创建带有重写注解的 Ingress 规则：
$ echo '
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$2
name: rewrite
namespace: default
spec:
ingressClassName: nginx
rules:
- host: rewrite.bar.com
http:
paths:
- path: /something(/|$)(.*)
pathType: Prefix
backend:
service:
name: http-svc
port:
number: 80
' | kubectl create -f -
在此入口定义中，捕获的任何字符(.*)都将分配给占位符$2，然后将其用作rewrite-target注释中的参数。
例如，上面的入口定义将导致以下重写：
-
rewrite.bar.com/something改写为rewrite.bar.com/ -
rewrite.bar.com/something/改写为rewrite.bar.com/ -
rewrite.bar.com/something/new改写为rewrite.bar.com/new
应用根目录
$ echo "
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/app-root: /app1
name: approot
namespace: default
spec:
ingressClassName: nginx
rules:
- host: approot.bar.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: http-svc
port:
number: 80
" | kubectl create -f -
