У меня ужасное время, когда Terraform берет на себя роль IAM с другой учетной записью, требующей MFA.Вот мои настройки
AWS Config
[default]
region = us-west-2
output = json
[profile GEHC-000]
region = us-west-2
output = json
....
[profile GEHC-056]
source_profile = GEHC-000
role_arn = arn:aws:iam::~069:role/hc/hc-master
mfa_serial = arn:aws:iam::~183:mfa/username
external_id = ~069
AWS Credentials
[default]
aws_access_key_id = xxx
aws_secret_access_key = xxx
[GEHC-000]
aws_access_key_id = same as above
aws_secret_access_key = same as above
