Kubernetes中安裝mysql-operator失敗

Question

因此，我按照指南（https://dev.mysql.com/doc/mysql-operator/en/mysql-operator-installation-kubectl.html）在 Kubernetes Ubuntu Server 22.04 叢集上安裝 MySql 叢集。

我已成功執行以下命令來導入所需的 yaml 部署檔案

kubectl apply -f https://raw.githubusercontent.com/mysql/mysql-operator/trunk/deploy/deploy-crds.yaml
kubectl apply -f https://raw.githubusercontent.com/mysql/mysql-operator/trunk/deploy/deploy-operator.yaml

現在，當我執行部署指令時，pod 會不斷重新啟動。

kubectl get deployment mysql-operator --namespace mysql-operator

這是日誌的輸出（我收到錯誤）

kubectl logs mysql-operator-755b988dd9-jn7f6 --namespace=mysql-operator
exec /usr/bin/mysqlsh: exec format error

這是描述：

任何幫助或想法都會很棒！

Answer 1

你可以看看這個。

一個名為 kubeblocks 的開源工具，用於在 Kubernetes 上部署和管理 MySQL。

我認為它可以解決您的問題。

Answer 2

exec format error 通常表示您正在使用的映像不適合您正在部署的架構。也就是說，您在 AMD64 節點上使用 ARM 映像，反之亦然。

由於 Oracle 容器註冊表上的所有 MySQL 映像都是 AMD64 映像，因此我猜測您的叢集正在 ARM 架構上運行，例如 Ampere 實例。

您將需要在 x64 arch 實例上運行，或找到 ARM 的映像，或前往原始程式碼並重建 ARM 的映像。
