How to deploy Ember app to kubernetes

As part of my unfinished project observerio I were working on my first ember dashboard and when I finished to work on prototype, decided to deploy it as pod in kubernetes cluster in digitalocean. Why kubernetes probably it's saving a lot of time if you are solo developer and don't have enough money to support the non profitable idea.

On the first deploy I found that it was pretty easy to build released version of ember app but on open the dashboard in browser I found that my routing is not working properly. After googling the solution someone suggested to change nginx settings on serve ember app.

Docker.released used by pod:

FROM alpine:3.6

COPY dist/ /app

WORKDIR /app

CMD ["tail", "-f", "/dev/null"]

How to change nginx settings? I started to think about it. I didn't know internal stuff in k8s and the next step for me was to explore a bit the containers from running processes in kubernetes cluster. In ingress pod I found the nginx template that used on serving my ember pod.

nginx.tmpl

To make sure that I would have the same template as installed ingress container, I copied nginx.tmpl from the container and placed there(line: 458):

{{ if and (eq $path "/") (eq $server.Hostname "observer.rubyforce.co") }}
            try_files $uri $uri/ /index.html?/$request_uri;
{{ end }}

Then changed ingress controller to use the new template via config map, example of Deployment

Probably it could be helpful for someone as well.
