1. 访问 *.xxxxx.com 转发到 *.m.xxxxx.com
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/server-snippet: |
if ($host ~* "(.*).xxxxx.com") {
return 301 http://m.xxxxx.com/$1$request_uri ;
}
name: m-web
namespace: default
spec:
rules:
- host: '*.xxxxx.com'
http:
paths:
- backend:
serviceName: m-web-nginx
servicePort: 80
path: /
tls:
- hosts:
- m.qa.hxtrip.com
secretName: m.qa-https
2. 访问 rewrite.bar.com/something 重定向到 rewrite.bar.com/
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$2
name: rewrite
namespace: default
spec:
rules:
- host: rewrite.bar.com
http:
paths:
- backend:
serviceName: http-svc
servicePort: 80
path: /something(/|$)(.*)
3. 访问 rewrite.bar.com/ 重定向到 - rewrite.bar.com/api/
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/app-root: /api
name: approot
namespace: default
spec:
rules:
- host: approot.bar.com
http:
paths:
- backend:
serviceName: http-svc
servicePort: 80
path: /
4. 访问 host.example.com/service/ ⇒ app1:8080/。如果app1中服务路由并不是定义在根目录(/)，假设我们的实际情况是： host.example.com/service/ ⇒ app1:8080/s1/
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: example-ingress
annotations:
nginx.ingress.kubernetes.io/configuration-snippet: |
rewrite /service/(.*) /s1/$1 break;
spec:
rules:
- host: example.com
http:
paths:
- path: /service/
backend:
serviceName: app1
servicePort: 8080
