Unable to use Multi-Region access point on a rails project

[sastromskis]

Describe the bug

Accessing multi-region access point requires the aws-crt gem. After looking through available resources online i found that a similar problem was reported earlier:
#2630

However, following the instructions in the thread did not solve the problem. Those match with the official docs:
https://github.com/awslabs/aws-crt-ruby

running a rails console crashes with the following error:
locally on an M1 mac: Could not open library 'libaws-crt-ffi.dylib'
docker on ruby:2.7.2-alpine: Could not open library 'libaws-crt-ffi.so': Error loading shared library libaws-crt-ffi.so: No such file or directory

Expected Behavior

I'd expect that adding these gems to a Gemfile

gem 'aws-sdk-s3'
gem 'aws-sigv4', '1.4.1.crt'

would allow to use Multi-Region access points via Aws::S3::Client

Current Behavior

Thanks for opening an issue. It looks like it's an issue with compatibility - alpine I don't think is supported by CRT yet. Potential related issue - awslabs/aws-crt-ruby#43. Could you please add details or a new issue in aws-crt-ruby instead?

If you try a different architecture, try installing the latest aws-crt gem and the latest aws-sigv4 gem - do not use the CRT version of aws-sigv4 (developer preview version only - it's been merged into the latest aws-sigv4)
