Moving Logic Out of Pods: Extending the Argo Workflows Controller
https://hackernoon.com/moving-logic-out-of-pods-extending-the-argo-workflows-controller
In this article, I'll show how the Argo Workflows Executor Plugin lets you extend the Argo Workflows controller without maintaining your own fork—simply by implementing a small HTTP server in any language. As a bonus, this same mechanism reduces the number of extra pods in your DAGs and lightens the load on the Kubernetes scheduler. If you're new to Argo, I'll briefly cover the architecture and where plugins fit in. We'll finish with practical examples and key configuration details.

The Invisible Rewrite: Modernizing the Kubernetes Image Promoter
https://kubernetes.io/blog/2026/03/17/image-promoter-rewrite
Every container image you pull from registry.k8s.io got there through kpromo, the Kubernetes image promoter. It copies images from staging registries to production, signs them with cosign, replicates signatures across more than 20 regional mirrors, and generates SLSA provenance attestations. If this tool breaks, no Kubernetes release ships. Over the past few weeks, we rewrote its core from scratch, deleted 20% of the codebase, made it dramatically faster, and nobody noticed. That was the whole point.

How Mastodon Runs OpenTelemetry Collectors in Production
https://opentelemetry.io/blog/2026/devex-mastodon
At the beginning of 2025, the OpenTelemetry Developer Experience SIG published the results of its first community survey. One of the strongest themes was clear: teams want more real-world examples of how the OpenTelemetry SDKs and the OpenTelemetry Collector are actually used in production.
To help close that gap, the SIG began collecting stories directly from end users—across industries, architectures, and company sizes. This post kicks off a new series focused specifically on organizations’ real world stories, starting with a small but uniquely challenging case.
This first story features Mastodon, a non-profit organization operating at global scale with a remarkably small team.

Practical Considerations for AI Incident Reviews
