`aws: error: argument --region: expected one argument` when running Kubernetes on AWS
<p>I'm following <a href="http://kubernetes.io/docs/getting-started-guides/aws/" rel="nofollow noreferrer">this guide</a> to set up Kubernetes on an Ubuntu 14.04 image on AWS.</p>

<pre><code>sudo apt-get update
sudo apt-get install curl
sudo apt-get install awscli
aws configure # enter credentials, etc.

# fix `locale` errors
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

export KUBE_AWS_ZONE=us-east-1b
export NUM_NODES=2
export MASTER_SIZE=t2.micro
export NODE_SIZE=t2.micro
export AWS_S3_BUCKET=my.s3.bucket.kube
export AWS_S3_REGION=us-east-1b
export INSTANCE_PREFIX=k8s

export KUBERNETES_PROVIDER=aws
curl -sS https://get.k8s.io | bash
</code></pre>

<p>This fails, however...</p>

<pre><code>ubuntu@ip-172-31-24-216:~$ curl -sS https://get.k8s.io | bash

</code></pre>

<p>I tried editing <code>cluster/aws/util.sh</code> to print out <code>s3_bucket_location</code> (following advice from <a href="https://stackoverflow.com/questions/35664787/nosuchbucket-error-when-running-kubernetes-on-aws">this question</a>, and I get an empty string. I'm guessing that's why it fails?</p>

<p><a href="http://docs.aws.amazon.com/AmazonS3/latest/API/RESTBucketGETlocation.html" rel="nofollow noreferrer">The docs</a> say an empty string for US East is normal, but I tried changing region (with everything else remaining the same) and I still get an empty string.</p>

<p>The s3 bucket does get created.</p>

<p>Any help would be appreciated.</p>
