Tutorial: Workshop: Developing as a Team for Kubernetes With Nix and Flox
Talkat KubeCon + CloudNativeCon Europe 2025 · on Friday, 2025-04-04· at 11:00· Level 1 | Hall Entrance N11·
summary
Workshop shows a concrete pipeline: a Go + ImageMagick + Postgres app built from a checked-in Flox environment, activated with flux activate, and run locally inside GitHub Codespaces; Postgres is provisioned from a copied Flux env and the app is containerized with flux containerize or a Dockerfile that pulls hashed Nix store paths into a multi-stage image. Demos hit a FluxHub 503 but the local build, database init, and Kubernetes YAML all work, proving cross‑platform reproducible dev → container → GitOps deployment.
