Production-ready Flask & Django apps on Kubernetes
summary
Explains exactly how to run Flask/Django WSGI apps on Kubernetes: use a sidecar nginx proxy (or async Gunicorn/uvicorn workers or a service mesh) to protect and buffer requests; serve static files either via sidecar volume, S3 with django-storages, or preferably WhiteNoise for static files; deploy with Kubernetes Deployments (example shows three replicas) and run schema changes with a Kubernetes Job for migrations; store config in ConfigMaps but store credentials with Secrets or an external Vault; ASGI (uvicorn/daphne) is presented as the future.
