Application login

Default Credential :

• username: demo
• password : demo

Install of Docker and Kubernate on windows

• download Desktop Installer.exe and then follow link https://docs.docker.com/desktop/install/windows-install/
  • once installation is complete then setting --> Kubernates --> Enable Kubernate checkbox --> Apply and restart

Docker Run command

  docker build -t imagepicker:1.0 .

Docker Image named "imagepicker" uploaded on Docker App

Deploy application on Kubernate

similarly install minikube on windows and once installation is complete, we want docker to be executed inside minicube.

New-Item -Path 'c:\' -Name 'minikube' -ItemType Directory -Force
Invoke-WebRequest -OutFile 'c:\minikube\minikube.exe' -Uri 'https://github.com/kubernetes/minikube/releases/latest/download/minikube-windows-amd64.exe' -UseBasicParsing

Add minikube.exe binary to your PATH

$oldPath = [Environment]::GetEnvironmentVariable('Path', [EnvironmentVariableTarget]::Machine)
if ($oldPath.Split(';') -inotcontains 'C:\minikube'){
[Environment]::SetEnvironmentVariable('Path', $('{0};C:\minikube' -f $oldPath), [EnvironmentVariableTarget]::Machine)
}

minikube start :- To start minikube

minikube dashboard To check deployment details

http://127.0.0.1:61873/api/v1/namespaces/kubernetes-dashboard/services/

Below command is to run the docker image inside Kubernetes. (power shell)

minikube start --driver=docker

Next create Kubernetes service object and deployment with port no

kubectl create deployment imagepicker-deployment1 --image=imagepicker:1.0 --port=8080

Check all deployments running

kubectl get deployment

Describe Deployment details

kubectl describe deployment imagepicker-deployment1

Step to create Docker steps are

  docker build -t imagepicker:3.0 .
  docker-compose up

=========================================================================== Some of useful commands for cleanup operation

• Delete a deployment in Kubernetes
• kubectl delete deployment imagepicker-deployment4
• kubectl delete deployment --all --all-namespaces=true

===========================================================================

• Structure of files and resource file structure in the real project

next steps : todo list

• Check why ${responseImagePath} not setting value back to Html form.
• Discuss on MANIFEST.MF file template correct format and what all things we will put going forward in this.
