Kubernetes nginx入口控制器重定向

Question

我有一个网站部署在Kubernetes和入口控制器工作。

我需要将旧子域重定向到新子域(old.example.com ->new.example.com)。

我做了一些研究，发现我必须使用注释:

nginx.ingress.kubernetes.io/rewrite-target

my ingress file:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: rancher-ing
namespace: test
annotations:
kubernetes.io/ingress.class: "nginx"
cert-manager.io/cluster-issuer: letsencrypt-prod
kubernetes.io/tls-acme: "true"
ingress.kubernetes.io/secure-backends: "true"
ingress.kubernetes.io/ssl-redirect: "true"
nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
tls:
- hosts:
- new.example.com
secretName: new.example.com
rules:
- host: new.example.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: rancher-logo-service
port:
number: 80
- host: old.example.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: rancher-logo-service
port:
number: 80

Answer 1

我为新url创建了一个入口控制器配置。并将旧的配置更新为:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: rancher-ing-redirect
namespace: test
annotations:
kubernetes.io/ingress.class: "nginx"
cert-manager.io/cluster-issuer: letsencrypt-prod
kubernetes.io/tls-acme: "true"
ingress.kubernetes.io/secure-backends: "true"
ingress.kubernetes.io/ssl-redirect: "true"
nginx.ingress.kubernetes.io/rewrite-target: https://new.example.com/
spec:
rules:
- host: old.example.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: rancher-logo-service
port:
number: 80
