Simplifying Python Web App Operations: Automating K8s Ops with Open Source
summary
A simple Flask app is containerized two ways (handwritten Dockerfile and Canonical’s rockcraft) and deployed via Helm charts, fly.io, and Juju onto microk8s; rockcraft produces production-ready OCI images and the handwritten/generated Dockerfiles run the Flask dev server so they require hardening. fly.io builds and serves the app quickly but its Dockerfile isn’t production-ready. Juju deploys app plus Postgres and Ingress automatically, runs migrations, and the demo shows requests incrementing a visitor count successfully.
