Question:
I am trying to automate some stuff on AWS and I am using Java API to do this. I am able to launch number of instances I want, but I am unable to find the right class or method that can fetch me the current state of the instance (like running, stopped etc).
I tried this
DescribeInstanceStatusRequest describeInstance = new DescribeInstanceStatusRequest().withInstanceIds(instances.get(i).getInstanceId());
DescribeInstanceStatusResult attr = ec2.describeInstanceStatus(describeInstance);
List<InstanceStatus> state = attr.getInstanceStatuses();
not sure why the instance status is a list
Can someone please point me to right API call.
Thanks in advance
