This application depends on accounts being in your /home/{user}/.aws/config. This means you will need to run the following:

aws configure sso

You will also need to be logged into the sso. To do this run the following command:

aws sso login

Future development will provide a prompt to login if the current login does not exist.

Once you are logged in you can then run:

aws-sso-login

This application is written in go. You can install the application by running the following command in the root of the directory:

go mod tidy
go build

This will produce the aws-sso-login binary which you can then move into a location that is in your PATH:

sudo mv aws-sso-login /usr/local/bin
