Creating a policy version

The following code creates a new policy version for a specific customer-managed policy:

String newPolicyDocument = readFromFile("NewPolicyDocument.json");

  
updatePolicy(policyARN, newPolicyDocument); 
 
........ 
 
public String updatePolicy(
         String policyARN,
         String policyDocument) { 

     CreatePolicyVersionRequest createPolicyVersionRequest =
             new CreatePolicyVersionRequest()
                     .withPolicyArn(policyARN)
                     .withPolicyDocument(policyDocument)
                     .withSetAsDefault(true);

     CreatePolicyVersionResult createPolicyVersionResult =
             amazonIdentityManagement.
                     createPolicyVersion( 
                        createPolicyVersionRequest);

  
    return createPolicyVersionResult 
            .getPolicyVersion() 
            .getVersionId();
 } 
 

The following is the policy document used to create a policy version NewPolicyDocument.json:

{
   "Version": "2012-10-17",
   "Statement": [{
     "Effect": "Allow",
     "Action": [
       "s3:*"
     ],
     "Resource": "arn:aws:s3:::my-bucket-2"
   }]
 }
