&lt;p&gt;This post walks through bringing up a local Kubernetes cluster. Managed offerings such as EKS, GKE, and AKS are the obvious choice for production workloads, but the recurring cost makes them impractical for everyday experimentation. As a more economical alternative, we will stand up a single-node cluster on a personal machine — a setup that is more than sufficient for the kind of iteration we need.&lt;/p&gt;</description></item><item><title>[KR] Envoy Proxy 기여 여정 #2: 빌드 환경 구축 - 1</title><link>https://qerogram.github.io/posts/envoy_series/week_2/</link><pubDate>Sun, 14 Jun 2026 12:00:00 +0900</pubDate><guid>https://qerogram.github.io/posts/envoy_series/week_2/</guid><description>&lt;div class="custom-series-banner"&gt;

일반적인 쿠버네티스 서비스를 이용하기에는 많은 비용이 들기 때문에, 우리는 비용 문제로 인해 로컬에서 테스트해볼 수 있는 단일 노드(PC)의 쿠버네티스를 구축하고자 한다.&lt;/p&gt;</description></item><item><title>[EN] Contributing to Envoy Proxy #1: Setting Up the Development Environment</title><link>https://qerogram.github.io/posts/envoy_series/week_1en/</link><pubDate>Sun, 31 May 2026 22:00:00 +0900</pubDate><guid>https://qerogram.github.io/posts/envoy_series/week_1en/</guid><description>&lt;div class="custom-series-banner"&gt;

&lt;h1 id="introduction"&gt;Introduction&lt;/h1&gt;
&lt;p&gt;As we begin this series, you&amp;rsquo;re likely already familiar with how remarkable Envoy Proxy is. It serves as a de facto standard proxy even in Istio environments and stands as one of the most mature and production-ready proxies available today. Envoy is the third CNCF project to achieve &lt;code&gt;Graduated&lt;/code&gt; status.&lt;/p&gt;</description></item><item><title>[KR] Envoy Proxy 기여 여정 #1: 개발 환경 구축</title><link>https://qerogram.github.io/posts/envoy_series/week_1/</link><pubDate>Sun, 31 May 2026 22:00:00 +0900</pubDate><guid>https://qerogram.github.io/posts/envoy_series/week_1/</guid><description>&lt;div class="custom-series-banner"&gt;

&lt;p&gt;본 시리즈를 시작하며, Envoy Proxy가 얼마나 대단한 지는 다들 아실거라고 생각합니다.
Istio환경에서도 실질적으로 표준에 준하는 Proxy이자, 굉장히 성숙도가 높은 Proxy입니다.
CNCF의 3번째 &lt;code&gt;Graduated Project&lt;/code&gt;입니다.&lt;/p&gt;</description></item><item><title>[EN] Contributing to Envoy Proxy: A Journey with Redis Integration</title><link>https://qerogram.github.io/posts/envoy_series/week_0en/</link><pubDate>Tue, 19 May 2026 22:00:00 +0900</pubDate><guid>https://qerogram.github.io/posts/envoy_series/week_0en/</guid><description>&lt;div class="custom-series-banner"&gt;

Rather than theoretical knowledge, this series shares practical experience from a real-world production scenario.&lt;/p&gt;</description></item><item><title>[KR] Envoy Proxy 기여 여정</title><link>https://qerogram.github.io/posts/envoy_series/week_0/</link><pubDate>Tue, 19 May 2026 22:00:00 +0900</pubDate><guid>https://qerogram.github.io/posts/envoy_series/week_0/</guid><description>&lt;div class="custom-series-banner"&gt;
