ARM64 support?

[lemniskett]

Hi, I'd like to deploy this in my Pi cluster, I build the fx from source and ran the example js function, but then i encountered this error:

root@functions:~/fx/examples/functions/JavaScript# fx up --name hello func.js 
Starting building
100 / 100 [----------------------------------------------------------------------------------->] 100.00% 1 p/s100
Starting deploying hello
93 / 100 [------------------------------------------------------------------------------->_____] 93.00% 21 p/s
deploying hello: ✗
*****************
container start failure: <exec /usr/local/bin/docker-entrypoint.sh: exec format error

It seems like it produced an x86_64 image during build?

Hi, @lemniskett
Thank you raising this, I did not test on Pi before, I may not be able to do it very soon, if you want, you can create a MR, thanks a lot.
