mpaws 1.0.2

Execute AWS CLI across multiple profiles and multiple regions in one go

mpaws

mpaws is a Python CLI for running an AWS command across multiple profiles and multiple regions in one go.

This is a time-saver when you are managing dozens of AWS accounts and need to run the same command across all of them.

Installation

pip3 install mpaws

Usage

Set an environment variable MPAWS_PROFILES, and another environment variable MPAWS_REGIONS, then run mpaws command:

export MPAWS_PROFILES=profile1,profile2,profile3
export MPAWS_REGIONS=us-east-1,ap-southeast-2
mpaws ec2 describe-instances

The above command will run aws ec2 describe-instances command for each permutation of the AWS profiles and AWS regions, like these:

AWS_PROFILE=profile1 AWS_DEFAULT_REGION=us-east-1 AWS_REGION=us-east-1 aws ec2 describe-instances
AWS_PROFILE=profile1 AWS_DEFAULT_REGION=ap-southeast-2 AWS_REGION=ap-southeast-2 aws ec2 describe-instances
AWS_PROFILE=profile2 AWS_DEFAULT_REGION=us-east-1 AWS_REGION=us-east-1 aws ec2 describe-instances
AWS_PROFILE=profile2 AWS_DEFAULT_REGION=ap-southeast-2 AWS_REGION=ap-southeast-2 aws ec2 describe-instances
AWS_PROFILE=profile3 AWS_DEFAULT_REGION=us-east-1 AWS_REGION=us-east-1 aws ec2 describe-instances
AWS_PROFILE=profile3 AWS_DEFAULT_REGION=ap-southeast-2 AWS_REGION=ap-southeast-2 aws ec2 describe-instances

Alternatively, you can also run mpaws with multiple AWS profiles against a single AWS region. You can do this by setting the environment variable MPAWS_PROFILES, then run mpaws command:

export MPAWS_PROFILES=profile1,profile2,profile3
mpaws ec2 describe-instances

The above command will run aws ec2 describe-instances command using each AWS profile, combined with the configured AWS region (either via AWS_DEFAULT_REGION, AWS_REGION, or the configured region within the profile definition).

Here's an example if AWS_DEFAULT_REGION is specified with us-east-1 as the value:

AWS_PROFILE=profile1 AWS_DEFAULT_REGION=us-east-1 AWS_REGION=us-east-1 aws ec2 describe-instances
AWS_PROFILE=profile2 AWS_DEFAULT_REGION=us-east-1 AWS_REGION=us-east-1 aws ec2 describe-instances-instances
AWS_PROFILE=profile3 AWS_DEFAULT_REGION=us-east-1 AWS_REGION=us-east-1 aws ec2 describe-instances

Note that each run will also carry over the environment variables available from the original mpaws command run.

Custom command

If you need to run a custom command using each profile, you can use the _ (underscore) character which will tell mpaws to run the custom command AS-IS.

Here's an example:

export MPAWS_PROFILES=profile1,profile2,profile3
export MPAWS_REGIONS=us-east-1,ap-southeast-2
mpaws _ echo \$\{AWS_PROFILE\} \$\{AWS_REGION\}

Which will run the custom command against the permutation of the AWS profiles and AWS regions:

AWS_PROFILE=profile1 AWS_DEFAULT_REGION=us-east-1 AWS_REGION=us-east-1 echo \$\{AWS_PROFILE\} \$\{AWS_REGION\}
AWS_PROFILE=profile1 AWS_DEFAULT_REGION=ap-southeast-2 AWS_REGION=ap-southeast-2 echo \$\{AWS_PROFILE\} \$\{AWS_REGION\}
AWS_PROFILE=profile2 AWS_DEFAULT_REGION=us-east-1 AWS_REGION=us-east-1 echo \$\{AWS_PROFILE\} \$\{AWS_REGION\}
AWS_PROFILE=profile2 AWS_DEFAULT_REGION=ap-southeast-2 AWS_REGION=ap-southeast-2 echo \$\{AWS_PROFILE\} \$\{AWS_REGION\}
AWS_PROFILE=profile3 AWS_DEFAULT_REGION=us-east-1 AWS_REGION=us-east-1 echo \$\{AWS_PROFILE\} \$\{AWS_REGION\}
AWS_PROFILE=profile3 AWS_DEFAULT_REGION=ap-southeast-2 AWS_REGION=ap-southeast-2 echo \$\{AWS_PROFILE\} \$\{AWS_REGION\}

Configuration

Ensure that the profiles specified in MPAWS_PROFILES are already configured in credential file. And the regions specified in MPAWS_REGIONS, AWS_DEFAULT_REGION, AWS_REGION, or AWS configuration are valid regions.

Environment Variable	Mandatory	Example
MPAWS_PROFILES	Yes	profile1,profile2,profile3
MPAWS_REGIONS	No	us-east-1,ap-southeast-2
AWS_DEFAULT_REGION	No	us-east-1
AWS_REGION	No	us-east-1
