This small utility will fetch all the users and emails from a Cognito User Pool of your choice and print a nice file for you.
You can compile it yourself:
sh
cargo install cognito-user-reader
or you can download the executable from GitHub releases and add it to your path.
You need to have previously installed awscli.
python
pip install awscli
Depending on how you have configured AWS, you may need to use something similar to assume-role before using cur in order to access the data:
bash
assume-role your-env
Then, just execute:
bash
cur <pool_id> [-r eu-west-1] [-p] [-s] [-i "id1" "id2"] [-e "a@email.com" "b@email.com"] [-n] [-m]
You will see a new cognito_users.csv file in your working directory with all your user's emails.
If you want to learn more about the options of this cli just execute cur -h.
