Trying to call AWS API via PHP

Question

Trying to call an aws api which gives the master IP address. When I'm calling this api via command it is working fine. Using powershell for this. But, I want to call this api UI using php.While calling via php I am not able to call this api.

My powershell script is,

Clear-Host
Clear-History
$Username = "**"
$Password = "***"
$pass = ConvertTo-SecureString -AsPlainText $Password -Force
$Cred = New-Object System.Management.Automation.PSCredential -ArgumentList $Username,$pass
$ips = @() 

Write-Host "----------------------------------"

Try
{
    echo "Creating Instances will start now..."
    python C:\AWS\Distributed-setup-3\CreateInstance.py
}
Catch
{
    echo "Instance not created"
    exit
}

Write-Host "----------------------------------"

echo "Creating setup...."
Start-Sleep -Seconds 60

python C:\AWS\Distributed-setup-3\statusCheck.py

Start-Sleep -Seconds 60

$content = Get-Content C:\AWS\Distributed-setup-3\InstanceId.txt
echo $content

Write-Host "----------------------------------"

ForEach ($id In $content){
    echo "execute.ps1 id"
    echo $id    
    $instances = aws ec2 describe-instances --instance-ids $id --query Reservations[].Instances[].PublicIpAddress 
    $instance = $instances[1]
    $instance = $instance -replace '"' , ""
    $instance =  $instance.Trim()
    $ips = $ips+$instance
}

Write-Host "----------------------------------"

Clear-Content 'C:\AWS\Distributed-setup-3\ipconfig.txt'

ForEach ($i In $ips){
    #echo $i
    if($i -eq ($ips[0])){
        Write-Host "Master is "$i
    }
    else
    {
        Write-Host "Client "$i
        $index = [array]::indexof($ips,$i)
        $index = $index+1
        if($ips[$index] -eq $null){
            $i | Add-Content 'C:\AWS\Distributed-setup-3\ipconfig.txt'
        }
        else{
            $i = $i+","
            $i | Add-Content 'C:\AWS\Distributed-setup-3\ipconfig.txt'
        }
    }
}

Write-Host "----------------------------------"

aws s3 cp C://AWS/Distributed-setup-3/ipconfig.txt s3://s3merahkee
aws s3 cp C://AWS/Distributed-setup-3/Input.yaml s3://s3merahkee


Write-Host "----------------------------------"

Write-Host "Executing jmeter distributed test on remote system" $ips

Write-Host "----------------------------------"

ForEach ($ip In $ips){ 
   if($ip -eq ($ips[0])){
        #echo "Executing hub"
        Write-Host "Master ip is "$ip
   }
   else
   {
        #Write-Host "Executing slave "$ip
        Start-Job "C:\AWS\Distributed-setup-3\instance_2.ps1" -ArgumentList $ip
   } 
}

Start-Sleep -Seconds 60

Write-Host "----------------------------------"

$hub = $ips[0]
echo -n "Executing Master :"$hub

Start-Sleep -Seconds 10
Invoke-Command -ComputerName $hub -ScriptBlock { cmd.exe /c C:\Users\Administrator\Desktop\gitclone.bat } -credential $Cred

Write-Host "----------------------------------"

ForEach ($ip In $ips){
    echo -n "Executing on remote system for reports " $ip
    Try
    {
        Invoke-Command -ComputerName $ip -ScriptBlock { cmd.exe /c C:\Users\Administrator\Desktop\report.bat } -credential $Cred    
    }
    Catch{
        echo "Unable to connect check the remote connection permission"
    }
}

Write-Host "----------------------------------"

ForEach ($id In $content){
    $instances = aws ec2 describe-instances --instance-ids $id --query 'Reservations[].Instances[].PrivateIpAddress' 
    $instance = $instances[1]
    $instance = $instance -replace '"' , ""
    $i =  $instance.Trim()
    #echo $i
    aws s3 cp  s3://s3merahkee/Logs/$i C:\AWS\Distributed-setup-3\Reports --recursive
    cd C:\AWS\Distributed-setup-3\Reports
    Rename-Item jmeter-server.log jmeter-server_$i.log
}

Write-Host "----------------------------------"

echo "Terminating instance"
ForEach ($id In $content){
   aws ec2 terminate-instances --instance-ids $id
}

Write-Host "----------------------------------"
Write-Host "Execution completed"

In php file,

<?php

        ini_set('max_execution_time', 500);
        $output= shell_exec('aws ec2 describe-instances --instance-ids i-03bb2e6b53fcd4335 --query Reservations[].Instances[].PublicIpAddress');
        echo( '<pre>' );
        echo( $output );
        echo( '</pre>' );          
 ?>

Here the api is,

aws ec2 describe-instances --instance-ids $id --query Reservations[].Instances[].PublicIpAddress 

Trying to do it quite a lot time, still unsuccessful in this, can anyone help  ?

Try using AWS SDK for PHP, Link is here:  AMAZON DOCS

Like in this example:

require 'vendor/autoload.php';
use Aws\Ec2\Ec2Client;

$ec2Client = new Ec2Client([
'region' => 'us-west-2',
'version' => '2016-11-15',
'profile' => 'default'
]);
$result = $ec2Client->describeInstances(
  array('InstanceIds' => $ids)
);

Check out this AWS Certification program to learn more about AWS API.

Thanks!
