A Quick Way to Manage Multiple Amazon AWS Accounts

I’m often switching between different Amazon AWS accounts. So to speed things along I’ve set up some simple scripts to easily switch between accounts while at the command line

On Linux (aws_setup):

export EC2_URL=https://eu-west-1.ec2.amazonaws.com
export EC2_CERT=/home/john/cert-12345678901234567890123456789012.pem
export EC2_PRIVATE_KEY=/home/john/pk-12345678901234567890123456789012.pem</code>

Once saved, run chmod +x aws_setup
On Windows (aws_setup.cmd):

<code>SET EC2_URL=https://eu-west-1.ec2.amazonaws.com
SET EC2_CERT=C:\Users\John\cert-12345678901234567890123456789012.pem
SET EC2_PRIVATE_KEY=C:\Users\John\pk-12345678901234567890123456789012.pem</code>

Save as many files with the paths to your various AWS key pairs, and simply run the script from within a terminal before using the ec2 tools.

NOTE, when you run the scripts on Linux (and I guess Macs), add an extra dot before you run it. This will allow the environment variable to persist when the script ends.

<code>. ./aws_setup</code>
