Container Entrypoint Import Failures

asgi-entrypoint-config-mismatch

Uvicorn/ASGI startup inside containers fails because the entrypoint points at the wrong module or the runtime environment intercepts startup arguments, producing missing-app errors and hung requests due to network/loopback binding mismatches.

`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

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

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

Inside Alembic's `env.py`, you can swap out the default engine — If you do not wish to run it from the command line. Tension: I did not document how to connect with google connector. Outcome: call its migration API inside your application.

MATCHESSolution

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

MATCHESSolution

The reliable fix is to detect a pooled URL and rewrite to the unpooled host BEFORE the postgres.js client is initialized — For backfill / admin scripts (Drizzle paths). Tension: postgres.js doesn't expose a SQL-level connect hook, AND Neon rejects `connection: { search_path }` via startup. Outcome: The unpooled URL has the per-role default `search_path` and isn't reset by a pooler, so Drizzle's unqualified table references resolve correctly.

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

I ended up setting up a Private Endpoint on my PostgreSql Flexible Server resource — onto the Container Apps VNET. Tension: thus giving access from CAE to Postgres. Outcome: I can then turn off Public Access to Postgres.

MATCHESSolution

You have to change the docker entrypoint command like below to use a custom `vault.hcl` file. — Example `docker-compose.yaml` file. Tension: it just always seems to want to find a local.json file. Outcome: entrypoint: vault server -config=/vault/vault.hcl.

MATCHESSolution

Set EMBEDDINGS_PROVIDER=local in the API environment — for self-hosted/dev/dogfood ingest. Tension: do not rely on a 'local default'. Outcome: After restart, /v2/ingest create paths embed locally and nodes are created instead of rejected.

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

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

Open "Inbound". Tension: either a rule that allows java.exe to receive packets. Outcome: or a rule that allows packets to be received to the specific UDP port irrespective of the program.

MATCHESSolution

Restored the gateway to bind on loopback and enabled its Tailscale Serve mode — so the persisted Serve route and the application listener matched. Tension: the persisted Serve route and the application listener matched. Outcome: Restarted the user service, which re-ran `tailscale serve --bg --yes <port>` and exposed the UI at the HTTPS tailnet hostname.

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

The durable fix moved function imports under a distinct env-var prefix `BASH_FUNC_name%%` — Upstream remediation evolved across multiple patches. Tension: ad-hoc string checks proved insufficient. Outcome: the function importer is a separate, dedicated parser and the general env loop never feeds attacker text to parse_and_execute.
