Azure Deployment Config Drift

azure-deployment-config-drift

Production on Azure fails to load runtime dependencies and configuration (env vars, startup command, secrets, routes), so builds may pass while requests hit 404/500 or missing modules, breaking FastAPI/Gunicorn boot and API behavior.

MATCHESSolution

I just switched from npm to pnpm — Azure App Service. Tension: app services tries to run npm install.

MATCHESSolution

webpack config. Tension: These two solutions can both fix this issue.

MATCHESSolution

Configure AWS Amplify to use the correct monorepo root/workspace (e.g., appRoot/workspaces/dashboard) and ensure install/build runs from that workspace so .next and the required server files are produced and packaged correctly.

MATCHESSolution

I couldn't find any clear solution — from this template. Tension: the issue persists. Outcome: I am deploying backend and frontend separately.

MATCHESSolution

Move parts of your code to Azure — code that talks to Azure resources in Azure. Tension: then expose that functionality through some API. Outcome: that you will consume through your NextJS app code running in Vercel.

MATCHESSolution

Host your NextJS app in Azure Static WebApp — hosting NextJS app there. Tension: the developer experience of hosting NextJS app there is extremely poor. Outcome: the last time I tried, it just did not work.

MATCHESSolution

override Build command to `npx prisma generate && next build` — under Build & Development Settings. Tension: API route failed. Outcome: Redeploy the app.

MATCHESSolution

Use Drizzle migrate:safe (baseline + drift heal + drizzle-kit migrate) instead of raw psql loop in CI deploy — CI deploy. Tension: instead of raw psql loop. Outcome: baseline + drift heal + drizzle-kit migrate.

MATCHESSolution

If you convert all operations to perform asynchronously (using `aiosqlite`) , the issue will be mitigated. — When a route in FastAPI is listed as asynchronous (`async def`). Tension: that doesn't fully solve the inherent single writer problem of Sqlite. Outcome: Here's a fully operational update of the FastAPI server logic:.

MATCHESSolution

You can use a global dependency: — FastAPI. Tension: there's no way to set auth tokens in the docs. Outcome: app.openapi = custom_openapi.

MATCHESSolution

Azure App Service. Outcome: and then it worked.

MATCHESSolution

I tried adding a `startup.sh` file with this command: `gunicorn -w 4 -k uvicorn.workers.UvicornWorker main:app`, without any luck. — Azure App Service. Tension: without any luck.

MATCHESSolution

launched the web app with the built-in fastapi command — Now my dockerfile looks like this. Tension: problem seems to be gone. Outcome: CMD ["fastapi", "run", "main", "--port", "8121", "--workers", "3"].

MATCHESSolution

Try `fastapi run` instead of `fastapi dev` — if you use --reload or reload=True.

MATCHESSolution

This mismatch necessitates a manual conversion of the OpenAPI document to version 2.0 — before it can be utilized by API Gateway. Tension: Incompatibility issue between the OpenAPI document supported by GCP API Gateway, and the OpenAPI document automatically generated from FastAPI itself. Outcome: The Solution: For this will be clearly explained in the Link.

MATCHESSolution

Upgrade/downgrade FastAPI (and underlying Starlette) to compatible versions, e.g., reinstall with a specific FastAPI version such as fastapi==0.115.6 after uninstalling fastapi/starlette/pydantic.

MATCHESSolution

I have enabled CORS. — deployed to Azure web app. Tension: we can't see it being recieved on the frontend. Outcome: Upgrade your app service plan which can handle computation.

MATCHESSolution

Update the frontend to call the API over HTTPS (https://my-api.azurewebsites.net/v1/user/{user_id}). Additionally, configure the Azure Web App to redirect HTTP traffic to HTTPS so insecure requests are automatically upgraded.

MATCHESSolution

Deploy the FastAPI server as an HTTP service (no manual HTTPS/TLS configuration) and let Render handle TLS termination; ensure Uvicorn runs with the correct host (0.0.0.0) and the PORT environment variable.

MATCHESSolution

Also increase the timeout value for the client. — Deploy the application to Azure again through a different way (VSCode or Azure CLI). Tension: check the logs of the Azure App Service for the complete error details. Outcome: Deploy the application to Azure again through a different way (VSCode or Azure CLI) and check the logs of the Azure App Service for the complete error details.

MATCHESSolution

the deployment fails silently when my code includes azure-identity — deploy a Python Azure Function using GitHub Actions. Tension: The function works perfectly when deployed through VS Code, but not through GitHub Actions. Outcome: replacing the `Azure/functions-action@v1` task with a pwsh task below.

MATCHESSolution

splitting the 12 apps that are on the original ASP and moving half under the new ASP — We are running 12 rather small Azure Function on the Flexible Premium Function service plan. Tension: I do not see us purchasing an additional ASP only to fix this issue. Outcome: we will be implementing our own health-check routine instead.

MATCHESSolution

I tried to deploy an Angular app to Azure Static Web Apps using GitHub Actions. Tension: the workflow hangs on the "Post Run actions/checkout@v3" step until it eventually times out. Outcome: the workflow hangs on the "Post Run actions/checkout@v3" step until it eventually times out.

MATCHESSolution

Set the settings manually in Azure App Service, or use a deployment action to set them via API

MATCHESSolution

Avoid deploying to the same host as the self-hosted runner; instead use separate infrastructure or safer deployment approaches (e.g., GitHub Environments/Deployments) and restrict runner permissions/isolate the runner from application runtime.

MATCHESSolution

Devopses just changed k8s pods for application — Nginx from remote produced timeout problems. Tension: nginx stopped closing the connection my app to remote. Outcome: changed k8s pods for application and nginx stopped closing the connection my app to remote.

MATCHESSolution

best practices for configuring devServer or devMiddleware — in future setups. Tension: prevent such vulnerabilities. Outcome: without upgrading the entire Vue CLI or webpack stack.

MATCHESSolution

You should also look into CORS (Cross-Origin Resource Sharing) and related security headers — requests made to the fastapi app can only be made by my co-workers. Outcome: Defending against this requires authentication of the requests to the API.

MATCHESSolution

needs to have distinct configurations for different environments, including development, staging, and production — I'm developing a Laravel application. Tension: These configurations involve various settings such as database connections, cache drivers, and API keys. Outcome: Laravel will attempt to load an .env.[APP_ENV] file if it exists.

MATCHESSolution

Current workaround is to change your app service to use http 1.1. — Azure app service monitoring tools are limited. Tension: The App Service product team are currently investigating the problem. Outcome: Current workaround is to change your app service to use http 1.1.
