This is rather short note on how to do the certification rotation, as official istio documentation is really sparse on details. 
 This has been tested on Istio 1.28.1, in Kind cluster, running ambient mode with ztunnel and waypoints. 
 Issue I’ve been facing was that whenever I tried to replace the CA Certificates used by istio, Istio Waypoints were unable to communicate with Istio…
Something that has been bothering me for a while and I’d really like to put it in writing. 
 I believe that LLM based AI is going to negatively impact an ability for a person to become an expert at anything. 
As an effect of that, a negative feedback loop is going to form where AI will become dumber and dumber.
You can’t have LLM learn more and yet destroy the whole…
Buying a new AP to cover more space 
 So I recently moved to a new flat. This was a significant upgrade for me,
since before I was living in almost 40m 2 and a single AP was enough. 
 However, once I moved to almost 80m 2 - it turns out single AP cannot
cover 5GHz for the whole flat, so I had to buy another one. 
 I wanted to buy something cheap & reliable. I came across…
Mind you, this is kind of a clickbaitish, but what I mean exactly is that traefik is too complicated for personal k3s setup. 
 Trying to setup traefik from scratch 
 I’ve been working on setting up traefik from scratch as an exercise. I got to the point where it’s all nice and running and then there is this. 
 I’ve created IngressRoute

This is gonna be rather short. I wanted to put all the info I gathered in a single place. 
 Dockerfile 
 There is no official docker image available yet. There is however official Dockerfile which you can use to base your setup off of.

 You need to modify it slightly however

I hate Helm 
 I truly hate helm. It’s not because it’s a bad idea, core idea of Helm does actually solve a problem that you often meet with deploying manifest (customization). It’s not because I don’t know how to use it - I used it to create many deployments and I truly appreciate its existence. 
 But I hate it to the heart. 
 Why you might ask? 
 It’s…
How does it work without Flannel 
 Assumption: I’m using host networking through these examples. You could utilize docker network for example, but to make it simple I wanted to stick to the fact below 
 container network = host/node network 
 If there was no Flannel, connection between containers would need to happen by directly connecting to the specific port that container is…
Long time ago I bought a tablet Lenovo A3500-FL .
It’s really old tablet but still works suprisingly well. I thought about maybe having it working as a mobile terminal or Home Assistant Dashboard . 
 It only has offical upgrade to Android 4.4.2 which is really old and applications might not be targeting it anymore. According to XDA article only 4% of devices are still running Android…
I’ve always wanted to have my own home server. I’ve even bought Intel NUC for that which I intended to use, but I never got around to configuring it properly so it has gathered dust while not in use. 
 But in motivation strike, I decided to finally get around to do it, and implement it. 
 Infra automation not always the best way to move forward 
 First of all, I don’t…
There are things that I enjoy when working as a professional.
One of them is that when the tooling is so good that it just makes want to write the code.
Example of state-of-the-art integration of IDE into a language is what Hashicorp has done to the Terraform and its integration with IntelliJ IDEA. 
 An example of that you can find below 
 
 Autocomplete works out of the box,…
UPDATE (2021-08-06): In a hindsight I think I choose wrong title to describe the concept. More appropriate would be “Modern infra automation state management is gateway drug for using more cloud provided services” or something along these lines. Initial thought on title came from the fact that I considered terraform/pulumi to be truly “Infra as a code” solution, while…
Intro 
 For unfamiliar with Polish economy 
 For the context of this post - I currently live by renting a flat in Warsaw, almost by the city border (Far end of Ursynów district). See the attached view for having a context 
 
 Here is how it looks like 
 
 
 I’ve pretty close connection to metro line (which to say is impressive here as Warsaw has only two metro…
Interactive terraform console UI for managing state (mainly renaming variables)
After spending a couple of days laying in my bed with absolute no motivation at all to do anything I’ve decided to do anything that will bring me from the lair of despair. 
 COVID situation here in Poland at the moment of writing the post is not really great, there is absolutely nothing to do outside because everything is cancelled. 
 I can either tinker in my “electronic…

My attempt to make alternative for hosting 3D printing content (*.stl)
When I was writing a tutorial regarding usage of VirtualBox to compile Marlin firmware (for 3D Printers) I came across following issue:

This is my first blog post about running anything related to home lab.
As I have already done some work before to have Proxmox VE running with connection to the router —
I will be explaining that in later posts if I find time or motivation to do so. 
 Planned : 
 
 I want to have 3 nodes of VM, with Ubuntu Server running on them, referring to them as Swarm Nodes. 
 I will…
