I am actually trying to deploy my application using Kubernetes in the AWS Kops. For this i followed the steps given in the AWS workshop tutorial.

https://github.com/aws-samples/aws-workshop-for-kubernetes/tree/master/01-path-basics/101-start-here

I created a AWS Cloud9 environment by logging in as a IAM user and installed kops and other required software's as well. When i try to create the cluster using the following command

kops create cluster --name cs.cluster.k8s.local --zones $AWS_AVAILABILITY_ZONES --yes

i get an error like below in the cloud9 IDE

error running tasks: deadline exceeded executing task IAMRole/nodes.cs.cluster.k8s.local. Example error: error creating IAMRole: InvalidClientTokenId: The security token included in the request is invalid
        status code: 403, request id: 30fe2a97-0fc4-11e8-8c48-0f8441e73bc3

I am not able to find a way to solve this issue. Any help on this would be appreciable.
