[grpc-io] Re: Kubernetes, NodeJS and gRPC

['Richard Belleville' via grpc.io]

Can you please provide more context? Your headless service should create a 
DNS entry in kubedns as you've described and the kubernetes NodeJS client 
should be able to resolve that DNS entry. Exactly what is the issue you are 
experiencing?

[grpc-io] Re: gRPC python socket_mutator

['Richard Belleville' via grpc.io]

As I said, you're going very far off-road here. I don't think anyone has 
ever tried this before.

[grpc-io] Re: raspberry pi zero

['Richard Belleville' via grpc.io]

I think what's happening here is the installing is falling back to a 
from-source build because PyPi doesn't have precompiled artifacts for your 
architecture. The compilation process is taking too much memory for your 
machine and the compiler process gets OOM killed with SIGKILL.

Exactly which architecture you have depends on the model of your RasPi 
Zero. An RPi Zero W is ARMv6Z and an RPi Zero 2 W would be ARMv8. 
Regardless, piwheels  should be able to provide 
precompiled artifacts for you.

[grpc-io] raspberry pi zero

[Neil Butler]

Hi,

I am trying to install firebase-admin on a raspberry pi zero and when it
comes to installing grpcio the installation is killed:
[image: image.png]

I have tried using Thonny also and i get "process returned with code -9"

are you aware if this is a known thing with raspberry pi zero/raspberry pi
OS?

do you have any idea how I can get it installed?


thanks,

n
