从外部无法访问服务

Question

我无法从外部访问我的服务。首先，这里是我的conf yaml文件：

nginx-pod.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-nginx
  namespace: development
spec:
  selector:
    matchLabels:
      app: my-nginx
  replicas: 2
  template:
    metadata:
      labels:
        app: my-nginx
    spec:
      containers:
      - name: my-nginx
        image: nginx:1.7.9
        ports:
        - containerPort: 80

nginx-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: nginx-service
  namespace: development
spec:
  type: LoadBalancer
  selector:
    app: my-nginx
  ports:
  - name: http
    port: 80
    targetPort: 80
    protocol: TCP

metallb-config.yaml

apiVersion: v1
kind: ConfigMap
metadata:
  namespace: metallb-system
  name: config
data:
  config: |
    address-pools:
    - name: default
      protocol: layer2
      addresses:
      - 51.15.41.227-51.15.41.227

然后我创建了集群。命令 kubectl 获取所有 -o 宽打印：

NAME                            READY   STATUS    RESTARTS   AGE   IP            NODE         NOMINATED NODE

一切正常，而且< code > ku bectl describe service/nginx-service 打印:

curl命令在主服务器curl51.15.41.227打印欢迎来到ngin x blablabla。接下来我试图从另一个网络打开，它不起作用，但是我添加了节点端口，它可以工作curl51.15.41.227:30883。所有这些都是我在裸机上做的。我期望从外部主机发生curl51.15.41.227应该到达结果。我做错了什么？

Answer 1

从外部网络访问时，您绝对应该使用节点端口 30883（随机分配的端口）。否则，它不知道将请求路由到何处。

卷曲http://51.15.41.227:30883

Answer 2

它肯定会与http://51.15.41.227或51.15.41.227:80。您可以按向上按钮来向上投票。
