I ran lots of containers on a Pi 4 but recently purchased two cheap Chinese mini PC's with 16GB RAM and an SSD. They're so much faster and only a bit dearer than a Pi. I run Proxmox on both.
Absolutely nothing wrong with the Pi though. The Pi 4 lives on with a USB drive attached. I have NFS configured on it to backup my Proxmox VMs to it. It also hosts all the media for Jellyfin.
If you think about it, the kubernetes nodes often are only raspberry pis specwise. 2-4 cores, 8-16gb of ram
I have been in for a couple months now, Proxmox cluster with two machines.
Works out nicely as I crash the first one too often and the DHCP going down was unacceptable, wish I got a slightly better cpu for the minipc but meh, maybe I can upgrade it later.
To be fair, also love the mini pc's and having a larger NAS. For me the PoE capabilities of the Pi's are definitely the reason I use them
The HAT-ability of RPi makes them enough for me. You can add sata ports, PCIe, and more with a simple HAT.
any recommendations on hats for sata?
Been running one from Radxa for a while. Just make sure to check the power requirements of your drives.
a pie is neat. thats it. does it have enough ram for hosting & running all your containers? no.
I think any mini-pc/old laptop is better, and probably cheaper than a raspberry pi nowadays
I would have disagreed with you when Pis were like $50 and chaining 3 Pis together with a hard drive was a fun project to do self hosting.
Now to get to the beefiest raspberry pi, it's $120. And in the range, yeah, for price and reliability, use a mini-pc/laptop.
Yeah honestly i can't get anything done with a raspberry. Maybe i host too many services ?
Nah, they are underpowered for their current price. When you could get your hand on a raspberry pi 3 for 35β¬ 10 years ago it was a bargain. But now it's not the case.
Honestly Raspberry Pis are pretty underpowered as hosts for more than a handful of super basic services, and given they consume 20-30w at minimum you're easily getting into used office desktop territory where you can get a ton more performance right out of the gate.
The real value in the raspberry pi is in the GPIO and the cohesive ecosystem of accessories to plug into said GPIO. You can do so many cool automations and controls using just an RPi (especially if combined with something that can't be accomplished more cheaply and easily with an ESP32) but as a server host they're pretty crap in comparison to a decade old business PC off of eBay
I've got 3x RPi 4/5 with external drives and other USB running ~10 containers at 4-6W each. How did you make them draw 20W?
I've found that a pi is good enough, computationally, but not reliability wise.
A lot of things like advanced light control goes through my host, so any lockups or crashes are bad. My pi held up for about 18 months before it began to play up. I've found a small NUC system has higher reliability for the same price and power usage.
Yes, you can optimize a lot. Especially with Linux. I did the same and even started to replace program that did too much, bloated, with my own programs. To speed up the development I did it with AI and Cursor.
So close. Started on raspberry pi. Went for a cluster with dpckrt swarm. Finished with a nas and a 10years old game computer as a mediacenter. (That the electricity bill whoch made me stop the cluster)
I need a kubernetes cluster with high availability, load balancing and horizontal pod autoscaling, because that is something I want to learn. I don't care that it's just for wife's home-made dog collars webshop.
Yeah that's basically it for me. I have a collection of dev boards, old hardware and stuff other people were tossing out set up for a variety of purposes (Kubernetes clusters, two build farms, network boot, etc.). None of it is because I feel I "need" any of that for self hosting. In practice two old desktops with a bunch of drives would be perfectly capable of providing everything I need including redundancy. I have all that stuff because I'm learning and experimenting.
The only problem I've had with Raspberry Pi is that some apps want to write a lot of stuff to "disk", and the default "disk" on a Pi is a MicroSD card which dies if you keep writing things to it. Sure, you can always plug something into a USB slot, but that adds a bit of friction to the whole process.
Oh, also, I wish it were easy to power a whole bunch of Pi units. Each one needing its own wall wart is a bit annoying, and I've had iffy results using weaker, less steady power supplies with multiple ports intended for things like phones.
I ended up just buying an industrial mSD card. Has yet to fail.
I really recommend a HAT with SSD, totally worth the investment.
Yeah, but then you have to get a kind of case that can handle a Pi plus that hat. It's a good idea, it's just a bit more fiddly than just the typical booting from the SD card and doing everything that way.
Switched from a raspberry pi 3 to a second hand x86 thin client (lenovo thinkcentre m920q) because raspberry pi 4 were not available at the time. Made me learn proxmox and a bunch of other cool stuff my raspi couldn't handle.
I'm rooting for ARM / RISC-V to become more popular in desktop computing / servers though.
i think the best choice is a cheap used pc or laptop, or server. Reduces electric waste. I also host my own server on a 19 year old Dell Insprion 1300
