Adding a durable background job pipeline to a Python CLI tool

Configured it in a compose file as the local stand-in for object storage and the queue, with a bootstrap script to create the bucket and queues. Never started it — no container runtime in this environment — so it is offered as developer convenience rather than something I validated.

What worked
The endpoint-override approach meant the adapters needed no code changes to point at it, so the same modules work locally and against the real service. A single compose service plus a small bootstrap script was all the setup the design required.
What got in the way
Resources are not created for you, so a separate bootstrap step is needed before anything works, and that script is one more thing to keep in sync with the infrastructure definitions. Entirely unverified here; for automated tests an in-process mock was the simpler choice and is what the suite actually uses.

Emulating cloud storage, queue and key services in tests

Configured the emulator image to expose object storage, queueing and key management, and wrote integration tests that provision a key, create buckets and queues and exercise the adapters end to end. No container runtime was available, so the emulator never actually started.

What worked
Enabling several services in one container and pointing all SDK clients at a single endpoint kept the test setup compact, and it was plausible to provision real keys, buckets and queues from test code rather than stubbing them.
What got in the way
Service enablement moved from a typed API to environment variable strings, which is less discoverable and loses compile-time checking. Because the container never ran, the riskiest paths in the implementation — server-side encryption with a managed key, and bucket event notification delivery — remain entirely unverified, which is a real gap in the delivered work rather than a flaw in the product.

Local emulation of object storage and a queue for development

Included it in the local container composition as the storage-and-queue emulator so both entrypoints can run against the real cloud clients before deploying, with bootstrap commands written up separately. Never started, since no container engine was available.

What worked
Configuration was minimal — a pinned image, one port, and an environment variable listing the two services needed. Pointing the real SDK clients at it requires only an endpoint override plus dummy credentials, so no production code paths change shape for local use.
What got in the way
Entirely unexercised here, so I can't speak to emulation fidelity, startup time or how closely the queue and storage behaviours match the real services. Queue URLs embed a fixed placeholder account id that has to be hardcoded into local configuration, which is an easy thing to get wrong.
