Install Python Appservice Deploy

Pick your agent. Every command is ready to paste.

$npx skills add microsoft/azure-skills --skill python-appservice-deploy

The open skills CLI detects your agents (Claude Code, Cursor, Codex and 70+ more) and installs to the right folder. Add -g to install globally.

01

Install it

Run the command above, or upload the folder in Claude.

02

Ask naturally

Describe the task. Your agent loads python-appservice-deploy when the request matches its description.

03

Name it if needed

If it does not trigger, say “use the python-appservice-deploy skill”. In Codex, type $python-appservice-deploy.

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

Prerequisite: Verify the latest stable Azure CLI; update with approval and recheck if needed.

  1. 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.
  2. Detect framework (advisory, never blocks). detect.md.
  3. Choose path — azure.yaml host: appservice → deploy-azd.md; else deploy-azcli.md.
  4. Ensure RG → Plan (P0v3 --is-linux) → Web App (--runtime "PYTHON:3.14") exist. Before creating a plan, invoke azure-quotas to check quota availability. On transient ARM errors, follow transient-retry.md. create-app.md.
  5. 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.
  6. Set SCM_DO_BUILD_DURING_DEPLOYMENT=true.
  7. Deploy — azd deploy or az webapp deploy --type zip --track-status false --enriched-errors true.
  8. STOP. Print the post-deploy message (post-deploy-message.md) and end the turn.

Hard rules

  • LINUX SCRIPTS — normalize selected shell/startup files to LF, then verify no CR bytes remain. Stop on normalization, validation or packaging failure; deploy only a fresh package.
  • DJANGO REMOTE BUILDS — require STATIC_ROOT and successful system/collectstatic checks before packaging.
  • ⛔ 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.

Tips for Python Appservice Deploy

  • • Start a fresh session after installing so your agent picks up the new skill.
  • • This skill ships scripts. Read them before the first run, and run it in a project without secrets first.
  • • It bundles reference files. The agent reads them only when needed, so they cost no context until then.
  • • It is part of a pack with 30 skills. Install only the ones you need with --skill to keep triggers precise.
  • • If two skills overlap, mention the one you want by name.
