如何解决“googleapi：错误403：调用者没有权限，禁止”

Question

我正在使用 terraform 在 GCP 中构建基础设施。我正在尝试使用 terraform 将角色分配给service account，但无法这样做。以下是我的代码：

sa.tf:

resource "google_service_account" "mojo-terra" {
  account_id   = "mojo-terra"
  description  = "Service account used for terraform script"
}

resource "google_project_iam_member" "mojo-roles" {
  count = length(var.rolesList)
  role =  var.rolesList[count.index]
  member = "serviceAccount:${google_service_account.mojo-terra.email}"
}

dev.tfvars：

rolesList = [
    "roles/iam.serviceAccountUser"
]

cloudbuild 日志：

Step #2: Error: Error when reading or editing Resource "project \"poc-dev\"" with IAM Policy: Error retrieving IAM policy for project "poc-dev": googleapi: Error 403: The caller does not have permission, forbidden

以下是附加到我的cloudbuild service account 的角色： Custom Role cloudbuild, Cloud Build Service Account, Service Account Admin, Create Service Accounts, Delete Service Accounts, Service Account User, Storage Admin

Answer 1

向 Terraform 提供授权的服务帐户缺少权限 resourcemanager.projects.getIamPolicy，这是错误消息的来源。

服务帐号也缺少更改 IAM 政策所需的权限 resourcemanager.projects.setIamPolicy。

这些权限是角色 roles/resourcemanager.projectIamAdmin（项目 IAM 管理员）的一部分。

列出分配给服务帐户的角色：

gcloud projects get-iam-policy <YOUR GCLOUD PROJECT ID> \
--flatten="bindings[].members" \
--format='table(bindings.role)' \
--filter="bindings.members:<YOUR SERVICE ACCOUNT>"

列出角色包含的权限：

gcloud iam roles describe roles/resourcemanager.projectIamAdmin

将所需角色添加到服务帐户：

gcloud projects add-iam-policy-binding <YOUR GCLOUD PROJECT ID> \
--member=serviceAccount:<YOUR SERVICE ACCOUNT> \
--role=roles/resourcemanager.projectIamAdmin
