The Great Drama As you know, Red Hat(actually IBM) decided to shoot itself in the foot again a month ago by closing the RHEL source code leaving downstream community/corporate based linux distros airless and causing great distress to many businesses and many people. If you wanna get a quick summary, I suggest reading Red Hat strikes a crushing blow against RHEL downstreams As a Fedora user, I have tried to sit back and relax and watch from a distant place to see if there were gonna be a decision to rollback on this decision but unfortunately, Red Hat press kept fueling the fire for a while, I also love to analyze fast decisions in the long term to see if it was really well-thought but I have to say, I was a bit Red Hat biased because of being a micro business owner and seeing many open source small businesses not making enough from what they provide to other people. ...

The Intro In this guide, I will be showing how to set up a simple Kubernetes(K3S) cluster which will have 1 master node and 2 worker nodes on Hetzner Cloud. My main goal is to make newcomers’ transition to Kubernetes very smooth as a person who suffered enough with complex tutorials/bills and didn’t get enough chance to poke a Kubernetes cluster. This tutorial should be applicable to any cloud provider but be warned pricing would be extremely different. If you come to learn Kubernetes, this could be your starting point to set up your own cluster and get started poking around with an actual production-ready cluster with k3s. ...

The Intro Hi everyone, this is the 2nd part of the series, we will be developing our API in this part. I will assume you have already followed the previous part and setup faasd and CockroachDB in your cloud server instance and have faas-cli in your both client computer and cloud server instance. I will also assume you have Go on your computer and a proper text editor. Let’s quickly get started. ...

The Series Intro Hi everyone, in this series we will be creating serverless highscore REST API in Go and utilize the most advanced and bleeding-edge open-source technologies such as Faasd(OpenFaaS engine) and CockroachDB(our cluster database). Keep in mind that we will actually need a server to do serverless computing :) (Plot Twist) In this 1st part, we will be setting up the infrastructure side for Hetzner Cloud with Terraform then in the 2nd part we will develop/deploy our functions with help of faas-cli. Faasd is developed by OpenFaaS to make self-hosted serverless functions much easier to develop/deploy without any vendor lock-in giant cloud company or K8s requirement. We will also be using CockroachDB as a single node database for our cloud server instance. There are some requirements but keep in mind that Terraform and Hetzner Cloud are not mandatory requirements. ...

The Intro Hello everyone, in this post I will be demonstrating how you can run localstack with Terraform and Docker and give you a proof of concept go application so you can tweak it according to your logic and follow anything you want to do such as integration/system tests for AWS services in your own CI/CD or localhost. Github Repository for PoC(proof of concept): hotdog-PoC-repository Requirements: Docker docker-compose Terraform Go aws CLI A bit of lambda, dynamodb and kinesis knowledge Localstack is a testing/mocking framework for developing Cloud applications locally. Where in theory, you can stick any AWS service and emulate them in localhost without ever needing the real AWS account. Localstack’s primary goal to make integration/system testing less painful for developers. ...
