- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?

我查看了我的 operator 和 mssql2019.yamls(特别是围绕那种:SqlServer,因为这似乎是它失败的地方)并且无法识别任何明显的不一致或差异。
最佳答案
所以你的运营商正在运行:
ag1 pod/pod/mssql-operator-68bcc684c4-rbzvn 1/1 Running 0 86m 10.10.4.133 kw-02.bogus.local <none> <none>
我将首先查看那里的日志:
kubectl -n ag1 logs pod/mssql-operator-68bcc684c4-rbzvn
它很可能需要与云提供商(即 Azure)进行交互,并且不支持 VMware,但请检查日志内容 👀。
