AntiPattern

Startup and CLI Entrypoint Drift

asgi-entrypoint-drift

Application startup fails because container entrypoints and runtime initialization disagree: module paths, CLI argument ownership, multiprocessing/reload semantics, and event-loop bootstrapping conflict with the ASGI server (Uvicorn) expectations, yielding import errors, hangs, or wrong process behavior.

MATCHESSolution

Pin the provider backend command to the absolute standalone CLI path with a persistent service startup patcher, then restart the gateway and verify the child process command path and transcript version.

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

What happens if you `cd` into `/clients/testclient` and run `pnpm start` from that folder? — Turbo starts the development server without issues. Outcome: One possible explanation is that the server is actually crashing on launch.

MATCHESSolution

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

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

Removing the calls to `process.exit()` — writing a CLI command in NestJS. Outcome: letting the command finishes normally resolves the issue.

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

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

Move the initialization of `qdrant_client` into lifespan. Outcome: override using standard FastAPI mechanism.

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 can benefit from the lazy initialization inside the `startup` event. Outcome: async def startup_event(): await SINGLETON.initialize().

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

Initialize Eureka using the async API (e.g., `eureka_client.init_async(...)`) and/or move initialization into an appropriate async startup hook so it doesn’t start a new event loop at import time.

MATCHESSolution

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

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

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

starting the debugging process by exploring the Expo router file — The error message only points to the entry.js file. Tension: Could this problem be cause d by something in my code, or is it more likely related to something else? Outcome: That was exactly where the bug was.

MATCHESSolution

Wrap process.stdout.write at the very start of the entry file — at the very start of the entry file. Tension: This is a sledgehammer — only use when you cannot fix the offending dependency.

MATCHESSolution

Separate the Django web server and Celery worker into different containers or services

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

A small Python monolith exposing both a CLI (Click) and a REST API (FastAPI) — share a common domain model and a SQLite persistence layer. Outcome: share a common domain model and a SQLite persistence layer.

MATCHESSolution

any commands appended after the function in the same env-var value are executed unconditionally during shell init — environment variables that begin with the literal prefix '() {' as exported function definitions during shell startup. Tension: Env vars are routinely populated from untrusted sources. Outcome: pre-auth RCE.
