Kubernetes
The de-facto container orchestration platform and the substrate of most modern platform-engineering. In this wiki it appears not as a tutorial subject but as the operational reality teams run in production — the assembly point for the wider CNCF ecosystem (Prometheus, Cilium, cert-manager, Cluster API, GitOps).
In the sources
kubernetes-integration-tax is the anchor: production Kubernetes is dominated by the hidden labour of integrating its surrounding tools, not by Kubernetes itself. This is where the observability stack (Prometheus + Cilium metrics) and networking (NetworkPolicies, ingress) actually have to be wired together.
Adjacency
Kubernetes-as-a-rented-service (managed K8s pricing) would belong in cloud-wiki,
but the platform-ops practice of running it in production lives here.
