Uvicorn Startup Breakage

uvicorn-nginx-docker-cli-interference

Uvicorn fails to start correctly in containerized deployments because Docker volume mounts, NGINX proxy configuration, and/or application argument parsing interfere with the expected module import and CLI arguments (e.g., main:app), causing “could not import module” and broken uploads/ranges.

MATCHESSolution

The solution here looks ver y plausible but didn’t have any visible effect. — inside Tanstack Start / Vite / Vinxi. Tension: Default imports and everything else I could find did not work. Outcome: Create a `jsconfig.json` file with the following content:.

MATCHESSolution

`omnimart@0.1.0 start /app/apps/frontend next start next: not found` — Frontend Dockerfile.

MATCHESSolution

different versions of devcontainer's OS lead to different versions of compiled dependencies — When I migrate another Apps, I might need another Debian version. Tension: this would lead to the packages land in the sam. Outcome: I figured out later.

MATCHESSolution

Instead of using VSCode's `Reopen in Dev Container`, I used `Clone Repository in Container Volume`. Tension: an isolated Docker volume with no bindings. Outcome: pnpm was then happy to use parent directories for the store.

MATCHESSolution

Run vercel build --prod --token=***. Tension: Error: spawn pnpm ENOENT. Outcome: Install Vercel CLI.

MATCHESSolution

post-start failures. Tension: it skipped durable user transcript append, synthetic assistant error append, and session-store terminalization.

MATCHESSolution

How to fix this issue — Next.js project deployed on Vercel. Tension: SQLite is incompatible with serverless environments. Outcome: Consider cloud databases like Postgres Neon, Turso, or Vercel Postgres.

MATCHESSolution

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

MATCHESSolution

Failed to launch the browser process! — The application works correctly on my local but not on vercel. Tension: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory. Outcome: I have been able to fix this issue by changing the Node.js version to 18.x.

MATCHESSolution

I change config.yml and changed system.url-prefix: 'https:/IP' to system.url-prefix: 'https:/sentry.domain.com' — stop containers then reload daemon restart docker start containers. Tension: Origin checking failed - https://sentry-domain.com does not match any trusted origins. Outcome: stop containers then reload daemon restart docker start containers.

MATCHESSolution

Always run Uvicorn from project root:. Tension: Add `--reload-dir` for extra folders (like your SQL hooks):. Outcome: python -m uvicorn main:app --reload --reload-dir path\to\hooks.

MATCHESSolution

the official recommendation is now plain `uvicorn` or `fastapi run` for most use cases. — Starting with FastAPI 0.110. Tension: there's no need for Gunicorn. Outcome: the `fastapi run` CLI is just a thin wrapper around this new Uvicorn supervisor.

MATCHESSolution

Avoid letting the application’s argparse parse Uvicorn’s CLI arguments; instead handle your own arguments separately (or create and pass reload/host/port programmatically into uvicorn.run) so Uvicorn receives only its expected parameters.

MATCHESSolution

Outcome: CMD ["uv", "run", "retrofun.main:app_api", "--host", "0.0.0.0", "--port", "5555"].

MATCHESSolution

According to the FastAPI documentation about deploying FastAPI on Docker behind a proxy, you need to enable proxy headers. — if you're using it. Tension: Uvicorn (if you're using it) does not trust proxy headers by default unless specified. Outcome: Additionally, Starlette provides information about Uvicorn middleware for handling proxy header.

MATCHESSolution

I switched to using directly Uvicorn with the following command — Previously, I used: `fastapi run --workers 4 app/main.py`. Tension: the redirection then fails. Outcome: `uvicorn your_app:app --host 0.0.0.0 --port 8000 --proxy-headers --forwarded-allow-ips "*"`.

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

you might need to add the path to the module like so — Dockerfile. Tension: Depending on where your Dockerfile is in your structure, which is unclear. Outcome: CMD ["uvicorn", "backend.app.main:app", "--host", "0.0.0.0", "--port", "8000"].

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

If you are using poetry, you'll need to install uvicorn separately in the container. Outcome: you'll need to install uvicorn separately in the container.

MATCHESSolution

Run uvicorn binding to all interfaces (e.g., `--host 0.0.0.0`) and the correct port: `uvicorn main:app --host 0.0.0.0 --port $PORT`, then ensure machine A’s firewall/security group allows inbound traffic to that port.

MATCHESSolution

Use python -m uvicorn with the correct module path in ENTRYPOINT

MATCHESSolution

installing the obfuscator changes less often than building your project — Change the sequence so you have a container ready to build your project then obfuscate it. Tension: These are the last steps in the Dockerfile. Outcome: juggle commands that reveal same results to execute first.

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

As a workaround, you may consider running `grype` as the `root` user — please test it on an image that wasn't previously pushed to the Docker Hub. Outcome: docker run --rm --name grype -u 0 -v /var/run/docker.sock:/var/run/docker.sock anchore/grype:latest --only-fixed mirekphd/ml-cache:20230731.

MATCHESSolution

Stage 2 (startup). Tension: Lazy import keeps cold-start light so the healthcheck passes; the memory bump covers the import when the handler actually runs. Outcome: functions-framework can bind the port.

MATCHESSolution

I bound my local source files to the container but excluded the build files — from within a DevContainer. Tension: hot reload started working correctly. Outcome: hot reload started working correctly.

MATCHESSolution

check the container logs — When working with Docker and Django it's quite common to get things into a state where the container keeps restarting / won't really start. Tension: This usually indicates a problem in Django and the logs shows us what's wrong with it. Outcome: one will get a more specific error.

MATCHESSolution

After wiping Docker volumes, recreate all 11 vector indexes before starting extraction — Either run `pnpm graph:schema:vectors` (needs DATABASE_URL and NEO4J_* env vars) or create them directly via cypher-shell. Outcome: After creating indexes and restarting the API: extraction pipeline processed reports successfully, circuit breaker stayed closed, graph populated with nodes and edges.
