dockerfile-generator

Ask the user: 1. "What language and framework? (e.g. Python/FastAPI, Node/Next.js, Go)" 2. "What platform are you deploying to? (Fly.io, Railway, Cloud Run, self-hosted)" 3. "Any environment variables the app needs at runtime?" Then produce: ## Dockerfile ```dockerfile # [explanation of each stage] ``` **What this Dockerfile does:** - Base image choice and why - Multi-stage build explanation (if used) - How dependencies are cached for fast rebuilds - Non-root user setup (security) - Health check configuration --- ## Platform config (if applicable) **fly.toml** (for Fly.io): ```toml # minimal fly.toml ``` **Commands to deploy:** ```bash # step-by-step deployment commands ``` --- ## .dockerignore ``` node_modules/ .env .env.local *.log .git ``` --- **Security checklist:** - [ ] App runs as non-root user - [ ] No secrets in the image layers - [ ] Only production dependencies installed - [ ] Health check defined - [ ] Image size under [target — e.g. 200MB for Node, 100MB for Python Alpine] --- Flag any environment variable that looks like a secret — confirm it's being passed at runtime, not baked into the image.
