This is a simple script to make it easier to use AWS Single Sign On credentials with tools that don't understand the sso entries in an AWS profile.

The script provides the following capabilities:

  • Run a command using AWS SSO credentials
  • Generate a temporary profile in the $AWS_CONFIG_FILE and $AWS_SHARED_CREDENTIALS_FILE file
  • Exporting the AWS SSO credentials
  • Use the credentials via .aws/config
  • Assume a role via AWS SSO

Please note that the script is called aws2-wrap to show that it works with AWS CLI v2, even though the CLI tool is no longer called aws2.


Using pip

pip3 install aws2-wrap

Using brew

brew install aws2-wrap

Run a command using AWS SSO credentials

aws2-wrap [--profile <awsprofilename>] [--exec] <command>

Note that if you are using --exec and <command> contains spaces, it must be surrounded with double-quotation marks.

You can also specify the profile to be used via AWS_PROFILE which then allows the same profile to be used by subsequent tools and commands.


aws2-wrap --profile MySSOProfile terraform plan

aws2-wrap --profile MySSOProfile --exec "terraform plan"

AWS_PROFILE=MySSOProfile aws2-wrap terraform plan

If you are having problems with the use of quotes in the command, you may find one of the other methods works better for you.

Generate a temporary profile in the $AWS_CONFIG_FILE and $AWS_SHARED_CREDENTIALS_FILE file

There are some utilities which work better with the configuration files rather than the environment variables. For example, if you need to access more than one profile at a time.

aws2-wrap --generate --profile $AWS_PROFILE --credentialsfile $AWS_SHARED_CREDENTIALS_FILE --configfile $AWS_CONFIG_FILE --outprofile $DESTINATION_PROFILE

Optionally, you can specify --generatestdout instead of --generate. --outprofile is still required in order to name the section but --credentialsfile and --configfile are ignored. With this command option, the generated credentials will then be output to the console.

Export the AWS SSO credentials

There may be circumstances when it is easier/better to set the appropriate environment variables so that they can be re-used by any aws command.

Since the script cannot directly set the environment variables in the calling shell process, it is necessary to use the following syntax:

eval "$(aws2-wrap [--profile <awsprofilename>] --export)"

For example:

eval "$(aws2-wrap --profile MySSOProfile --export)"

If you are using PowerShell, the equivalent command is:

aws2-wrap --profile MySSOProfile --export | invoke-expression

Use the credentials via .aws/config

If you are using a tool that works with normal AWS credentials but doesn't understand the new AWS SSO credentials, another option is to add a profile to .aws/config that calls the aws2-wrap script.

For example, add the following block to .aws/config:

[profile Wrapped]
credential_process = aws2-wrap --process --profile <awsprofilename>

then, after authentication, you can run any command that uses AWS credentials by specifying the "Wrapped" profile:

aws sso login --profile <awsprofilename>
export AWS_PROFILE=Wrapped
terraform plan

Note that because the profile is being specified via AWS_PROFILE, it is sometimes necessary (as shown above) to set AWS_SDK_LOAD_CONFIG in order to get tools like terraform to successfully retrieve the credentials.

Assume a role via AWS SSO

Your .aws/config file can look like this:

sso_start_url = xxxxxxxxxxxx
sso_region = us-west-2
sso_account_id = xxxxxxxxxxxx
sso_role_name = SSORoleName

[profile account1]
role_arn = arn:aws:iam::xxxxxxxxxxxx:role/role-to-be-assumed
source_profile = default
region = ap-northeast-1

allowing you to then run:

aws2-wrap --profile account1 <command>

and <command> will be run under role-to-be-assumed.


Contributions are more than welcome, particularly if you are able to expand on the test code. Please ensure, though, that before you submit a Pull Request, you run make test to ensure that your changes don't break any of the existing tests and make pylint to ensure that the linter is happy. Please note that the CI/CD pylint test may use different pylint rules from your own local setup.

Please also note that make pylint will only report errors. You may want to explicitly run python3 -m pylint aws2wrap
