Exampleapp in Ruby

Local Development

This application is built to run in a cluster and not locally. It would take some additional changes to have it work locally.

$ bundle install
$ rackup

Create the Docker image.

$ docker build . -t exampleapp-ruby

Test the Docker image.

$ docker run -it -p 8080:8080 exampleapp-ruby:k8s

Push the Docker image.

$ docker push USERNAME/exampleapp-ruby:k8s

The assumption is Kubernetes, Vault, and Consul are configured correctly.

Update the configuration file to use your Docker image.

Apply the configuration that describes the exampleapp-simple pod.

$ kubectl apply -f exampleapp.yaml

Check the logs of the server.

$ kubectl logs exampleapp-simple-c54944b4c-pjqlc

$ kubectl exec -it exampleapp-simple-c54944b4c-pjqlc /bin/bash
