[英]Galera mysql cluster fails to start in Kubernetes
好的,所以我正在使用此倉庫的修改版: https : //github.com/CaptTofu/mysql_replication_kubernetes/tree/master/galera_sync_replication
修改后的文件為:

pxc1,其相同的復制控制器,用於發現和持久卷聲明2和3的服務,只是更改了數字

幾天前它正在運行,並且進行了很多測試,測試了吊艙,節點的運行情況,並研究了復制投票的工作原理,以及一切正常工作。現在,當我集成到應用程序時,它將無法啟動,而且我無法了解為什么它的配置與之相同,為什么我在Internet,SO,GitHub上進行了很多查找,並嘗試了建議的修復程序,但無法正常工作。

有什么建議么? 現在已經幾個小時了,只是無法正常工作
Percona XtraDB Cluster現在對Kubernetes具有本機支持。 PXC運營商幾周前發布了GA 1.0。 https://percona.com/doc/kubernetes-operator-for-pxc/index.html
