AWS PROFILE

INTRODUCTION

Managing multiple AWS accounts from aws-cli tends to be a little tedious. When you need to switch between multiple AWS accounts, it seems to be a hassle keeping a track of the current account, all the available account names.

Even setting the variable and using it to switch between accounts doesn't seem like the right deal.

export AWS_PROFILE=user2

Aliases can be used to manage AWS profiles in a better way.

With aliases we can do the following:

List available profiles
View current profile configuration
Switch to another profile

Creating Aliases

First we will create functions that would be invoked by our Alias

Create a file as below:

 vim ~/.awsAliases

Next add the below lines in the file:

#!/bin/bash
function _awsListAll() {

    credentialFileLocation=${AWS_SHARED_CREDENTIALS_FILE};
    if [ -z $credentialFileLocation ]; then
        credentialFileLocation=~/.aws/credentials
    fi
 
    while read line; do
        if [[ $line == "["* ]]; then echo "$line"; fi;
    done < $credentialFileLocation;
};
 
function _awsSwitchProfile() {
   if [ -z $1 ]; then  echo "Usage: awsp profilename"; return; fi
   
   exists="$(aws configure get aws_access_key_id --profile $1)"
   if [[ -n $exists ]]; then
       export AWS_DEFAULT_PROFILE=$1;
       export AWS_PROFILE=$1;
       export AWS_REGION=$(aws configure get region --profile $1);
       echo "Switched to AWS Profile: $1";
       aws configure list
   fi
};

Now if you are using bash, open bash_profile as below:

vim ~/.bash_profile

And add the following files:

. ~/.awsAliases
alias awsall="_awsListAll"
alias awsp="_awsSwitchProfile"
alias awswho="aws configure list"

If you are using zshrc, then add the lines in ~/.zshrc

Now, reload your bash profile or zshrc as below

source ~/.bash_profile # For zshrc source ~/.zshrc

Running Aliases

To list all the profiles use:

awsall

To switch between profiles use:

awsp <profileName>

To show current profile details:

awswho

awsprofile's Issues

Suggest an enhancement: use the region of the default profile in file "config"

I found this very handy:

       export AWS_PROFILE=$1;
       thisProfileRegion=$(aws configure get region --profile $1);
       defaultProfileRegion=$(aws configure get region --profile default);
       export AWS_REGION=${thisProfileRegion:-$defaultProfileRegion};

So that I only need to define region in the "config" file once.
