Answer 1

下面的yaml文件中的代码片段有3个问题。

1. 在valueFrom:键下面有一个空格，删除":“之后的空白。
2. 在secretKeyRef键中，'K‘应该是大写字母(secretKeyRef)。
3. secretKeyRef缺少'key‘值。

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

看起来应该是。

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

谢谢,
