Hi. I am using aws auth method to get secrets from vault. That works fine if vault and the ec2 instance requesting the secrets are in the same aws account. The documentation describes the cross account access configuration as following:
For each target AWS account ID, you configure the IAM Role for Vault to assume using the auth/aws/config/sts/<account_id> and Vault will use credentials from assuming that role to validate IAM principals and EC2 instances in the target account.
How can I do that? How can ich configure the access to the other account? How can I see the current configuration?
