MinIO instead of Azurite for S3-compatible object storage locally and on Hetzner
Azurite ties the project to Azure Blob Storage. MinIO speaks the same S3 API as Hetzner Object Storage. Changing environment variables is enough to move to production. Alongside that: how the Zitadel bootstrap container creates OIDC apps automatically.
Event-driven ingestion with BullMQ and Redis
POST /ingest blocked the extension until embedding generation and the Qdrant upsert finished. BullMQ and Redis make ingestion asynchronous: an immediate 202, background processing and status queries through GET /captures/:id/status.
Vite build-time environment variables in Docker and why ARG is unnecessary
Vite embeds import.meta.env variables at build time instead of reading them at runtime. In Docker, this works through the build context, not ARG/ENV. A common mistake with a surprisingly simple solution.
Docker Compose override pattern for local development and Azure deployment
Most projects have one docker-compose.yml for local development and a completely different one for the cloud. That creates drift, errors and "works on my machine" problems. I show how the Docker Compose override pattern manages both environments with the same base files.
