k8s基本操作

1.建立一個服務

kubectl create -f xxx.yaml
           

xxx.yaml檔案的編寫

---

  name: user-service
  labels:
    app: user-service
spec:
  type: NodePort
  ports:
  - port: 80
    nodePort: 30122
  selector:
    app: user-pod
---
apiVersion: apps/v1

metadata:
  name: user-deployment

  selector:
    matchLabels:
      app: user-pod
  replicas: 1
  template:
    metadata:
      labels:
        app: user-pod
    spec:
      containers:
      - name: user-container
        image: flask_ateuser:v1.0
        imagePullPolicy: Never
        ports:
        - containerPort: 80
