好的，所以我正在使用这个 repo 的修改版本：https ://github.com/CaptTofu/mysql_replication_kubernetes/tree/master/galera_sync_replication

修改后的文件是：

服务：

apiVersion: v1
kind: Service
metadata:
  name:  ro-db


  labels:
    unit: pxc-cluster
spec:
  ports:
    - port: 3306
      name: mysql
  selector:
    unit: pxc-cluster

pxc1，它是相同的复制控制器，用于发现的服务以及 2 和 3 的持久卷声明，只是更改了数字

apiVersion: v1
kind: Service
metadata:
  name: pxc-node1
  labels:
    node: pxc-node1
spec:
  ports:
    - port: 3306
      name: mysql
    - port: 4444
      name: state-snapshot-transfer
    - port: 4567
      name: replication-traffic
    - port: 4568
      name: incremental-state-transfer
  selector:
    node: pxc-node1
---
apiVersion: v1
kind: ReplicationController
metadata:
  name: pxc-node1
spec:
  replicas: 1
  template:
    metadata:
      labels:
        node: pxc-node1
        unit: pxc-cluster
    spec:  
      nodeSelector:
        number: '1'

      containers:
        - image: capttofu/percona_xtradb_cluster_5_6:beta
          name: pxc-node1
          ports:

            - containerPort: 4444
            - containerPort: 4567
            - containerPort: 4568
          env:
            - name: GALERA_CLUSTER
              value: "true"
            - name: WRSEP_ON
              value: "true"
            - name: WSREP_CLUSTER_ADDRESS
              value: gcomm://

              value: sst
            - name: WSREP_SST_PASSWORD
              value: sst
            - name: MYSQL_USER
              value: mysql
            - name: MYSQL_PASSWORD
              value: mysql
            - name: MYSQL_ROOT_PASSWORD
              value: c-krit 
          volumeMounts:
            - name: mysql-persistent-storage-1
              mountPath: /var/lib
          securityContext:
            capabilities: {}
            privileged: true #privileged required for mount
      volumes:
      - name: mysql-persistent-storage-1
        persistentVolumeClaim:
          claimName: claim-galera-1
---

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: claim-galera-1
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 4Gi
  selector:
    matchLabels:
      name: pxc1

事情是几天前它还在工作，并进行了大量测试，降低了 Pod、节点，并查看了复制投票和一切工作的方式，现在当我集成到应用程序时，它只是无法启动，我不能理解为什么如果它的配置相同，我在互联网、SO、GitHub 上看了很多，并尝试了建议的修复，但不起作用。

有什么建议么？现在已经有几个小时了，只是无法让它工作

Percona XtraDB 集群现在具有对 Kubernetes 的原生支持。PXC Operator 几周前发布了 GA 1.0。https://percona.com/doc/kubernetes-operator-for-pxc/index.html
