外部使用 k8s 建置好的服務
安裝
k8s-m1> git clone https://github.com/kubernetes/ingress-nginx.git
k8s-m1> cd ingress-nginx/delpoy/static
修改 mandatory.yaml, 設定 hostNetwork: true
k8s-m1 static > vim mandatory.yaml
annotations:
prometheus.io/port: "10254"
prometheus.io/scrape: "true"
spec:
hostNetwork: true # <-- 加入這行
# wait up to five minutes for the drain of connections
terminationGracePeriodSeconds: 300
serviceAccountName: nginx-ingress-serviceaccount
執行
k8s-m1 static > kubectl apply -f mandatory.yaml
到 k8s-node 查看 80, 443 端口狀況
k8s-n1 > netstat -tunlp
tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 28150/nginx.conf
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 28150/nginx.conf
回到 k8s-m1 設定 service
service-hello.yaml
---
apiVersion: v1
kind: Service
metadata:
name: hello-app
spec:
selector:
app: hello-app
ports:
- protocol: TCP
port: 80
targetPort: 80
k8s-m1 > kubectl apply -f service-hello.yaml
設定 ingress
ingress-hello.yaml
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: nginx-ingress
annotations:
kubernetes.io/ingress.class: "nginx"
spec:
rules:
- host: nginx.testdomain.com
http:
paths:
- path: /hello
backend:
serviceName: hello-app
servicePort: 80
k8s-m1 > kubectl apply -f ingress-hello.yaml
到 要瀏覽的主機 設定 client 的 dns 解析
echo "your-node-ip nginx.testdomain.com" >> /etc/hosts
執行
curl nginx.testdomain.com/hello
完成！！！！！
