docker-container-expert

docker-container-expert is a skill for Cursor from roedyrustam/vibes-plug. It costs 68 tokens per session (2,820 once invoked), scanned A, original, MIT.

A guide to packaging applications as Docker containers and running them with Docker Compose. Docker containers bundle an application with its runtime, while Compose describes how multiple containers work together.

In plain words
What is it for?
Use it to write Dockerfiles, build multi-stage images, add build caching and health checks, harden containers, create isolated networks, and build images for multiple processor types.
Why use it?
It helps create smaller, repeatable images and reduce common security risks such as running as root or exposing unnecessary system capabilities. It also helps coordinate local and production services reliably.

Skill for Cursor

Written for Cursor: shipped in a Cursor plugin.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is go build -ldflags="-w -s" -o /bin/server ./cmd/server.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

docker-container-expert scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Docker Container Expert (Production Standard 2026)

English | Bahasa Indonesia

Orchestration & Integration

  • Upstream & Lifecycle: zero-to-prod-orchestrator (Phase 7 containerization), brainstorming, session-memory-manager.
  • CI/CD & Cloud Runtime: ci-cd-devops-architect (K8s & deployment pipelines), github-actions-expert (BuildKit actions & registry push), cloud-hosting-expert (container runtime hosts).
  • Backend & Database Runtimes: js-backend-expert (Node/Bun/Deno), python-programming-expert, go-programming-expert, rust-programming-expert, database-orm-expert (Postgres/Redis services).
  • Security & Hardening: production-ready-hardener (distroless & nonroot audit), zero-trust-secret-vault (build secret mounts).

Description

Enterprise guide for building ultra-lean, hardened, and reproducible container images and orchestrating local and production workloads with Docker Engine 27+ and Docker Compose v2. Covers BuildKit cache mounts (--mount=type=cache), secret mounts (--mount=type=secret), multi-stage builds targeting Google Distroless or Alpine Linux, non-root execution (UID 65532), dropping Linux kernel capabilities (cap_drop: ALL), health checks (HEALTHCHECK), internal isolated bridge networks, compose dependency sequencing (condition: service_healthy), and multi-architecture builds via docker buildx.

Trigger Conditions

  • Writing, refactoring, or optimizing Dockerfile manifests for Node.js, Python, Go, Rust, or Bun.
  • Structuring multi-container local and staging topologies with compose.yaml.
  • Accelerating build speeds using Docker BuildKit cache mounts and layer ordering.
  • Minimizing image attack surface: eliminating shell binaries, package managers, and root permissions.
  • Hardening container security: dropping Linux capabilities, setting read-only filesystems, and enforcing memory/CPU limits.
  • Configuring robust health checks and zero-downtime container lifecycle management.
