• #6614 has broken docker image push
• builds are stuck on "building wheel for grpcio"
• Related issue: #6291

Edit: Docker push is not broken, but it does take a significant amount of time just to build this one package

After much research, this seems to be related specifically to building the alpine image on ARM.

The downloads page shows lots of other precompiled wheel options but not the ones we want.

Potential Solutions

A) Use pre-build grpcio library

Alpine ships the py3-grpcio package which comes with the 1.54.2 version of the library pre-installed. This may sidestep our need to build the library entirely.

B) Different Base Image

Alpine / musl is a big part of the "problem" here - using a different base image would make this a much more tractable problem.

C) Compile Wheel

Can we compile a wheel for grpcio ourselves for the aarch64 architecture?

D) Consider Default Support for grpcio

Currently we use this for tracing. I do not want to split up dependencies, this is not my ideal solution. But including it here as a point of consideration.
