raspberry-pi-dramble VS ddclient

https://www.pidramble.com - but you do need to power the router. 5th port is an uplink

Don't bother. Just put them on an open stack and blow a quiet Noctua fan sideways through the stack. I used to have a four-pi4 cluster ala https://www.pidramble.com and one fan blowing back to front was easily good enough. I also removed the fans from the official PoE HATs since they sounded like rocket engines no matter what I did.

There's no rack, it's simply on the corner of my desk. I haven't made photos of it but it looks pretty much like Jeff Geerling's Dramble: https://www.pidramble.com/

Had a pi 'dramble' just like this one and it worked fine. I ran k3s at the time on it. Since it was a lab experimentation thing, I didn't throw more hardware at it, but I could have likely gotten similar results with a bunch of Vagrant/VirtualBox VMs on one NUC.

Automate the Pi Dramble website I run in my basement with Drupal Pi.

How is latency and stuff? Any slowness that you wouldn't expect from the software that may come from running it on a rpi4? I've been thinking of setting up a few services, but I kinda want to do something like the Pi Dramble, wasn't even aware that a single pi would have the power to run all of these services. Though I'm not actually surprised it does.

A couple years ago when I thought I'd have to get into kubernetes for a living, I built a 4x4GB pi4 cluster with the exact parts list from Jeff Geerling's "dramble" setup (link) and did a bunch of experimentation with k3s as a lightweight cluster solution. Worked pretty amazingly for things like "spin me up 10 more of those things" and for moving things around to upgrade the SD card on the 3rd pi while keeping the services running on the other pi. But I don't need to do kubernetes for a living so the cluster is just sitting here collecting dust powered-down basically.

I see this kind of question asked a lot when people are posting their Kubernetes Pi clusters. The rpi 4 quad core with 4-8GB RAM gives a lot of potential for the price in a kuberenetes setup I feel. I found the pi dramble project interesting, and even more the turing pi using rpi compute modules. Are NUCs really a cheaper alternative for a kubernetes cluster, every time I start try to come up with something I end up with a far more expensive setup and fewer cores. Any hints on viable setups, e.g. replacing 4x POE powered RPI 4's.?

My setup is exactly the same as the top photo on https://www.pidramble.com just with the stack'o'pi zip-tied to the switch so I can move it around without the things sliding around.

You can find an example of the full config file here: https://github.com/ddclient/ddclient/blob/master/ddclient.conf.in

Check your distribution's repos first, but Ddclient doesn’t have an automatic installation procedure. Get the tar-file from https://github.com/ddclient/ddclient/releases and untar it. Copy the perl script to your favorite location (ex. /usr/sbin) and create a

ddclient has support for Google DNS. It is available as a package on Ubuntu/Debian.

As I recall ddclient is a perl script or some such. It should be relatively easy to just download and build it. https://github.com/ddclient/ddclient/releases

Which version of OPNSense are you running at the moment? There were changes to the os-ddclient package in the 23.1.6 patch in order to fix the config generation in response to changes in ddclient 3.10.0 when enabling IPv6 updates (ipv6=yes was disabled, and replaced with usev4/usev6. If a reboot doesn't help, I'd be happy to give you a hand with debugging the ddclient config.

So a came accros Inadyn which compared to the current state of DDclient, is being actively maintained. More info here from what i am talking about.

You can use ddclient, it supports a lot of DNS providers: https://github.com/ddclient/ddclient
