ARM VM support: cpu_arch in fly.toml?

[paj]

Now that Firecracker has ARM support GA, any plans to offer ARM VMs on Fly? We build on ARM CI runners and currently have to cross-compile to x64 just for deployment. Would be great to have something like:

[[vm]]
cpu_kind = “shared”
cpu_arch = “arm64”
cpus = 1
memory = “512mb”

Would simplify the build pipeline a lot. Plus ARM tends to be more efficient (in certain instances)

Anyone else want this?

ARM-based machines

We think about it quite a lot! It’s going to take years, though. The two biggest consumers of ARM built their own chipsets. As a result, the market for independent ARM chips is not very healthy. Last time we tried to order ARM servers the manufacturer went out of business before they shipped them. Do you want ARM for more reasons than just cost savings?

Makes sense, not mission critical for us just something that popped up. I saw those old threads from 2022, just wanted to see if there were any updates.

Thanks!
