DevOps Learning Notes

Build a minimal Go HTTP server from scratch that follows North American industry standards, covering project structure and chi router usage

My background is as a .NET Engineer, so these notes use .NET analogies to help clarify Go’s design choices

If you also come from a .NET background, these comparisons should be helpful

The cmd/ Directory

Go requires every executable program to have a package main and a main() function. cmd/ is a Go community convention for organizing the entry points of binaries this repo will produce

This post is the complete record of placing Ubuntu 24.04 Minimal Server into a KVM/libvirt default NAT network — going from “apt update completely fails” to “Docker Engine running normally” — a deployment walkthrough you can follow step by step.

The focus is not just providing a set of commands, but documenting every checkpoint clearly, to avoid getting stuck at the same place when rebuilding the environment later.

Setting Up the Virtualization Server (Arch-Derived)

First, install virtualization and networking packages on the Host.

This post is a full record of the issues and implementation details I hit while configuring container output collection on EC2 in a real environment.

Why central remote logging is worth it

Before this setup, checking container output always meant SSH into EC2 and running docker logs. Once environments grow (staging + prod), that becomes hard to manage. A centralized stream lets you inspect output in AWS Console or CLI directly, without SSH on every check.

Installing the CI Executor

The installation procedure varies by environment. This section covers Windows and Docker.

Using an External Relational Database with the Platform

Introduction

Due to a recent project requirement, I researched how to configure an external PostgreSQL instance. The setup is similar across old and new versions, though some commands have changed.

First Look: Enterprise Edition via Containers

Introduction

A recent project required a self-hosted Git platform, so I researched how to set it up. The client was on an older version, so I had to work with that initially — but the workflow is essentially the same across versions; only the UI differs.
