How to Deploy application in k8s using Helm

Create Dockerfile for your application .. I am creating for tomcat application..

Edite Chart.yaml , deployment.yaml, service.yaml, values.yaml file as per your project requirement.

Chart.yaml

#values.yaml

image:

repository: kishordhangar/tomcat

pullPolicy: IfNotPresent

# Overrides the image tag whose default is the chart appVersion.
  tag: "9.0.20"

service:
  type: NodePort
  port: 8029
  targetport: 8080

You can Build Your docker image.. navigate your dockerfile dir and run command

$ docker build -t dockerhub_repository/tomat:9.0.20 .

Push docker image to dockerhub

$ doker login

$ docker push dockerhub_repository/tomcat:9.0.20

Edite service.yaml file

navigate project dir and run

$ helm repo index .

To check any errors run command

$ helm lint
$ helm lint

==> Linting .

[INFO] Chart.yaml: icon is recommended

1 chart(s) linted, 0 chart(s) failed

that means everything are correct

Push edited files to your github repository

after commited successfully then try to install the chart

first create your own namespace

$ kubectl create ns helmproject3
$ helm install helmrelease2 helmproject3 -n helmproject3
$ helm list

$ helm list -A
$ kubectl get pod

$ kubectl get pod -A

$ kubectl get svc

$ kubectl get svc -A
$ minikube service helmrelease2-helmproject3

$ minikube service helmrelease2-helmproject3 -n helmproject3 --url
