## What is Ruby?
A dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.
See: https://www.ruby-lang.org
## How to use this image
### Create a `Dockerfile` in your Ruby app project
```dockerfile
# specify the ruby base image with your desired version ruby:-
FROM ruby:3.2.2-ubi9
# replace this with your application's default port
EXPOSE 8888
```
You can then build and run the Docker image:
```console
$ docker build -t my-ruby-app .
$ docker run -it --rm --name my-running-app my-ruby-app
```
If you prefer Docker Compose:
```yml
version: "2"
services:
ruby:
image: "ruby-ubi:3.2.2-ubi9"
working_dir: /app
expose:
- "8081"
command: "ruby app.rb"
```
You can then run using Docker Compose:
```console
$ docker-compose up -d
```
### Run a single Ruby script
For many simple, single file projects, you may find it inconvenient to write a
complete `Dockerfile`. In such cases, you can run a Ruby script by using the
Ruby Docker image directly:
```console
$ docker run -it --rm --name my-running-script -v "$PWD":/app -w /app ruby-uby:3.2.2-ubi9 ruby your-daemon-or-script.rb
```
## Image Variants
The `ruby-ubi` images come in many flavors, each designed for a specific use case.
All of the images contain pre-installed versions of `ruby`,
[`bundle`](https://bundler.io/). For each
supported architecture, the supported variants are different.
### `ruby-ubi::-ubi9`
This image is based on version 9 of
[UBI](https://www.redhat.com/en/blog/introducing-red-hat-universal-base-image), available in
[the `ubi9` official image](https://hub.docker.com/r/redhat/ubi9).
### `ruby-ubi::-ubi8`
This image is based on version 8 of
[UBI](https://www.redhat.com/en/blog/introducing-red-hat-universal-base-image), available in
[the `ubi8` official image](https://hub.docker.com/r/redhat/ubi8).
