【k8s】使用k8s部署一个简单的nginx应用

1、 创建命令空间

 kubectl create namespace test

2、编辑 nginx-deployment.yaml

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
  namespace: test
  labels:
    app: nginx
spec:
  replicas: 2
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
        - name: nginx
          image: nginx:latest
          imagePullPolicy: IfNotPresent
          ports:
            - name: http
              protocol: TCP
              containerPort: 80
          resources:
            limits:
              cpu: "1.0"
              memory: 512Mi
            requests:
              cpu: "0.5"
              memory: 128Mi
---
apiVersion: v1
kind: Service
metadata:
  annotations:
  name: nginx-test-service
  namespace: test
spec:
  ports:
    - port: 80
      targetPort: 80
      nodePort: 32001
      protocol: TCP
  selector:
    app: nginx
  sessionAffinity: None
  type: NodePort

3、发布nginx应用

kubectl create -f nginx-deployment.yaml

4、查看发布的pods

 kubectl get pods -n test

 详细查看，注意部署的node节点

kubectl get pods -n test -o wide

 查看服务和pods

kubectl get pods,svc -n test -o wide

 注意服务端口为32001

5、访问nginx服务，node1节点的ip是192.168.143.134，服务端口32001

至此，简单发布完成
