K8SNginx-Ingress-Controller部署，用域名的方式访问服务

Posted 2022-07-01 键客李大白

一、创建资源

---

完整的yaml清单文件在后面。

[root@lidabai-master app]# kubectl apply -f nginx-ingress-controller.yaml
serviceaccount/nginx-ingress-serviceaccount created

二、查看服务状态

---

查看服务状态是否正常，刚才创建的Pod是放在kube-system名称空间的。

[root@lidabai-master app]# kubectl -n kube-system  get pod

服务状态正常！

三、创建测试的服务

---

$ kubectl apply  -f pod-test.yaml
$ vim pod-test.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
  labels:
    app: nginxx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx
        imagePullPolicy: IfNotPresent
        ports:
         - containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
  name: nginx-svc
spec:
  selector:
    app: nginx
  ports:
    - port: 80
      targetPort: 80
      protocol: TCP

查看服务

[root@lidabai-master app]# kubectl get svc
nginx-svc    ClusterIP   10.108.224.202   <none>        80/TCP    26h

四、创建Ingress

[root@lidabai-master app]# kubectl apply -f ingress-test.yaml
[root@lidabai-master app]# cat ingress-test.yaml
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-ngi
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  ingressClassName: nginx
  rules:
  - host: lidabai.nginx.com    #这里是我们访问的域名
    http:
      paths:
      - path: /
        pathType: Prefix  #匹配类型， Prefix（精确匹配）、
        backend:
          service:
            name: nginx-svc    #这里就是我们刚才创建的service名称
            port:
              number: 80

查看ingress

[root@lidabai-master app]# kubectl get ingress
NAME
