Signing and verifying images for AWS VPC is crucial for ensuring the integrity and authenticity of your virtual machine images. By signing these images, you can prevent unauthorized alterations and maintain a secure environment. Below are the steps and an example for signing and verifying images.
// Example code for signing an AMI
$imageId = 'ami-12345678'; // Replace with your AMI ID
$keyPairName = 'my-key-pair'; // Your key pair name
// Sign the image using AWS CLI
exec("aws ec2 create-image --instance-id $imageId --name 'My signed AMI' --no-reboot");
// To verify the image
$signedImageId = 'ami-87654321'; // Replace with your signed AMI ID
$imageDetails = shell_exec("aws ec2 describe-images --image-ids $signedImageId");
echo $imageDetails;
