Ruby

Installs Ruby and a version manager (mise or rbenv) along with the dependencies needed to build Ruby.

Example Usage

Using mise (default)

"features": {
    "ghcr.io/rails/devcontainer/features/ruby:1": {
        "version": "3.3.0"
    }
}

Using rbenv

"features": {
    "ghcr.io/rails/devcontainer/features/ruby:1": {
        "version": "3.3.0",
        "versionManager": "rbenv"
    }
}

Using mise explicitly

"features": {
    "ghcr.io/rails/devcontainer/features/ruby:1": {
        "version": "3.3.0",
        "versionManager": "mise"
    }
}

Opting in to precompiled Rubies with mise

"features": {
    "ghcr.io/rails/devcontainer/features/ruby:1": {
        "version": "3.3.0",
        "versionManager": "mise",
        "usePrecompiledRubies": true
    }
}

When using mise, this feature keeps ruby.compile=true by default so Ruby is compiled from source. Set usePrecompiledRubies to true to make mise prefer precompiled Rubies when they are available.
