Docker Compose Stack Review skill for Claude and Codex

Docker Compose Stack Review as an AI skill. It asks for The compose file, Purpose, Services that hold data and 2 more, then does the rest. Free to install in…

Install it once and Claude or Codex runs it for you. When your request matches, your AI loads the skill, asks for anything it is missing, and works through the template itself. Prefer to fill it in by hand? See the full prompt template.

When it is used

Use when a Docker Compose file needs a check of service startup order, networks, volumes, healthchecks, and container security. Do not use for Kubernetes manifests or optimising a single Dockerfile. Related topics: devops, coding.

What it will ask you for

• The compose file (longer free text)
• Purpose (choose one: Local development, CI, Single-server production)
• Services that hold data (free text, e.g. "Postgres and Redis")
• Focus (choose any: Networks, Volumes, Healthchecks, Startup order, Secrets, Container security, Resource limits)
• Exposed to the internet (choose one: Yes, No)

How it works

1. Read every service and note its image, ports, volumes, networks, restart policy, and dependencies.
2. Check startup order uses healthchecks that test real readiness, and that restart policies suit the stated purpose.
3. Restrict published ports and put internal services on a private network, and confirm data services use named volumes.
4. Flag security risks such as privileged mode, root users, the Docker socket mount, and secrets inline in the file.
5. Return findings by severity and the corrected compose file with a comment on each change.

What you get

A short findings list by severity, then the corrected compose file with a comment on every changed line.

What it watches out for

• Using depends_on without a health condition, so the app starts before the database accepts connections.
• Publishing the database port to the host for convenience and leaving it open on a public server.
• Committing an env file with real credentials alongside the compose file.
