aws error argument --region expected one argument when running Kubernetes on AWS

Question

I'm trying to set up kubernetes on aws ubuntu instance.

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

This fails, however...

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

Any help will be appreciated, thank you :)

Answer 1

One problem might be AWS_S3_REGION=us-east-1b. us-east-1b is an availability zone, not a region. You should just use us-east-1

Answer 2

You seem pretty confused with AZ and regions 

Use the ec2-describe-regions command as follows to describe your regions.
PROMPT> ec2-describe-regions REGION us-east-1 
ec2.us-east-1.amazonaws.com REGION ap-northeast-1 
ec2.ap-northeast-1.amazonaws.com REGION ap-southeast-1 
ec2.ap-southeast-1.amazonaws.com .. 
Use the ec2-describe-availability-zones command as follows to describe your Availability Zones within the us-east-1 region. 
PROMPT> ec2-describe-availability-zones --region us-east-1 
AVAILABILITYZONE us-east-1a available us-east-1 
AVAILABILITYZONE us-east-1b available us-east-1 
AVAILABILITYZONE us-east-1c available us-east-1 
AVAILABILITYZONE us-east-1d available us-east-1
