Kubernetes and Helm (Part-2)
In previous article we saw the helm architecture, components and installation in kubernetes cluster with example .

In this post we’ll see another example of helm.
In last post we installed kubernetes dashboard using helm. so now we we’ll run apache server using helm.
To run httpd using helm charts, firstly we’ll search apache charts:
$ helm search bitnami/apache
It will show you all the possible outputs.
now we have to install that helm chart , so for that we will use:
$ helm install bitnami/apache — name httpd
when you hit the above command then you’ll see the namespace and state of pod as a output . it will also show the deployment, pod and service information .
here you don’t need to create service manually as we do in kubernetes . when you install helm chart that time it will automatically create service for this application.
To check the service of newly created pod use:
$ kubectl get svc
In above output you’ll see external Ip is in pending state due to Load Balancer type. so to assign external ip you have to edit service
$ kubectl edit svc apache
For assign externalIP, use ip of your master node in yaml file of svc. so after that external ip will be assign to your application
By using public ip of your node instance you can curl this website.
To check running application using helm:
$ helm list
To remove the application we can use:
$ helm rm apache
In this way we conclude helm with apache example. you can also search for other helm charts and explore .
