truffleruby-community

truffleruby-community is the GraalVM high-performance implementation of the Ruby programming language.

Docker images

See https://github.com/graalvm/container/pkgs/container/truffleruby-community

Supported tags

The no toolchain variants mean the GraalVM LLVM toolchain and its dependencies needed to install C extensions are not included to save space. It is still possible to use gems with C extensions, but the gems must be installed before for instance using a multi-stage build, see Multi-stage build for the no-toolchain images below.

How to use these images

The images are intended for use in the FROM field of a downstream Dockerfile.
For example, specify FROM ghcr.io/graalvm/truffleruby-community:latest or another tag.

Here is an example Dockerfile:

FROM ghcr.io/graalvm/truffleruby-community:latest

# Copy app, Gemfile and Gemfile.lock
COPY . /app
WORKDIR /app

RUN bundle config --local path vendor/bundle
RUN bundle install
RUN bundle exec ruby app.rb

Multi-stage build for the no-toolchain images

# Builder image with the toolchain to install gems
FROM ghcr.io/graalvm/truffleruby-community:latest AS builder

# Copy app, Gemfile and Gemfile.lock
COPY . /app
WORKDIR /app

RUN bundle config --local path vendor/bundle
RUN bundle install

# Resulting image without the toolchain and including the gems
FROM ghcr.io/graalvm/truffleruby-community:ol9-slim

COPY --from=builder /app /app
WORKDIR /app

RUN bundle exec ruby app.rb

Installing system packages

Oracle Linux 8 and 9

Use microdnf install some-package.

Debian

Use apt update and apt install some-package.

Manually Building the images

For manually building a truffleruby-community image from one of these Dockerfiles, use:

docker build --build-arg GRAALVM_VERSION=<GraalVM Version> -t ghcr.io/graalvm/truffleruby-community:TAG -f Dockerfile .
