+# Example Application
+
+## TL;DR
+
+```bash
+$ kubectl create -f https://raw.githubusercontent.com/bitnami/bitnami-docker-ruby/master/example/kubernetes.yml
+```
+
+## Introduction
+
+This example demostrates the use of the `bitnami/ruby` image to create a production build of your ruby application.
+
+For demonstration purposes we'll bootstrap a [Rails](http://rubyonrails.org/) application, build a image with the tag `bitnami/ruby-example` and deploy it on a [Kubernetes](https://kubernetes.io) cluster.
+
+## Generate the application
+
+The example application is a [Rails](http://rubyonrails.org/) application bootstrapped using the `rails new` command.
+
+```bash
+$ rails new example --skip-active-record --skip-bundle
+```
+
+## Build and Test
+
+To build a production Docker image of our application we'll use the `bitnami/ruby:2.4-prod` image, which is a production build of the Bitnami Ruby Image optimized for size.
+
+```dockerfile
+FROM bitnami/ruby:2.4 as builder
+ENV RAILS_ENV="production"
+COPY . /app
+WORKDIR /app
+RUN bundle install --no-deployment
+RUN bundle install --deployment
+RUN bin/rails generate controller Welcome index
+RUN bin/bundle exec rake assets:precompile
+
+
+FROM bitnami/ruby:2.4-prod
+ENV RAILS_ENV="production" \
+    SECRET_KEY_BASE="your_production_key" \
+    RAILS_SERVE_STATIC_FILES="yes"
+RUN install_packages libssl1.0.0
+COPY --from=builder /app /app
+WORKDIR /app
+EXPOSE 3000
+CMD ["bin/rails", "server"]
+```
+
+The `Dockerfile` consists of two build stages. The first stage uses the development image, `bitnami/ruby:2.4`, to copy the application source, install the required gems using `bundle install`, generate a dummy controller and precompile the assets. The `RAILS_ENV` environment variable is defined so that `bundle install` only installs the application gems that are required in `production` executions and also for the rails server to start in production mode.
+
+The second stage uses the production image, `bitnami/ruby:2.4-prod`, and copies over the application source and the installed gems from the previous stage. This creates a minimal Docker image that only consists of the application source, gems and the ruby runtime.
+
+To build the Docker image, execute the command:
+
+```bash
+$ docker build -t bitnami/ruby-example:0.0.1 example/
+```
+
+Since the `bitnami/ruby:2.4-prod` image is optimized for production deployments it does not include any packages that would bloat the image.
+
+```console
+$ docker image ls
+REPOSITORY               TAG                 IMAGE ID            CREATED             SIZE
+bitnami/ruby-example     0.0.1               847d58b5bc8a        4 minutes ago       203MB
+```
+
+You can now launch and test the image locally. You will need to access to http://YOUR_IP:3000/welcome/index
+
+```console
+$ docker run -it --rm -p 3000:3000 bitnami/ruby-example:0.0.1
+
+=> Booting Puma
+=> Rails 5.1.4 application starting in production
+=> Run `rails server -h` for more startup options
+Puma starting in single mode...
+* Version 3.10.0 (ruby 2.4.2-p198), codename: Russell's Teapot
+* Min threads: 5, max threads: 5
+* Environment: production
+* Listening on tcp://0.0.0.0:3000
+Use Ctrl-C to stop
+```
+
+Finally, push the image to the Docker registry
+
+```bash
+$ docker push bitnami/ruby-example:0.0.1
+```
+
+## Deployment
+
+The `kubernetes.yml` file from the `example/` folder can be used to deploy our `bitnami/ruby-example:0.0.1` image to a Kubernetes cluster.
+
+Simply download the Kubernetes manifest and create the Kubernetes resources described in the manifest using the command:
+
+```console
+$ kubectl create -f kubernetes.yml
+ingress "example-ingress" created
+service "example-svc" created
+configmap "example-configmap" created
+persistentvolumeclaim "example-data-pvc" created
+deployment "example-deployment" created
+```
+
+From the output of the above command you will notice that we create the following resources:
+
+ - [Ingress](https://kubernetes.io/docs/concepts/services-networking/ingress/)
+ - [Service](https://kubernetes.io/docs/concepts/services-networking/service/)
+ - [Volume](https://kubernetes.io/docs/concepts/storage/volumes/)
+    + [ConfigMap](https://kubernetes.io/docs/concepts/storage/volumes/#projected)
+    + [PersistentVolumeClaim](https://kubernetes.io/docs/concepts/storage/volumes/#persistentvolumeclaim)
+ - [Deployment](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/)
+
+> **Note**
+>
+> Our example application is stateless and does not store any data or does not require any user configurations. As such we do not need to create the `ConfigMap` or `PersistentVolumeClaim` resources. Our `kubernetes.yml` creates these resources strictly to demostrate how they are defined in the manifest.
+
+## Accessing the application
+
+Typically in production you would access the application via a Ingress controller. Our `kubernetes.yml` already defines a `Ingress` resource. Please refer to the [Ingress](https://kubernetes.io/docs/concepts/services-networking/ingress/) documentation to learn how to deploy an ingress controller in your cluster.
+
+> **Hint**
+>
+> https://kubeapps.com/charts/stable/nginx-ingress
+
+The following are alternate ways of accessing the application, typically used during application development and testing.
+
+Since the service `example-svc` is defined to be of type `NodePort`, we can set up port forwarding to access our web application like so:
+
+```bash
+$ kubectl port-forward $(kubectl get pods -l app=example -o jsonpath="{ .items[0].metadata.name }") 3000:3000
+```
+
+The command forwards the local port `3000` to port `3000` of the Pod container. You can access the application by visiting the http://localhost:3000/welcome/index.
+
+> **Note:**
+>
+> If you are using minikube, you can access the application by simply executing the following command:
+>
+> ```bash
+> $ minikube service example-svc
+> ```
+
+## Health Checks
+
+The `kubernetes.yml` manifest defines default probes to check the health of the application. For our application we are simply probing if the application is responsive to queries on the root resource.
+
+You application can define a route, such as the commonly used `/healthz`, that reports the application status and use that route in the health probes.
