Kubernetes and Taxes: Lessons Learned at the Norwegian Tax Administration - Bjarte S. Karlsen
summary
Organization migrates 100s of apps onto six OpenShift clusters over 2½ years to get faster development and more efficient ops, running all new tax apps since 2016 and keeping stateful Oracle systems outside the clusters. CI uses containerized Jenkins + Bitbucket hooks, Nexus and Docker registry, image streams that push multiple tags (one tag per build) so patching and zero‑day fixes roll out automatically. Built a Git‑backed Aurora config, AO CLI, console and an Ops “wallboard”; most apps are stateless and the platform is working in production. Docker + Java proved surprisingly hard and external integrations (Splunk, firewall) took years to automate.
