Jenkins on Arch Linux: How I Set It Up on i3

Mon, 09 Feb 2026 00:00:00 +0000

Why I Wrote This

I run Arch Linux with i3 and wanted Jenkins locally for CI/CD experiments. This covers Java 21, the Jenkins install, a test job, and a GitHub pipeline — exactly what I ran on my machine.

1. What is Jenkins? (Simple Explanation)

Jenkins is an automation server.

You can tell Jenkins to:

Get your code (for example from GitHub)
Run commands (build, test, scripts)
Show you if things passed or failed

Instead of you running commands manually every time, Jenkins does it automatically.

Ollama + DeepSeek: How I Run LLMs Locally

Mon, 03 Feb 2025 00:00:00 +0000

Why I Use Ollama

I wanted to run LLMs on my own hardware without paying for API calls or sending data to the cloud. Ollama made that straightforward — install, pull a model, start chatting.

Install Ollama

Arch Linux

Update your system, then install Ollama:

sudo pacman -Syu
sudo pacman -S ollama

Enable and start the service:

sudo systemctl enable ollama
sudo systemctl start ollama
sudo systemctl status ollama

You should see active (running).

Creating My First Docker Container

Wed, 27 Jul 2022 00:00:00 +0000

What I Did Here

After installing Docker, I wanted to run an actual Ubuntu container — not just hello-world. The steps inside this post are the same on Arch Linux and Ubuntu hosts. Only the Docker installation differs — see Docker on Arch Linux and Ubuntu for that part.

Arch Linux (host)

Make sure Docker is installed and running on your Arch machine first:

sudo pacman -S docker
sudo systemctl enable --now docker
systemctl status docker

Pull the Ubuntu image

sudo docker pull ubuntu

Create and enter a container

sudo docker run --name my-container -it ubuntu

What those flags mean:

Docker on Arch Linux and Ubuntu: How I Got It Running

Tue, 26 Jul 2022 00:00:00 +0000

Why I Started Using Docker

I wanted a way to run apps without messing up my main system. Docker packs an app with everything it needs into a container — a small, isolated environment that shares my kernel but stays separate from everything else.

If something breaks inside a container, I delete it and start over. No reinstalling the whole OS.

Containers vs Images (Quick Version)

Image — a read-only template (like a recipe)
Container — a running instance of that image (like the actual dish you cooked)

You build or pull an image once. You can spin up as many containers from it as you want.

SSH: How I Connect to Remote Servers

Sat, 14 Aug 2021 00:00:00 +0000

Why I Use SSH

SSH is how I control another machine from my terminal. I use it to manage servers, copy files, and run commands on remote systems without sitting in front of them.

For Windows remote desktop you use RDP. For Linux, SSH is the standard.

How SSH Works (Short Version)

Client — on your laptop (where you type)
Server — on the remote machine (what you connect to)

You run ssh user@ip, enter your password (or use a key), and you get a shell on the remote box.
