Error when trying to build an image for ruby 2.5.9 with an arm64 arch

[alexandrebryszkowski]

Hello,

I've got a problem when trying to build an image for ruby 2.5.9 with an arm64 arch with the focal version of Ubuntu.

I need a docker image for ruby 2.5.9 with a arm64 architecture working on a M1 processor from Apple (on macOS 12.1), but I've got this error:

rake --trace docker:build arch=arm64 ruby_version=2.5.9 ubuntu_version=focal

Am I missing something ?

Thank you

Try and comment this line: https://github.com/ruby/ruby-docker-images/blob/master/Rakefile#L133

I believe it's to run docker through qemu as arm64 when your cpu is not an M1, and since you are using M1 you don't need that.

Hello,

Thank you for your response.
It works but it seems bundle was not present:

So I commented 'bundle --version' here : https://github.com/ruby/ruby-docker-images/blob/master/install_ruby.sh#L94

And now it works :

Use 'docker scan' to run Snyk tests against images to find vulnerabilities and learn how to fix them

Thank you for your help!

For anyone reading this, Bundler is part of Ruby since version 2.6 while we are trying to build the image for Ruby 2.5.
