docker - 创建 "deployment.yaml": Deployment in version "v1" cannot be handled as a Deployment 时出错

Question

我是 DevOps 的新手。我为刚刚在 Digital Oceans 上创建的 Kubernetes 集群编写了一个 deployment.yaml 文件。创建部署不断出现我现在无法解码的错误。这只是一个测试部署，为我公司的 Web 应用程序迁移到 kubernetes 做准备。

我尝试编辑部署的内容，使其看起来像我发现的常规示例。我什至无法让这个简单的例子起作用。您可以在下面找到 deployment.yaml 内容。

kind: Deployment
apiVersion: apps/v1
metadata:
  name: testit-01-deployment
spec:
  replicas: 4
  #number of replicas generated
  selector:
    #assigns labels to the pods for future selection
    matchLabels:
      app: testit
      version: v01
  template:
    metadata:
      Labels:
        app: testit
        version: v01
    spec:
      containers:
        -name: testit-container
        image: teejayfamo/testit
        ports:
          -containerPort: 80

我在文件夹容器中的 cmd 上运行了这一行:
kubectl apply -f deployment.yaml --validate=false

Error from server (BadRequest): error when creating "deployment.yaml": Deployment in version "v1" cannot be handled as a Deployment: v1.Deployment.Spec: v1.DeploymentSpec.Template: v1.PodTemplateSpec.Spec: v1.PodSpec.Containers: []v1.Container: decode slice: expect [ or n, but found {, error found in #10 byte of ...|tainers":{"-name":"t|..., bigger context ...|:"testit","version":"v01"}},"spec":{"containers":{"-name":"testit-container","image":"teejayfamo/tes|...

我什至无法从搜索中获得任何有关此的信息。我不能只是创建部署。请问，谁理解并可以让我通过？

您的 yaml 文件中存在语法错误。

这应该有效。

  #number of replicas generated

    matchLabels:

      version: v01
  template:

      labels:
        app: testit
        version: v01
    spec:
      containers:
      - name: testit-container
        image: teejayfamo/testit
        ports:
        - containerPort: 80

问题是:

Labels应该是 labels

- name: 的语法和 - containerPort在 spec.containers 中未正确格式化部分。

希望这可以帮助。
