部署 nginx 服务

1. 编写资源文件清单

cat >  nginx.yaml  << "EOF"
---
apiVersion: v1
kind: ReplicationController
metadata:
  name: nginx-web
spec:
  replicas: 2
  selector:
    name: nginx
  template:
    metadata:
      labels:
        name: nginx
    spec:
      containers:
        - name: nginx
          image: nginx:1.19.6
          ports:
            - containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
  name: nginx-service-nodeport
spec:
  ports:
    - port: 80
      targetPort: 80
      nodePort: 30001
      protocol: TCP
  type: NodePort
  selector:
    name: nginx
EOF

2. 创建资源

kubectl apply -f nginx.yaml

3. 查看 pod 是否成功创建

kubectl get pods -o wide

4. 查看 svc 信息

kubectl get svc
