docker, security as part of deploying and managing cloud infrastructure workflows.

Repository

Install on your platform

Showing Claude Code. One command installs this skill into any of the agents below.

  1. 1

    Run this in your project

    terminal
    $ npx skills add josiahsiegel/claude-plugin-marketplace --skill docker-security-guide -a claude-code

  2. Uses the open-source skills CLI and needs Node.js. Add -g to install it for your user instead of this project.

Install target

Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 2 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No credential access: failed

    Touches credential material in 1 place.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

    What it found

    • plugins/docker-master/skills/docker-security-guide/references/build-runtime-security.md:271SSH private keys or config
      id_rsa

  • No pipe-to-shell installers: failed

    Runs code fetched at install time in 1 place.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

    What it found

    • plugins/docker-master/skills/docker-security-guide/references/build-runtime-security.md:138remote script piped into a shell
      curl -sSfL https://raw.githubusercontent.com/anchore/syft/main/install.sh | sh

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Only contacts known or declared hosts: raw.githubusercontent.com.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

    Hosts contacted

    raw.githubusercontent.comsource host

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • Pinned to a commit: passed

    Scanned josiahsiegel/claude-plugin-marketplace at 5a1b1123b9.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill empowers AI agents to generate comprehensive security best practices and audit checklists specifically tailored for Docker containerization. It helps teams identify potential vulnerabilities in their container configurations and deployment strategies before they reach production environments.

When to use it

  • Pre-deployment Audits: Before launching a new microservice, run the agent to validate Dockerfile instructions and security flags.
  • Compliance Checks: Ensure container setups meet industry standards like CIS Docker Benchmark or SOC2 requirements.
  • Incident Response: Quickly generate remediation steps for identified container vulnerabilities during a security review.
  • Team Training: Create educational materials explaining secure coding practices for developers new to container orchestration.

Key capabilities

  • Generates actionable security recommendations based on current Docker engine standards.
  • Provides structured checklists for reviewing docker-compose.yml and multi-stage builds.
  • Highlights common misconfigurations such as running containers as root or exposing unnecessary ports.
  • Offers context-aware advice aligned with cloud-native security principles.

Example prompts

  • "Generate a security checklist for my production Docker deployment including network isolation and image scanning."
  • "Review these Dockerfile instructions and suggest hardening steps to prevent privilege escalation."
  • "Explain the risks of using --privileged mode in Kubernetes pods and provide safer alternatives."

Tips & gotchas

Ensure your AI agent has access to your specific infrastructure details (e.g., cloud provider constraints) for the most relevant advice. While this guide offers best practices, it should be combined with automated scanning tools like Trivy or Clair for real-time vulnerability detection.
