joenyland/ruby-alpine-libv8 repository overview

⁠docker-ruby-alpine-libv8

This image is based on the official Ruby image⁠ for Alpine Linux. It contains the libv8⁠ gem installed with a V8 engine that's built against the musl C library⁠ that Alpine Linux uses.

One can, of course, just install NodeJS in Alpine Linux and ExecJS will just use that⁠. If you'd prefer not to use NodeJS, then you can use this image to base your app on.

⁠Example

Here's what happens with the normal Alpine based Ruby image:

docker run -it --rm ruby:alpine sh
apk add build-base
gem install therubyracer
irb(main):001:0> require 'v8'
LoadError: Error relocating /usr/local/bundle/gems/therubyracer-0.12.3/lib/v8/init.so: __vfprintf_chk: symbol not found - /usr/local/bundle/gems/therubyracer-0.12.3/lib/v8/init.so

And here's it working with this image:

docker run -it --rm joenyland/ruby-alpine-libv8
apk add build-base
gem install therubyracer
irb(main):001:0> require 'v8'
=> true
irb(main):002:0> V8::Context.new.eval 5 * 9
=> 45
