将 YAML 转换为 JSON 时出错：yaml：第 21 行：找到违反缩进的制表符

Question

获取以下 deployment.yaml 的错误：

admin@ip-172-20-58-79:~/kubernetes-prometheus/kube-state-metrics-configs$ kubectl apply -f deployment.yaml

更新 2：根据 Arghya Sadhu 的建议添加了 nodeSelector

更改端口后现在得到：

Answer 1

我尝试了 yaml，它给了我这个错误

error: unable to recognize "kube-state-metrics.yaml": no matches for kind "Deployment" in version "apps/v1beta1"

我将 apps/v1beta1 更改为 apps/v1 来解决它，但我没有收到您报告的错误。

这是我使用的yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app.kubernetes.io/name: kube-state-metrics
    app.kubernetes.io/version: v1.8.0
  name: kube-state-metrics
  namespace: kube-system
spec:
  replicas: 1
  selector:
    matchLabels:
      app.kubernetes.io/name: kube-state-metrics
  template:

        args:
        - --kubelet-insecure-tls
        - --kubelet-preferred-address-types=InternalIP,ExternalIP,Hostname
        livenessProbe:
          httpGet:
            path: /healthz
            port: 8080
          initialDelaySeconds: 5
          timeoutSeconds: 5
        name: kube-state-metrics
        ports:
        - containerPort: 8080
          name: http-metrics
        - containerPort: 8081
          name: telemetry
        readinessProbe:
          httpGet:
            path: /
            port: 8081
          initialDelaySeconds: 5
          timeoutSeconds: 5
      nodeSelector:

我看不出给定的 yaml 有问题。我检查并部署成功。但是，仔细检查第 21 行没有使用制表符进行缩进，然后重新部署相同的 yaml。

也尝试在 v1.9.2 中部署 yaml

 apiVersion: apps/v1
 kind: Deployment
 metadata:
   labels:
     app.kubernetes.io/name: kube-state-metrics
     app.kubernetes.io/version: v1.9.2
   name: kube-state-metrics
   namespace: kube-system
 spec:
   replicas: 1
   selector:
     matchLabels:
       app.kubernetes.io/name: kube-state-metrics
   template:
     metadata:
       labels:
         app.kubernetes.io/name: kube-state-metrics
         app.kubernetes.io/version: v1.9.2
     spec:
       containers:
       - image: quay.io/coreos/kube-state-metrics:v1.9.2
         livenessProbe:
           httpGet:
             path: /healthz
             port: 8080
           initialDelaySeconds: 5
           timeoutSeconds: 5
         name: kube-state-metrics
         ports:
         - containerPort: 8080
           name: http-metrics
         - containerPort: 8081
           name: telemetry
         readinessProbe:
           httpGet:
             path: /
             port: 8081
           initialDelaySeconds: 5
           timeoutSeconds: 5
       nodeSelector:
