Kubernetes MySQL Operator 8.4.0 未准备好（卡在启动时）

772

我已按照说明一步步在 Kubernetes 上部署 MySQL Operator。按照官方页面的说明进行操作。一旦部署没有错误，操作员就没有处于就绪状态。我已经通过清单和 Helm 尝试过，但得到了相同的响应。

https://dev.mysql.com/doc/mysql-operator/en/mysql-operator-installation-kubectl.html

部署后，操作员尚未准备好

$ kubectl get all -n mysql-operator
NAME                                  READY   STATUS    RESTARTS   AGE
pod/mysql-operator-84ffdf9dbc-m2n4c   0/1     Running   0          31s

NAME                             READY   UP-TO-DATE   AVAILABLE   AGE
deployment.apps/mysql-operator   0/1     1            0           31s

NAME                                        DESIRED   CURRENT   READY   AGE
replicaset.apps/mysql-operator-84ffdf9dbc   1         1         0       31s

我在 Kubernetes 1.24 和 1.27 版本上进行了测试，得到了相同的结果。

运营商似乎试图获取 xxx-privsecrets 但找不到它

有人遇到同样的问题并找到解决方案吗？

不客气！

问题在于集群中存在孤立部署，导致操作员需要搜索秘密。解决方案是删除该 InnoDB 集群。
