Dockerfile best-practices for writing production-worthy Docker images.

Dockerfile linter, validate inline bash, written in Haskell

Super simple build framework with fast, repeatable builds and an instantly familiar syntax – like Dockerfile and Makefile had a baby.

CI/CD pipeline configuration using GitHub Actions for Golang projects — testing, linting, SAST, security scanning, code coverage, Dependabot, Renovate, GoReleaser, code review automation, and release pipelines. Use when setting up or improving Go project CI, configuring GitHub Actions workflows, adding linters or security scanners, automating dependency updates, or adding quality gates.

Official Dockerfile for Apache Spark

Where things live in the portal-tunnel repo (sdk/portal/types/utils/cmd/discovery/x402/frontend/extensions) and where new code belongs. Use when locating functionality or deciding where to add code.

Build, lint, test, and verification workflow for the portal-tunnel Go+frontend monorepo. Use when setting up the repo, running CI-equivalent checks, or before committing changes.

Full environment-variable / flag reference for configuring the portal-tunnel relay-server (cmd/relay-server), plus how config is embedded and how Docker/Compose deploys it. Use when configuring, deploying, or debugging a relay.

Kubernetes Security Checklist and Requirements - All in One (authentication, authorization, logging, secrets, configuration, network, workloads, dockerfile)

Static security checker for Dockerfiles

Guide the user through containerizing and serving a simple website or documentation folder with Docker — inspects the project to detect what to serve (ready-to-serve static HTML, a buildable site that emits static output, or a raw markdown/docs folder that needs rendering), generates a Dockerfile, .dockerignore, docker-compose.yml, helper run/build commands, and a 'Running with Docker' README section, then offers to build and smoke-test the container and publish the image to Docker Hub or GHCR. Uses nginx:alpine for static content and a multi-stage build when the site must be generated. Only invoke when the user explicitly types /ai-assist-dockerize-website. Never auto-trigger from general conversation about Docker, containers, websites, or Dockerfiles.

GPU-ready Dockerfile to run Stability.AI stable-diffusion model v2 with a simple web interface. Includes multi-GPUs support.
