The above example `Dockerfile` expects a `Gemfile.lock` in your app directory. This `docker run` will help you generate one. Run it in the root of your app, next to the `Gemfile`:

|
```console
|
|
|
-$ docker run --rm -v "$PWD":/usr/src/app -w /usr/src/app ruby:2.5 bundle install

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":/usr/src/myapp -w /usr/src/myapp ruby:2.5 ruby your-daemon-or-script.rb
|

+$ docker run -it --rm --name my-running-script -v "$PWD":/usr/src/myapp -w /usr/src/myapp ruby:3.0 ruby your-daemon-or-script.rb
