What’s New in Cloud‑Native Tech? Golang 1.14, Cilium 1.7, K8s PRs, Eventing Roadmap & More
This roundup highlights the latest cloud‑native developments, including Golang 1.14’s production‑grade module support, Cilium 1.7’s networking enhancements, critical Kubernetes PR fixes, the Eventing 2020 roadmap, a new open‑source supply‑chain tool, and several recommended technical reads.
Golang 1.14 Release
Golang 1.14 has been released, bringing production‑grade go module support, improved defer performance, and preemptive goroutine scheduling.
Cilium 1.7 Release
Cilium, an open‑source project that transparently provides and secures network and API connections for applications running on container platforms such as Kubernetes, is now at version 1.7.
Kubernetes Upstream Updates
Honor status.podIP over status.podIPs when mismatched – This PR fixes compatibility between older Pod APIs and newer API server versions; users of Kubernetes 1.15 and earlier should urgently port the change to avoid status update failures.
Adding AppProtocol to Services and Endpoints – The new AppProtocol field allows specifying application‑layer protocol names for each Service port, improving readability compared to the previous TCP/UDP only identification.
Promote the EgressSelector API to beta – The EgressSelector API moves from alpha to beta, indicating a more stable definition and implementation.
Eventing 2020 Roadmap
The roadmap for Knative Eventing in 2020 includes:
Support for V1 APIs
Production‑ready broker
Data‑plane security policies
Serverless‑style data‑plane scalability
Autoscaling of Eventing Components
The community has submitted a PR to enable automatic scaling of Eventing components using a KEDA‑based plugin, deploying the components as Knative Services.
Open‑Source Project Recommendation: rode
Rode builds a trusted software delivery chain on Kubernetes. It aggregates software lifecycle and release events into the Kubernetes system, registers them in Grafeas, and can intercept illegal application instance creation at the cluster entry point.
Reading Recommendations
Continuous Integration for Helm Charts – Describes how to integrate Helm chart publishing into a CI pipeline for automated application delivery.
In‑Depth Tcpdump Guide – Provides a comprehensive tutorial for using tcpdump to diagnose network connectivity issues in services.
Serverless Workloads in Kubernetes with KEDA – Introduces KEDA, an event‑driven autoscaling tool for Kubernetes that is vendor‑neutral and can be deployed on any cluster.
