Real-world experiences, lessons learned, and technical insights from building production infrastructure. Stories from the trenches of DevOps, Kubernetes, cloud platforms, and platform engineering.
GKE - Part 7: Build Once, Promote Forward with Kargo
How Kargo fits into a GitOps platform built around immutable artifacts, Argo CD, and environment promotion.
GKE - Part 6: Multi-Cloud Service Connectivity Between GKE and EKS
Connecting workloads across GKE and EKS with the Tailscale Kubernetes operator, so a workload moved to GKE can still reach a private service in EKS.
Using ADB as My Android File Manager from Linux
I wanted to move files to Android without installing a random file manager app, so I started using ADB from my Linux terminal instead.
GKE - Part 5: Private Platform Access with the Tailscale Kubernetes Operator
Installing the Tailscale Kubernetes operator on GKE, exposing Argo CD privately through Tailscale Ingress, and documenting the setup so I do not have to rediscover it next time.
GKE - Part 4: ExternalDNS, cert-manager, and Real URLs for the GitOps Platform
Adding the platform services that turn Gateway API from a manually wired entry point into a DNS and TLS managed edge for GKE.
GKE - Part 3: From Local Terraform to CI: Structuring Shared and Nonprod Stacks for GKE
Moving a Terraform-first GKE setup from local execution to CI, and organizing shared and environment stacks to make the system repeatable and extensible.
GKE — Part 2: Private Nodes, Gateway API, and a More Realistic Cluster Shape
Evolving a Terraform-managed GKE cluster from a public proof of concept into a more structured setup with private nodes and a defined entry point.
From Zero to GKE — A Terraform-First Build with Production in Mind
A Terraform-first journey into GCP and GKE—bootstrapping remote state, building a clean foundation, and getting a minimal cluster running with a clear path toward production.
How to Build a Slack Bot Like Doraemon
A practical walkthrough on building a Slack bot using Socket Mode and Python 3.11, based on a real-world project.
From x86 to ARM in production: the EKS migration story
We migrated our EKS workloads from x86 to ARM in production with zero downtime. Here's how we simplified our architecture story end-to-end and saved cost without trading away reliability.
Building a New Portfolio Page: Migrating from MkDocs to Astro
Journey of creating a new portfolio page by converting a MkDocs-based documentation site to Astro, focusing on creating dedicated sections for content series like DevOps Odyssey with custom layouts.
Build Once. Promote Forward. Ship Daily.
How we eliminated rebuild-per-environment pipelines and went from shipping every two weeks to shipping daily. A real-world story of building once, validating once, and promoting the same artifact through environments.
