How to Deploy Application In Kubernetes (Local Environment)

 

 

Introduction:

As the demand for scalable and containerized web applications grows, Kubernetes remains a popular choice for orchestrating and deploying containerized workloads. In this guide, we'll walk you through the process of deploying an Angular application on Kubernetes using NodePort, providing a straightforward method to expose your application to the external world.

Prerequisites:

Ensure you have the following prerequisites in place before starting the deployment process:

1. A functioning Kubernetes cluster- Tutorial to Install Kubernetes Locally
   
2. Installed kubectl command-line tool
3. Docker installed to containerize your Angular application.

Step 1: Clone The Repo

git clone https://github.com/shawon100/Angular-CRUD

Step 2: Apply the manifests file

Then Go to manifests folder 

At first deploy the deployment.yml file 

 

apiVersion: apps/v1

kind: Deployment

metadata:

name: webclient-angular-crud

spec:

selector:

matchLabels:

app: webclient-angular-crud

replicas: 1

template:

metadata:

labels:

app: webclient-angular-crud

spec:

containers:

- name: webclient-angular-crud

image: shawon10/webclient-angular-crud:85

imagePullPolicy: Always

ports:

- containerPort: 80

 

kubectl apply -f deployment.yml

 

Then deploy the service.yml

apiVersion: v1

kind: Service

metadata:

name: webclient-angular-crud-service

spec:

selector:

app: webclient-angular-crud

ports:

- protocol: "TCP"

port: 80

type: NodePort

kubectl apply -f service.yml

Step 3: Check the Pods, Services, and Ip address

Check the pod

kubectl get po

Check the Service

kubectl get svc

Note down the NodePort

Check the Ip of Node

kubectl get nodes -o wide

 

Step 4: Access Your Angular Application:

Once the service is created, access your Angular application using the NodePort on any of your cluster's nodes. Find the node's external IP and access the application at 

http://<node-ip>:NodePort
