【问题描述】：

我正在尝试使用 kubernetes 中的 yaml 文件创建部署，但遇到此特定错误：

服务器出错（BadRequest）：创建“.\deployment_test.yaml”时出错：版本“v1”中的部署无法作为部署处理：v1.Deployment.Spec：v1.DeploymentSpec.Template：v1 .PodTemplateSpec.ObjectMeta: v1.ObjectMeta.Labels: ReadMapCB: expect { or n, but found ", error found in #10 byte of ...|"labels":"test"},"sp|...强>

我的yaml文件如下：

kind: Deployment
metadata:
    labels:
      environment: test
    name: agentstubpod-deployment
spec:
  replicas: 3
  selector: 
    matchLabels: 
      enviroment: test
  minReadySeconds: 10
  strategy: 
    rollingUpdate: 
      maxSurge: 1
      maxUnavailable: 0
    type: RollingUpdate
  template: 
    metadata:
      labels: test
    spec: 
      containers:
      - name: agentstub
        image: some-repo:latest 
---
apiVersion: apps/v1
kind: Deployment
metadata:
    labels:
      environment: test
    name: proxystubpod-deployment
spec:
  replicas: 3
  selector: 
    matchLabels: 
      enviroment: test
  minReadySeconds: 10
  strategy: 
    rollingUpdate: 
      maxSurge: 1
      maxUnavailable: 0
    type: RollingUpdate
  template: 
    metadata:
      labels: test
    spec: 
      containers:
      - name: procyservice
        image: some-repo:latest

这个语法有什么问题？我很难进行部署

【解决方案1】：

有一些错误配置。

第一次部署中缺少 apiVersion
metadata 下方的缩进不正确
您必须包含metadata.name 字段
spec.selector.matchLabels 和 spec.template.metadata.labels 应该匹配。

以下是更正后的示例：

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    environment: test
    name: agentstubpod-deployment
  name: dep1
spec:
  replicas: 3
  selector:
    matchLabels:
      environment: test
  minReadySeconds: 10
  strategy:
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 0
    type: RollingUpdate
  template:
    metadata:
      labels:
        environment: test
    spec:
      containers:
      - name: agentstub
        image: some-repo:latest
