Been keeping my eye out for something like this. I have wanted to build a cheap bare metal k8s cluster for my homelab. While ARM is nice, most containers are targeted at x86.
- heyoni 7y agoIs there ever a time when a container can’t be rebuilt for arm? Seriously asking
- viraptor 7y agoRebuilt - sure, most of the time. But unless you want to spend lots of time rebuilding containers, you may want Intel instead. If you have a "real" machine with ARM available you can build larger software quickly, but if you don't, building something on rpi can take tens of minutes easily.
- rmoriz 7y agoYou can crosscompile images for ARM on x86 using qemu, even docker hub inofficially supports it.
- milofeynman 7y agoThis was my exact thinking. I wanted a pi cluster but didn't want to deal with arm. Exciting...
- rbanffy 7y agoYou can also get a bunch of thin clients on eBay and use those. The AMD APU based ones even have GPUs you can play with.
- larrywright 7y agoDo you have a model number or something that I can use to search for?
- oomkiller 7y agoJust saw this yesterday, shame they're sold out but I think this is what they're referencing: https://computers.woot.com/offers/hp-t620-amd-flexible-thin-client-1?ref=w_cnt_wp_0_87 https://computers.woot.com/offers/hp-t620-amd-flexible-thin-...
- larrywright 7y agoThat’s helpful actually. There are plenty on Ebay, which is fine for just playing around with.
- vardump 7y agoJust out of curiosity, what kind of issues you have with ARM? Edit: Do you refer to this? https://blog.cloudkernels.net/posts/rpi4-64bit-virt/ https://blog.cloudkernels.net/posts/rpi4-64bit-virt/ Still at least some DMA issues: https://github.com/raspberrypi/linux/issues https://github.com/raspberrypi/linux/issues
- pizza234 7y agoIt depends on how much you want to spend. The ODROID H2 is finally available (it hasn't been available for a long time, due to Intel not producing enough chips (or not selling them to ODROID and others, not sure)), and you can consider it a high-end SBC or a low-end NUC. The price for board+4GB RAM is roughly 150$ vs 80$ for the RPi 4¹. It's the lowest priced x86 system available², and the performance is significantly superior to ARM boards (in the range 2-4x of RPi 4). ¹=very rough prices; it's hard find the lowest prices, and it's not clear if it makes sense to do so ²=please no comparisons with discontinued machines (there's always somebody popping up with such comparisons...)
- atomi 7y agoThe RPi 4 w/ 4gb ram is $55 at my local Microcenter - and an extra $10 for the power supply.
- mey 7y agoWas aiming to get the system together for $500 or less, including power supplies for a five node system. So SBC/NUC systems above $100 made it less compelling. Obviously performance isn't the consideration here, but number of physical nodes.
