# GitOps Repository

This is my GitOps repository for my home cluster. Not included here are the

Ansible playbooks to setup and update all the nodes.

## Setup

Please have a look into the documentation 

## Hardware

I use a cluster of seven Raspberry PIs. Three for the controlplane and the other

four as worker nodes. After some time added two small Lenovo Thinkcentres inspired

by [TinyMiniMicro](https://www.servethehome.com/introducing-project-tinyminimicro-home-lab-revolution/).

You can find more details [here](https://mikevader.github.io/k3s-cluster-infra-apps/).

# copy volume to volume with rsync

rsync -azP source/ destination

-a: archive

include -r (recursive for folders)

and preserves symbolic links, special and device files, modification times, groups, owners and permissions

-z: compression

Useful if used over the network

-P: progress & partial

-nv: dryrun and verbose

trailing slash (`/`) on source is important otherwise itself will be moved as well

## Benchmarks

### Storage

kbench with compare to local-path: https://github.com/yasker/kbench#deploy-comparison-benchmark-in-kubernetes-cluster

### Network

Install iperf with `sudo apt-get install iperf`

Initialize server with `iperf -s` -> listens on port 5001

Start test on client with `iperf -c `

Options:

`-p` to change default port
