Python on Azure App Service — Code Deploy
Deploys Python (Flask, Django, FastAPI, generic) code to Azure App Service Linux (P0v3, Python 3.14). Creates RG + Plan + Web App if missing. Hand off to azure-prepare for VNet, Key Vault, databases, or IaC.
Resolve context — smart defaults, minimal prompts. Only the app name is interactive; RG (<app>-rg), Plan (<app>-plan), region (current az default or eastus2), subscription are derived. create-app.md §1.
Detect framework (advisory, never blocks). detect.md.
⛔ NO POST-DEPLOY VERIFICATION — after deploy returns, do not run az webapp log tail, curl, Invoke-WebRequest, or any health probe. App Service needs 2–3 min to warm; a quiet log or early 5xx is not failure.
⛔ SHELL SAFETY — for --runtime always use "PYTHON:3.14" (colon). Never "PYTHON|3.14" (pipe is a shell operator).
⛔ NEVER az webapp up — deprecated. Use Step 7 commands.
✅ URL FORMAT — present endpoints as https://... URLs.
Error Handling
See errors.md for the full symptom → cause → fix matrix. Quick triage: missing plan/app → re-run Step 4; container ping timeout on 8000 → fix startup (Step 5); ModuleNotFoundError after deploy → ensure Step 6 ran, redeploy.
