Creating a policy

The following code creates a customer-managed policy under your AWS account:

String policyName = "AmazonS3FullAccess";
String description = "S3 Full Access On my-bucket";
String policyDocument = readFromFile("PolicyDocument.json");
String policyARN =
    createPolicy(policyName, description, policyDocument);

........

public String createPolicy(
    String policyName,
    String description,
    String policyDocument) {

    CreatePolicyRequest createPolicyRequest =
        new CreatePolicyRequest()
        .withPolicyName(policyName)
        .withDescription(description)
        .withPolicyDocument(policyDocument);

    CreatePolicyResult createPolicyResult =
        amazonIdentityManagement
        .createPolicy(createPolicyRequest);

    return createPolicyResult.getPolicy().getArn();
}

The following is the policy document used to create the policy PolicyDocument.json:

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