Cloud‑Native News: CNCF Election, 2020 Report, Tekton Outlook, Scheduler Fixes

Industry News

CNCF TOC 2020 Election Results

On 3 February 2020, the Cloud Native Computing Foundation (CNCF) held its Technical Oversight Committee (TOC) election, adding five new members: three nominated and voted by the Governing Board, one by maintainers, and one by the end‑user community.

CNCF 2019 Annual Report Highlights

173 new CNCF members joined in 2019, a growth of over 50%.

Attendance at KubeCon events reached 3,500 in Shanghai, 7,700 in Barcelona, and 12,000 in San Diego.

Six projects (CoreDNS, containerd, Jaeger, Vitness, TUF) graduated; three projects (CloudEvents, Falco, OPA) entered incubation; an additional twelve projects entered the Sandbox.

Tekton 2020 Outlook

Tekton, Google’s open‑source cloud‑native CI/CD system, released nine versions (0.1.0 – 0.9.2) in 2019 and plans to ship a Beta of Tekton Pipeline in 2020.

Upstream Important Changes

Support server‑side dry‑run in cli‑runtime REST Helper

Server‑side dry‑run is now available for more kubectl commands beyond kubectl apply.

Fix back‑off when scheduling cycle is delayed

When a pod is unschedulable and its backoff exceeds maxDuration, the scheduler previously cleared the backoff, causing possible starvation of lower‑priority pods. The fix now clears the backoff only after 2 × maxDuration.

Fix missing scheduler metrics (pending_pods and schedule_attempts_total)

A bug in Kubernetes v1.17 prevented the pending_pods and schedule_attempts_total metrics from being recorded; this has been corrected.

Context support in k8s.io/client‑go

The client‑go library now accepts an external context.Context, enabling timeout/cancel handling and future distributed‑tracing support.

ctx := req.Context()
pod, err := k8client.CoreV1().Pods(namespace).WithContext(ctx).Get(podName, …)

Multi‑Scheduling Profiles

Instead of running multiple scheduler binaries for different workloads, a single scheduler binary can host multiple framework instances, each with its own profile while sharing the same node/pod cache.

Open‑Source Project Recommendations

kube‑scan : evaluates Kubernetes workloads against the KCCSS rule set and provides a security‑risk rating.

permission‑manager : SIGHUP’s RBAC management tool that creates users, assigns namespace or global permissions, distributes kubeconfig files, and offers a user‑friendly UI.

kubectx : a utility for quickly switching kubectl contexts, simplifying operations in multi‑cluster environments.
