GitOps: How To Use _ (Not YAML) To Manage Kubernetes Resources With GitOps?

Today, we tackle a viewer question on using formats other than YAML to manage Kubernetes resources with GitOps tools like Argo CD and Flux. Learn how to effectively use Helm, Kustomize, CUE, KCL, ytt, and more to define your desired state in YAML. We'll explore workflows, best practices, and how to ensure smooth synchronization of your configurations. Leave your questions in the comments and join our community!

Jeff Bezos, Elon Musk and the Billions of Ways to Influence an Election

Entrepreneurs become legends when they make big bets on technology that pay off in a huge and dramatic way. Elon Musk is now applying that all-or-nothing philosophy to a presidential election, tying his reputation and perhaps his future to a win by Donald J. Trump.

Release Schedule

Next Deadline: Feature Blog Freeze, October 30

We are in the countdown to Code Freeze and this week is full of deadlines. Finish your feature blog entries by October 30, followed by any major deprecations/removals by November 4, with Code and Test Freeze on November 8th.

Featured PRs

125258 Etcd Kubernetes interface

Introduces the alpha version of a defined interface for Kubernetes-etcd communications. The interface will improve tests and reliability as well as permitting (but not implementing) alternate backends. It covers data storage and leases.

KEP of the Week

KEP-1847: Auto delete PVCs created by StatefulSet

The KEP implements automatic deletion of “Persistent Volume Claims (PVCs)” associated with StatefulSets upon their deletion or scale-down. It introduced a PersistentVolumeClaimRetentionPolicy field, allowing users to opt-in for PVC deletion. This enhancement simplifies resource management, while preserving application state during regular operations.

This KEP is tracked for stable release in the ongoing v1.32 cycle, but is considered “at risk” because it is missing requirements for Code Freeze.

98% faster data imports in deployment previews, with Nick Nikitas

https://kube.fm/deployment-previews-nick

Are you facing challenges with pre-production environments in Kubernetes?

This KubeFM episode shows how to implement efficient deployment previews and solve data seeding bottlenecks.

Nick Nikitas, Senior Platform Engineer at Blueground, shares how his team transformed their static pre-production environments into dynamic previews using ArgoCD Application Sets, Wave and Velero.

He explains their journey from managing informal environment sharing between teams to implementing a scalable preview system that reduced environment creation time from 19 minutes to 25 seconds.

You will learn:

How to implement GitOps-based preview environments with Argo CD Application Sets and PR generators for automatic environment creation and cleanup.

How to control cloud costs with TTL-based termination and FIFO queues to manage the number of active preview environments.

How to optimize data seeding using Velero, AWS EBS snapshots, and Kubernetes PVC management to achieve near-instant environment creation.
