尝试遵循kubernetes教程[1]示例：使用持久卷部署WordPress和MySQL；
使用cloudshell在Google kubernetes上运行命令“ kubectl apply -f wordpress-deployment.yaml”；
得到此错误：解析wordpress-deployment.yaml时出错：将YAML转换为JSON时出错：yaml：第33行：找不到预期的'：'

Answer 1

yaml文件中的以下代码段存在3个问题。

在以下代码段中，在 valueFrom：键之后有一个空格，请删除“：”之后的空格
在secretKeyRef键中，“ K”应为大写字母（secretKeyRef）。

secretKeyRef缺少“键”值。

- name: WORDPRESS_DB_USER
           valueFrom：
            secretkeyRef:
             name: mysql-pass

应该是这样。

- name: WORDPRESS_DB_USER
          valueFrom:
           secretKeyRef:
            name: mysql-pass
            key: username

谢谢
