Unable to run an app on kubernetes

[denismakogon]

Steps to reproduce:

1. Create and publish the container to the registry.
2. Create a deployment:

kubectl run viz-ui --image=<whoami>/vizceral-example:latest --replicas=1 --port=8080
kubectl expose deployment viz-ui --port=8080 --type=LoadBalancer

curl -v http://192.168.99.100:<exposed-port>
*   Trying 192.168.99.100...
* TCP_NODELAY set
* Connected to 192.168.99.100 (192.168.99.100) port 31865 (#0)

Im also having trouble getting to run

$ docker run -d -p 41911:8080 --name test-${CI_JOB_ID} -e America/New_York ${DOCKER_TEST_IMAGE}
5c55d19e734bef42eb07a23338dea94b27f62044e30bb50728068672a74a4206
$ echo "Sleeping for 60" && sleep 60
Sleeping for 60
$ export RESPONSE=$(curl --write-out %{http_code} --silent --output /dev/null localhost:41911)
$ echo "Response was $RESPONSE"
Response was 000

EDIT:

My error is also Invalid Host header

Is this because of the build warnings?

@denismakogon I was finally able to figure this out.

This app relies on https://github.com/webpack/webpack-dev-server. This allows you to run a local development server that will autoupdate as the files change live on the disk. By default this server only allows connections from localmachines. You can fix this several ways, they all are based on configuring a devServer block in your webpack.config.js.

module.exports = {
  devServer: {
  },

You can then set disableHostCheck: true to allow all connections or you can set one or more URL's you will allow access to with the allowsHosts option. More details can be found here https://webpack.js.org/configuration/dev-server/

I have not yet figured out how to run this in non dev move, but I'm far from that stage anyways.
