Question

我创建了一个有状态集合，但是运行kubectl apply -f wordpress-database.yaml和kubectl get statefulset之后，我看到广告连播始终处于零状态（为什么？）：

wordpress-database   0/1     25m

yaml（请不要考虑对齐）

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: wordpress-database
spec:
  selector:
    matchLabels:
      app: blog
  serviceName: "blog"
  replicas: 1
  template:
  metadata:
  labels:
    app: blog 
  spec:

      value: database
    - name: MYSQL_USER
      value: user

      value: database

      value: user

    volumeClaimTemplates:

首先检查您执行statefulset时发生了什么：

// MyComponent.vue
export default {
  // ...
  computed: {
    isFormTouchedOrInvalid() {
      return Object.keys(this.fields).some(key => this.fields[key].touched || this.fields[key].invalid);
    }
  },
  //...
}

您可能没有提供存储，未创建持久卷。检查您是否配置了storageclass或将其设置为默认值。

您的 volumeClaimTemplates 部分应类似于：

<ValidationProvider rules="required" v-slot="{ touched, invalid }">
  <pre>touched:{{touched}} invalid:{{invalid}}</pre>
  <input type="email" v-model="value">
</ValidationProvider>
