AWS, Gotchas 1 Minute

The other thing you’ll run into using IAM users in AWS CLI is that a lot of things don’t support SSO sessions anyway. If you configure an IAM user with an SSO session name as recommended you’ll get errors like this:

$ eb init -p python-3.8 eb-flask-app
ERROR: InvalidConfigError - The profile "default" is configured to use SSO but is missing required configuration: sso_start_url, sso_region

and this:

$ terraform apply
| Error: configuring Terraform AWS Provider: loading configuration: profile "default" is configured to use SSO but is missing required configuration: sso_region, sso_start_url

You can fix these by configuring without an SSO session:

$ aws configure sso
SSO session name (Recommended): 
WARNING: Configuring using legacy format (e.g. without an SSO session).
Consider re-running "configure sso" command and providing a session name.
SSO start URL [None]: https://whatever.awsapps.com/start
SSO region [None]: us-east-1
 ...

You can also fix them by just editing your ~/.aws/config, and copying the sso_start_url and sso_region keys from the [sso-session ...] section into the relevant user’s section, but that might be a hack too far!
