Kubernetes 嘗試將 jenkins 添加到集群

Question

我是 Kubernetes 的初學者，我嘗試將 jenkins 添加到我的集群中。

當我運行時： kubectl get ns

NAME              STATUS   AGE
srv-dev           Active   77d

我嘗試使用此 yaml 文件在此集群上部署 Jenkins：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: jenkins-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: jenkins
  template:
    metadata:
      labels:
        app: jenkins
    spec:
      containers:
      - name: jenkins
        image: srv-dev/jenkins:lts
        ports:
        - containerPort: 8080
volumeMounts:
          - name: jenkins-home
            mountPath: jenkins_home
      volumes:
        - name: jenkins-home
          emptyDir: {}

並使用此命令： kubectl create -f config_jenkins.yaml --namespace srv-dev但我總是遇到同樣的錯誤：

error: error parsing config_jenkins.yaml: error converting YAML to JSON: yaml: line 22: did not find expected key

您需要更正您的 YAML； alignment 在 YAML 中很重要。 此外，extensions/v1beta1 需要是 apps/v1 如果種類是 Deployment

嘗試這個 -

apiVersion: apps/v1
kind: Deployment
metadata:
  name: jenkins-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: jenkins
  template:
    metadata:
      labels:
        app: jenkins
    spec:
      containers:
      - name: jenkins
        image: srv-dev/jenkins:lts
        ports:
          - containerPort: 8080
        volumeMounts:
          - name: jenkins-home
            mountPath: jenkins_home
      volumes:
        - name: jenkins-home
          emptyDir: {}

你的 yaml 文件應該是這樣的

apiVersion: apps/v1       # -------------This 
kind: Deployment
metadata:
  name: jenkins-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: jenkins
  template:
    metadata:
      labels:
        app: jenkins
    spec:
      containers:
      - name: jenkins
        image: srv-dev/jenkins:lts
        ports:
        - containerPort: 8080
        volumeMounts:             #-------this
        - name: jenkins-home
          mountPath: jenkins_home
      volumes:
      - name: jenkins-home
        emptyDir: {}
