metallb VS speedtest

Hey guys, I want to share a guide I’m pretty proud of which is talking about setting up kubernetes which leverages https://kubespray.io/#/ and https://metallb.universe.tf/ so you can host this yourself most people when spinning up kubernetes opt for k3s or get stuck with all the options or unable to setup the external ips for their services so these tools will eliminate the problem.

Have a closer look at MetallLB.

To avoid that, you can use a combination of haproxy and keepalived, an enterprise grade load balancer like the one from F5 or Citrix. Besides that you can also work with https://kube-vip.io or https://metallb.universe.tf.

Not sure if klipper is usable in a cluster with multiple nodes, as it binds to one port only. You may want to use MetalLB instead: https://metallb.universe.tf/

Then deploy MetalLB https://metallb.universe.tf/

What issue do you see with the load balancer? For self hosted clusters, one can use MetalLB for example to have such single outfacing IP which will failover to another node keeping the same IP if a node dies.

Quoting from their docs:

metalLB to manage bare-metal LoadBalancer services - WIP - Only L2 configuration can be set-up via playbook.

I recently installed OpenWRT on a TP-Link TL-WDR4300, and put the router of my ISP in bridge mode. Now I noticed that the wireless speeds are significantly slower (40mbps vs 3mbps via librespeed.org), after using OpenWRT.

Try hosting a DIY speed test on a cloud server (like Google colab or the free oracle instances or whatever):

https://github.com/librespeed/speedtest

here's the top two results if you search for "open speed test nginx reverse proxy": https://github.com/librespeed/speedtest/wiki/Reverse-proxy-with-Nginx https://github.com/henrywhitaker3/Speedtest-Tracker/issues/924

Or https://librespeed.org/

Fast.com is giving me ~ 250Mbps https://librespeed.org is giving me ~ 112Mbps the one constant between all the tests seems to be the 52Mb upload

It should be DIA. They provide the internet connection to the company since 2 decades and it's a very small ISP, so it's very vague in terms of contract. Iperf was giving me very terrible results with TCP, UDP was giving me a couple of Gbit/s throughput, definitely a wrong result. We are using this self hosted speedtest. All my results above are based on this software: https://github.com/librespeed/speedtest

Put a copy of Librespeed on a web server that's accessible through the VPN and told them to use that. For (our) convenience, it's logged into a database that's correlated with the VPN login/logout times so the users don't even need to log in to use it, but we still know whose test result it is.
