python-appservice-deploy
Deploy Python (Flask/Django/FastAPI) code to Azure App Service Linux. WHEN: "Flask App Service", "Django App Service", "FastAPI App Service", "deploy Python to App Service". DO NOT USE FOR: Container Apps, Functions, non-Python, Terraform/Bicep/IaC, full infra — use azure-prepare.

- Gen Agent Trust Hubpass
This skill provides a secure and structured workflow for deploying Python applications to Azure App Service using official Microsoft CLI tools. It incorporates security best practices, such as excluding sensitive environment files from deployment packages and providing guidance on shell-safe command execution. The inclusion of idempotent resource creation scripts and automated framework detection ensures a consistent and secure deployment process.

What does this agent skill do?
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.
MCP tools used: mcp_azure_mcp_subscription_list, mcp_azure_mcp_group_list, mcp_azure_mcp_appservice, mcp_azure_mcp_azd (when azure.yaml is present).
Workflow
- Resolve context — smart defaults, minimal prompts. Only the app name is interactive; RG (
<app>-rg), Plan (<app>-plan), region (currentazdefault oreastus2), subscription are derived. create-app.md §1. - Detect framework (advisory, never blocks). detect.md.
- Choose path —
azure.yamlhost: appservice → deploy-azd.md; else deploy-azcli.md. - Ensure RG → Plan (
P0v3 --is-linux) → Web App (--runtime "PYTHON:3.14") exist. On transient ARM errors, follow transient-retry.md. create-app.md. - Set startup — Flask/Django: none (Oryx auto-detects). FastAPI: always
python -m uvicorn main:app --host 0.0.0.0. Other: warn. startup-commands.md. - Set
SCM_DO_BUILD_DURING_DEPLOYMENT=true. - Deploy —
azd deployoraz webapp deploy --type zip --track-status false. - STOP. Print the post-deploy message (post-deploy-message.md) and end the turn.
Hard rules
- ⛔ 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
--runtimealways 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.
