Issue
I have a bash script that I run on an AWS EC2 instance (that runs Cloud9 as a development environment), to bootstrap AWS resources for the environment (in this case, my sandbox). I'm configuring the region I'd like to deploy to like this:
aws configure set region "ap-southeast-1"
REGION=$(aws configure get region)
echo $REGION
This isn't correctly setting the $REGION variable. Using set region ... correctly sets the region in ~/.aws/config file on the EC2 instance. My EC2 instance uses AWS managed credentials, which means that my own local AWS region is being stored in the ~/.aws/credentials file on the EC2 instance, which overrides the config file, so aws configure get region returns the region specified in the credentials file. Is there a way of setting and getting the region in an AWS EC2 instance when using managed credentials?
Solution
Please view the order of precedence for setting AWS credentials. Note that running aws configure just creates the credentials file, which is the the 6th item in the precedence list. I suggest using environment variables, the 2nd precedence item.
