在kind中通过ingress访问应用

1 使用配置文件创建kind：

$ cat kind-config.yaml
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
  extraPortMappings:
  - containerPort: 80
    hostPort: 80
    protocol: TCP
  - containerPort: 443
    hostPort: 443
    protocol: TCP
$ kind create cluster --name awx --config ./kind-config.yaml
$ kind export kubeconfig --name awx
$ k get no
NAME                STATUS   ROLES           AGE    VERSION
awx-control-plane   Ready    control-plane   4h4m   v1.27.3

2 安装nginx ingress controller

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/deploy/static/provider/kind/deploy.yaml

3 部署应用和ingress

创建ingress选择path为/nginx，访问的时候直接跟上本地ip或者localhost就可以。

$ cat nginx-web-server.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
  namespace: default
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:latest
        ports:
        - containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
  name: nginx
  namespace: default
spec:
  selector:
    app: nginx
  ports:
    - protocol: TCP
      port: 80
      targetPort: 80
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: nginx
  namespace: default
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
  - http:
      paths:
      - path: /nginx
        pathType: Prefix
        backend:
          service:
            name: nginx
            port:
              number: 80
$ kubectl apply -f nginx-web-server.yaml
deployment.apps/nginx created
service/nginx created
ingress.networking.k8s.io/nginx created

4 访问应用

$ curl localhost/nginx
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
html { color-scheme: light dark; }
body { width: 35em; margin: 0 auto;

</head>
<body>
