需求條件

本主題列出安裝及設定 GKE on AWS 的必要條件。

設定工作站

如要安裝及升級 GKE on AWS 安裝作業，您必須存取執行 Linux 或 MacOS 的工作站。本文件假設您在 Linux 或 macOS 上使用 bash 殼層。如果無法存取一般 Shell 環境，可以使用 Cloud Shell。

工具

如要完成 GKE on AWS 的安裝程序，請先安裝下列工具。

anthos-gke 指令列工具
terraform 指令列工具
kubectl 指令列工具

完成先決條件時，您會安裝這些工具。

網路

設定工作站必須透過通訊埠 443 存取 VPC 網路。

身分與存取權管理權限規定 Google Cloud

如要安裝 GKE on AWS 的 Google Cloud 元件，您需要下列 Identity and Access Management 權限。

專案擁有者: 專案擁有者需要在Google Cloud 專案上啟用 API，該專案會連線至 GKE on AWS 管理服務。
Storage Bucket 擁有者: 在專案中啟用 API 後，您需要具備儲存空間物件管理員權限的使用者。

AWS IAM 權限需求

本節說明從anthos-gke init建立的預設安裝項目，以及安裝至現有 AWS VPC 時，GKE on AWS 需要的 AWS IAM 權限。

使用者必須具備下列存取權：

自動調整資源配置
EC2、
ELB、
IAM、
S3，以及
KMS。

如需特定權限，請參閱以下各節。

AWS Key Management Service (KMS)

GKE on AWS 需要 AWS KMS 金鑰，才能加密叢集中的應用程式層密鑰。安裝 GKE on AWS 之前，您需要與使用者叢集位於相同區域的 KMS Amazon 資源名稱 (ARN)，或建立 KMS 金鑰的權限。

預設安裝

使用 anthos-gke init 安裝 GKE on AWS 時，您需要透過 AWS CLI 設定 AWS IAM 使用者。

專用虛擬私有雲權限

如果您在專屬 VPC 中設定 AWS 上的 GKE，至少需要下列權限。

外連網域存取權

GKE on AWS 需要對下列網域進行輸出存取。

gkeconnect.googleapis.com
gkehub.googleapis.com
oauth2.googleapis.com
storage.googleapis.com
www.googleapis.com
gcr.io
k8s.gcr.io
EC2-REGION.ec2.archive.ubuntu.com

將 EC2-REGION 替換為執行 GKE on AWS 安裝作業的 AWS EC2 區域。例如：us-west-1.ec2.archive.ubuntu.com/。

如果您使用 Cloud Service Mesh with Prometheus and Kiali，請允許從下列網域發出的輸出存取要求：

docker.io
quay.io

工作負載權限

如要在使用者叢集上執行工作負載，不需要 AWS 存取權。您可以使用 Connect 或 OIDC 存取 AWS 上的 GKE 使用者叢集。
