Power shell script to deploy war file in application server.

In this article, I will be sharing, basic deployment steps for Java applications, i.e, war files to servers like tomcat, JBoss, WebLogic, or WebSphere.
Deployments steps:
1) Download or Copy war file into deployment server stage location.
2) Stop the service (eg: Jboss service)
3) Take a backup of present war which is already deployed.
4) Copy  new war file from stage location to the deployment location.
5) Start the stopped application service. (eg: JBoss Service)

Here I will be explaining in a windows environment, with the help of PowerShell we will be deploying the war file in server.

Set-ExecutionPolicy Unrestricted

echo " Deploying ${ENV:Rel_Num} "

$ErrorActionPreference = 'Stop'

copy /source/test.war /location/stage

stop-service application-service

copy location\deployments\folder\*.war \location\backup\

Remove-item location/of/deployments/folder/* -recurse

copy /location/stage\test.war location\deployments\folder

start-service application-service

Powershell script to check the status of URL / website is up or not after deployment :-

Generally, after deployment, the website does not come up immediately. It takes 30 seconds to 3 mins or even more sometimes. So, here, I have written the PowerShell script to check whether the status of URL or website has come up or not. This below script can be executed after the deployment is successful. 

Write-Host "Please wait as site is coming up..." -foregroundcolor blue
Write-Host "If it is taking more than 5 mins, please check manually!!" -foregroundcolor blue
Do { 
 Try{

$HTTP_Request = [System.Net.WebRequest]::Create('http://192.168.00.00:8080/test')

$HTTP_Response = $HTTP_Request.GetResponse()
$HTTP_Status = [int]$HTTP_Response.StatusCode

  
Write-Host $HTTP_Status
If ($HTTP_Status -eq 200) { 
     Write-Host "Site is UP!!" -foregroundcolor green
}
$HTTP_Response.Close()
}
 Catch{
   
      }
}
while ($HTTP_Status -ne 200)
