Hello World Helm Chart

This is a basic demonstration Helm chart but can double up as a chart to server basic web pages from any docker container.

Pre Requisites:

• Kubernetes 1.16 with nginx ingress enabled:

• https://kubernetes.github.io/ingress-nginx/deploy/

• Helm 2.15.1

Installing the Chart

To install the chart with the release name helloworld in the default namespace:

$ git clone https://github.com/nabbott2008/helloworld.git
$ helm install --name helloworld helloworld

Parameter	Description	Default
image.repository	Image repository	never152/helloworld
image.tag	Image tag	develop
image.pullPolicy	Image pull policy	IfNotPresent
replicaCount	Number of replicas to run	3
ingress.host	Ingress host header	test.com
service.port	Port service is listening on	80
target.port	Port container is listening on	5000

Testing on Minikube

If you have installed the chart in Minikube, and used default values, you can test with this curl from the host machine:

$ curl -H "Host: test.com" $(minikube ip)

Using as template web service chart

The values above allow you to use this Helm chart as a basic web service chart.

You can use any docker image you require as long as it's serving HTTP requests.

Ensure you change the port ports appropriately depending on what port your docker container listens on.
