Dear friend, you have built a Kubernetes, with Mac Chaffee

https://ku.bz/9nFPmG85f

Mac Chaffee, a platform engineer and security champion, examines why developers often underestimate the complexity of running modern applications and how overconfidence leads to expensive technical mistakes.

You will learn:

Why teams reject Kubernetes then rebuild it piece by piece - understanding the psychological factors, like overconfidence, that drive initial rejection of complex but proven tools

How to identify the tipping point when DIY solutions become more complex than adopting established orchestration tools, especially around scaling and high availability challenges

The right approach to abstracting Kubernetes complexity - why hiding the Kubernetes API often backfires and how to build effective guardrails instead of reinventing interfaces

Why mentorship gaps lead to poor technical decisions - how the lack of proper apprenticeship programs in tech results in teams making expensive mistakes when building infrastructure

My Workflow With AI: How I Code, Test, and Deploy Faster Than Ever

Discover how AI transforms software development workflows in this hands-on demonstration. Follow along as we explore a streamlined approach where AI agents generate detailed Product Requirement Documents (PRDs), manage tasks, write and test code, and automate complex development processes. Learn about the powerful combination of models, agents, MCP servers, and customized instructions that enable one developer to effectively orchestrate an entire AI-powered team.

This video showcases a practical, AI-driven workflow designed to simplify and accelerate software development, highlighting tools like Cursor IDE, Taskmaster, GitHub integration, and Memory MCP. Whether you're curious about AI-assisted coding or looking to enhance your own development practices, join us to see how Artificial Intelligence is reshaping the way we build software.

Week Ending June 15, 2025

https://lwkd.info/2025/20250617

Developer News

Kubernetes Slack is downgrading to a regular free account. Not only does this change how we use Slack, community members need to take action to preserve some things that are not part of regular backups.

The Go team fixed a symlink race condition in os.RemoveAll in Go versions 1.21.11 and 1.22.4. The Kubernetes Security Response Committee confirmed this vulnerability can allow file deletion on a Node. This issue will be fixed in the patch releases coming out on Wednesday

Release Schedule

Next Deadline: Enhancements Freeze, June 20

Hopefully everyone has their PRRs started, and this Friday is the deadline for opt-in for Enhancements. Get your 1.34 changes listed.

Kubernetes v1.34.0-alpha.1 has been built and pushed. Please review the changes and test the release.

Patch releases are due out on June 18th.

Featured PRs

132007: Fix: HPA suppresses FailedRescale event on successful conflict retry

This PR modifies the HPA controller to only emit a FailedRescale event if a scaling operation fails after retrying due to a conflict; If the retry succeeds, it will emit a SuccessfulRescale event instead. This change ensures that transient conflicts do not generate unnecessary failure events and reduces noise in the event logs.

132251: kubectl delete: update interactive delete to break on new line

This PR updates kubectl delete interactive mode to treat an empty newline as “No”. Previously, pressing “Enter” on an empty line would send a new line. With this update, pressing “Enter” now automatically responds with “No”, improving safety and ensuring that empty inputs don’t result in unintended actions.

KEP of the Week

KEP 2837: Pod Level Resource Specifications

The KEP extends the Pod API to support Pod-level resource limits and requests for non-extended resources in addition to existing container-level resource allocation. Previously, resource requests and limits could be set only at the container level, which limited flexibility and ease of resource management for the pod as a whole. The existing behaviour was problematic for users who wanted to limit the overall resource consumption of the entire pod.

This KEP is tracked for beta in v1.34.

Other Merges

kubernetes.io/initial-events-list-blueprint annotation removed from “Bookmark” event for watch stream requests

Missing conformance coverage for servicecidr read status endpoint

Go version for publishing bot rules updated

Support for API streaming from the rest client removed

Incorrect reference to JoinConfigurationKind in error message removed

Deprecated encryption config controller metrics removed

validation-gen code generator now generates validation code that supports validation ratcheting

Kubernetes is now built using Go 1.24.4

DRA kubelet: logging now uses driverName like the rest of the Kubernetes components

e2e tests for PodLifecycleSleepAction fixed to avoid flakes

Promotions

PreferSameTrafficDistribution to beta

NodeLocalCRISocket to beta

SeparateTaintEvictionController to stable

Subprojects and Dependency Updates

containerd v2.1.2 updates grpc to v1.72.2, fixes erofs error checks, improves mount error messages, updates image transfer logic, and prevents shim leaks

Beyond Kubernetes: Serverless Execution Models for Variable Workloads, with Marc Campora

https://ku.bz/5gMTkzLhV

Marc Campora, a systems consultant with experience in high-throughput platforms, shares his analysis of a real customer deployment with 500+ microservices. He breaks down the cost implications, technical constraints, and operational trade-offs between Kubernetes containers and AWS Lambda functions based on actual production data and migration assessments.

You will learn:

Cost analysis frameworks for comparing Lambda vs Kubernetes across different traffic patterns, including specific examples of 3x savings potential and the 80/20 rule for service utilization

Migration complexity factors when moving existing microservices to Lambda, including cold start issues, runtime model changes, and why it's often a complete rewrite rather than a simple port

Decision criteria for choosing between platforms based on traffic consistency, computational requirements, and operational overhead tolerance
