List the VPCs within a certain AWS Region using Java JDK

Question

I am using the AWS Java JDK and I wish to check if a VPC is within a certain region. The jdk provides an AmazonEC2.describeVpcs() request but it does not provide a means for filtering by region. Does anyone know of a workaround for this?

Answer 1

You should be able to set the region when building the AWS Client, before making the AmazonEC2.describeVpcs() call.

AmazonEC2 ec2 = AmazonEC2ClientBuilder.standard()
                    .withRegion(Regions.US_WEST_2)
                    .build();
