我正在尝试在 Terragrunt 中利用 Okta 的使用，并且在担任该角色时遇到了一些问题。我的 ~/.aws/config 文件
aws_saml_url = home/amazon_aws/XXXXXXXXX/XXXXXXXXX
[profile assume-admin]
role_arn = arn:aws:iam::XXXXXXXXX:role/assumeAdmin
region = us-west-2
[profile dev]
source_profile = assume-admin
role_arn = arn:aws:iam::XXXXXXXXX:role/adminUser
没有 terragrunt，只使用 Terraform 和 Okta，我看不到任何问题。
$ aws-okta exec dev -- bash
$ terraform plan
Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but will not be
persisted to local or remote state storage.
data.terraform_remote_state.bastion: Refreshing state...
data.terraform_remote_state.vpc: Refreshing state...
data.terraform_remote_state.bastion: Refreshing state...
data.terraform_remote_state.vpc: Refreshing state...
data.aws_caller_identity.current: Refreshing state...
SNIP
Plan: 0 to add, 2 to change, 0 to destroy.
Note: You didn't specify an "-out" parameter to save this plan, so Terraform
can't guarantee that exactly these actions will be performed if
"terraform apply" is subsequently run.
现在使用 Terragrunt
terragrunt plan

谢谢。
