Cannot create workspace with GitLab deployed on RHEL 8.x with x86_64 arch: cannot execute binary file

Summary

Cannot create workspace with GitLab deployed on RHEL 8.x with x86_64 arch. Creation fails with cannot execute binary file error.

Steps to reproduce

  • Deploy a GitLab instance on a server with x64_64 arch - I've used RHEl 8.10 and GitLab 17.9.1.
  • Configure workspaces by following our docs.
  • Try to create a workspaces in one of the projects from the page https://GITLAB_URL/-/remote_development/workspaces/new

What is the current bug behavior?

Creation fails with the error:

Workspace create devfile flatten failed: /opt/gitlab/embedded/lib/ruby/gems/3.2.0/gems/devfile-0.1.1/bin/devfile: 
/opt/gitlab/embedded/lib/ruby/gems/3.2.0/gems/devfile-0.1.1/bin/devfile: cannot execute binary file

What is the expected correct behavior?

Workspace should be created successfully.

Relevant logs and/or screenshots

There's an error in puma logs pointing to the fact the binary does not have a correct architecture:

==> /var/log/gitlab/puma/puma_stderr.log <==
devfile-gem only supports os: darwin and architecture: arm64 for 'ruby' platform

Additional information

The devfile binary has incorrect architecture indeed. Trying to run it directly also results in the same error:

/opt/gitlab/embedded/lib/ruby/gems/3.2.0/gems/devfile-0.1.1/bin/devfile: cannot execute binary file: Exec format error
file /opt/gitlab/embedded/lib/ruby/gems/3.2.0/gems/devfile-0.1.1/bin/devfile
/opt/gitlab/embedded/lib/ruby/gems/3.2.0/gems/devfile-0.1.1/bin/devfile: Mach-O 64-bit arm64 executable, flags:<|DYLDLINK|PIE>

Workaround

Build the binary manually from the project https://gitlab.com/gitlab-org/ruby/gems/devfile-gem/ or replace it with the binary obtained from a working server (I took one from Deb-based GitLab instance 17.9.1 where workspaces feature worked for me).
