+[![Build status](https://badge.buildkite.com/aab023f2f33ab06766ed6236bc40caf0df1d9448e4f590d0ee.svg?branch=main)](https://buildkite.com/buildkite/ruby-docker-example/builds/latest?branch=main)

+
+This repository is an example [Buildkite](https://buildkite.com/) pipeline that demonstrates how to test a [Ruby](https://www.ruby-lang.org/en/) project using [Docker](https://docker.com/).
+
+👉 **See this example in action:** [buildkite/ruby-docker-example](https://buildkite.com/buildkite/ruby-docker-example/builds/latest?branch=main)
+
+See the full [Getting Started Guide](https://buildkite.com/docs/guides/getting-started) for step-by-step instructions on how to get this running, or try it yourself:

+
+## How it works
+
+This example:
+- Uses the [Ruby Docker image](https://hub.docker.com/_/ruby/)
+- Defines a [Docker Compose](https://docs.docker.com/compose/) service to run tests
+- Uses a simple RSpec test suite for demonstration
+
+Key files:
+- [`Dockerfile`](Dockerfile) – defines the Ruby environment
+- [`docker-compose.yml`](docker-compose.yml) – defines the app service
+- [`pipeline.yml`](.buildkite/pipeline.yml) – uploads the pipeline
