Missing aarch64-linux platform gem for Docker ARM64 builds

[marcinwolskitds]

Platform detection mismatch for aarch64-linux in Docker builds

Problem

When building a Docker image for ARM64/aarch64 architecture, the sqlite-vec gem cannot be resolved by bundler due to a platform naming mismatch. The gem provides arm64-linux platform binaries, but Ruby/Bundler in Docker Linux containers detects the platform as aarch64-linux, causing bundler to fail to find a matching gem.

Environment

• OS: Docker on Linux ARM64 (aarch64)
• Ruby version: 3.4.0
• Bundler version: 2.6.9
• sqlite-vec version: 0.1.7-alpha.2
• Base Docker image: Custom Passenger image (Ruby 3.4.0 on Debian-based Linux)
• Architecture: linux/arm64 (aarch64)

Steps to Reproduce

1. Create a Gemfile with:

gem "sqlite-vec", ">= 0.1.7.alpha.2"

2. Create a Dockerfile for ARM64:

FROM phusion/passenger-ruby34
RUN gem install bundler -v 2.6.9
COPY Gemfile Gemfile.lock ./
RUN bundle install

3. Build for ARM64 platform:

docker build -t test .

Error Output

Could not find gems matching 'sqlite-vec (>= 0.1.7.alpha.2)' valid for all
resolution platforms (arm64-darwin, arm64-linux, aarch64-linux) in rubygems
repository https://rubygems.org/ or installed locally.

The source contains the following gems matching 'sqlite-vec (>= 0.1.7.alpha.2)':
  * sqlite-vec-0.1.7.alpha.2-arm64-darwin
  * sqlite-vec-0.1.7.alpha.2-arm64-linux
  * sqlite-vec-0.1.7.alpha.2-x86_64-darwin
  * sqlite-vec-0.1.7.alpha.2-x86_64-linux
  * sqlite-vec-0.1.7.alpha.2-x86_64-mingw32

Analysis

When running in Docker on ARM64:

• ruby -e "puts Gem::Platform.local" returns: aarch64-linux
• Available gem platforms include: arm64-linux (not aarch64-linux)
• Bundler tries to match aarch64-linux but can't find it
