失败时重新启动容器而不用新容器替换它

Question

我正在试图找出一种在失败时重启容器的方法，而不是删除并创建一个新的容器来取而代之。能够尝试重新启动它，例如3次，然后停止吊舱将是一个加号。

我有一个看起来像这样的状态（我删除了一些无关紧要的部分）：

apiVersion: "apps/v1beta1"
kind: StatefulSet
metadata:
  name: cassandra-stateful
spec:
  serviceName: cassandra
  replicas: 1
  template:
    metadata:
      labels:
        app: cassandra-stateful
    spec:
      # Only one Cassandra node should exist for one Kubernetes node.
      affinity:
        podAntiAffinity:
          requiredDuringSchedulingIgnoredDuringExecution:
            - labelSelector:
                matchExpressions:
                  - key: "app"
                    operator: In
                    values:
                    - cassandra
              topologyKey: "kubernetes.io/hostname"
      containers:
        - name: cassandra
          image: localrepo/cassandra-kube
          ports:
            - containerPort: 7000
              name: intra-node
            - containerPort: 7001
              name: tls-intra-node
            - containerPort: 7199
              name: jmx
            - containerPort: 9042
              name: cql
          lifecycle:
            preStop:
              exec:
                command: ["pkill java && while ps -p 1 > /dev/null; do sleep 1; done"]

我知道它正在重建pod的原因是我故意用以下方法杀死我的进程：

pkill java && while ps -p 1 > /dev/null; do sleep 1; done

如果我对pod进行描述，我可以看到它重新创建容器而不是重新启动：

$ kubectl describe po cassandra-stateful-0

是否有任何规则可以实现这一目标？
