Jenkins – Docker Image + Docker Hub + AKS (Azure Kubernetes Service)
1. Install below Plugins
-
Docker
-
Docker pipeline
-
Kubernetes Deploy plug-ins
2. Update Docker Hub credentials in Jenkins > Manage Credentials
3. Update AKS Credentials in Jenkins
Go to C:\Users\<USER_NAME>\.kube\config & Copy complete file content starting
from apiVersion: v1
Go to Manage Credentials > Add Credentials, In content – paste copied content
from config file. 
4. Create Jenkins Pipeline
Create new Jenkins Item > Type as Pipeline
Update Pipeline Code : Jenkinsfile
pipeline {
agent
environment {
//once you sign up for Docker hub, use that user_id here
registry = "smlcodes/docker-employeeservices"
//- update your credentials ID after creating credentials for connecting to Docker Hub
registryCredential = 'docker-creds'
dockerImage = ''
}

5. Run Pipeline
6.Validate UI
We need Public IP of AKS cluster. Go to AKS Portal in below Image
Check Pods are Running
open public IP without port
