K8S 部署 Nginx

1. 编辑 nginx-deployment 文件

$ vim nginx-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: nginx  # 应用名称
  name: nginx-deployment1   # deployment名称
  namespace: test  # 命名空间
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - image: nginx:1.23.1
        ports:
        - containerPort: 80
        name: nginx
      tolerations:
      - key: "key"
        operator: "Equal"
        value: "nginx"
        effect: "NoSchedule"

2. 创建nginx-deployment

$ kubectl create namespace test
$ kubectl create -f nginx-deployment.yaml

3. 编辑nginx-nodeport文件

$ vim nginx-nodeport.yaml

apiVersion: v1
kind: Service
metadata:
  labels:
   app: nginx  # 应用名称
  name: nginx-deployment1  # deployment名称
  namespace: test  # 命名空间
spec:
  ports:
  - port: 42  # 本服务端口（随便一个）
    name: nginx-service80to31090  # 本服务名称（随便一个）
    protocol: TCP  # 网络协议TCP
    targetPort: 80  # 原服务端口
    nodePort: 31090  # 主机端口
  selector:
    app: nginx  # 应用名称
  type: NodePort  # 网络类型

4. 创建nginx-nodeport

$ kubectl apply -f nginx-nodeport.yaml

5. 访问测试

$ curl 127.0.0.1:31090
