Each cluster runs its own Argo CD for GitOps application management, while Doppler and External Secrets supply credentials and persistent workloads stay on Proxmox.https://phuchoang.sbs/projects/refurbished-marketplace/Sun, 29 Mar 2026 00:00:00 +0000xuanphuc.a1gv@gmail.com (Felix Hoang)https://phuchoang.sbs/projects/refurbished-marketplace/This project explores distributed Go microservices through a refurbished-goods marketplace, with a server-rendered storefront, catalog search, inventory reservations, and merchant-scoped checkout. It combines gRPC APIs, Kafka and Debezium messaging, a durable checkout saga, and Argo CD deployments on Talos Kubernetes with Istio ambient mTLS and OpenTelemetry observability.https://phuchoang.sbs/posts/gitops-github-actions-terraform-ansible/Mon, 17 Nov 2025 00:00:00 +0000xuanphuc.a1gv@gmail.com (Felix Hoang)https://phuchoang.sbs/posts/gitops-github-actions-terraform-ansible/<p>This is Part 2 of the Hashicorp Vault series.

To think that half of the internet relies on a single service is crazy, even if it might be the best in its field. The engineers at AWS have done many things to prevent this, such as high availability, multi-region, zones, etc., but if a critical part of it still goes down, the whole thing goes down too. Therefore, if you don&rsquo;t want to give all your money and trust to a single company, you might want to explore the on-premise option, which is self-hosting.</p>https://phuchoang.sbs/posts/self-hosted-network-design/Mon, 27 Oct 2025 00:00:00 +0000xuanphuc.a1gv@gmail.com (Felix Hoang)https://phuchoang.sbs/posts/self-hosted-network-design/<p>A long time ago, my house only had 1 router, located on the third floor. So whenever we needed to access the internet while having dinner on the first floor, we needed to enable 4G or walk near the stairs just to receive a fraction of the WiFi signal. My father decided to give me an important task, which was to figure out how to solve this issue. I initially bought a simple WiFi extender located on the second floor, but after using it for a month, even though we could receive a strong signal from it, we couldn&rsquo;t access the internet because the signal from the router on the 3rd floor to the WiFi extender on the 2nd floor was still really weak.</p>https://phuchoang.sbs/posts/self-hosted-network-design/Mon, 27 Oct 2025 00:00:00 +0000xuanphuc.a1gv@gmail.com (Felix Hoang)https://phuchoang.sbs/posts/self-hosted-network-design/<p>A long time ago, my house only had 1 router, located on the third floor.

When I booted it up, it said something like, <code>fTPM is corrupted, press Y to reset or N to do nothing</code>. Neither of them helped me boot into my machine. So I had a severe mental attack back then, because that machine was the primary one that helped me do my work for school, my lab, and my personal projects. I was lucky to have my friend lend me an old laptop of his, but it was pretty bulky, so I figured I couldn&rsquo;t bring it to school.

That was me—desperately trying to read intimate and underrated series that weren’t even on MangaDex, likely due to copyright issues.</p>https://phuchoang.sbs/posts/self-hosted-initial-story/Sun, 27 Aug 2023 00:00:00 +0000xuanphuc.a1gv@gmail.com (Felix Hoang)https://phuchoang.sbs/posts/self-hosted-initial-story/<p>It all started with a computer my mom saved from the trash heap at her office. It was a standard HP Prodesk 600 G4—nothing special, and since I already had a PC and a laptop, I had no idea what to do with it. Just installing Windows on it felt like a waste. I knew it could be something more than just another desktop collecting dust.</p>
