Why Linux 🐧? the question isn’t why Linux ? the real question is why not ? did you try it?

Linux is widely regarded as the best option for development, DevOps, hybrid cloud solutions, and even as a desktop for home and office environments due to its open-source nature, robust ecosystem, scalability, security, and cost-effectiveness. Its flexibility allows seamless integration across diverse platforms, from small IoT devices to large-scale cloud infrastructures, making it the backbone of modern technology stacks.

Creating snapshot image in Hetzner with packer

Tue, 20 Sep 2022 00:00:00 +0000

On this entry we will cover how to create an new image in Hetzner Public Cloud by using Packer, as result we willl get a snapshot and then we can generate this new instance by using the snapshot created.

Tools used so far:

Ansible
Packer
hcl2_upgrade

I did not create a repo yet because it will be the first part of a personal project I’m working on, hence I will provide a couple of templates below.

S3 by using random provider on Terraform

Sun, 24 Jul 2022 00:00:00 +0000

This is a piece of cake for most of you that are working on tf, I will drop this snippet code where you can create a S3 bucket with an unique name; as you know those requirements should fit in order to create the S3, hence we can use random_string, also we can use random_id, on this case I used random_string.

main.tf

resource "random_string" "randomz" {
  length = 8
  lower  = true
  special = false
  upper = false
}

Above is a resource block where its block label is random_string I defined the block body in that way in order to fit the S3’s requirements.

It has been a while since my last post, I was busy these last couples of weeks; meanwhile I’ve learned how to implement a csi interface on eks (aws k8s) and it’s pretty interesting on AWS by EKS service, thus I though it can be useful this content into a post.

Requirements:

You will need your eks already running.

I’ll point each tools, techs, etc I used on this procedure:

Install Hetzner-CLi on Fedora by Toolbox

On this new entry I will share a briefly installation step by step by using Toolbox at Fedora 34 to use the hcloud-cli. Due we do not have an official package on fedora git-repo yet, hence we can create this container.

Pre-requirement:

Visit Hetzner Cloud Console at https://console.hetzner.cloud, select your project, and create a new API Token.

Let’s start:

1- Create a file named Dockerfile.debian with the following contents(the following image is made to use a script to named and set a token_key):
