ingress controller 注解使用

官網github注解地址:

https://github.com/kubernetes/ingress-nginx/blob/master/docs/user-guide/nginx-configuration/annotations.md

#http 跳轉到https
nginx.ingress.kubernetes.io/ssl-redirect: 'true'
#即使未啟用TLS，也強制將重定向到HTTPS
nginx.ingress.kubernetes.io/force-ssl-redirect: 'true'

#abc.com 跳轉到www.abc.com
nginx.ingress.kubernetes.io/from-to-www-redirect: 'true'

#session affinity
nginx.ingress.kubernetes.io/affinity: 'cookie'

#開啟路徑正則匹配
nginx.ingress.kubernetes.io/use-regex: 'true'

#uri重定向
nginx.ingress.kubernetes.io/rewrite-target: 'string'
#示例：
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /$2
  name: rewrite
  namespace: default
spec:
  rules:
  - host: rewrite.bar.com
    http:
      paths:
      - backend:
          serviceName: http-svc
          servicePort: 80
        path: /something(/|$)(.*)

在此入口定義中，捕獲的任何字符(.*)都將分配給占位符$2，然后將其用作rewrite-target注釋中的參數。

例如，上面的入口定義將導致以下重寫：

rewrite.bar.com/something 重寫為 rewrite.bar.com/
rewrite.bar.com/something/ 重寫為 rewrite.bar.com/
rewrite.bar.com/something/new 重寫為 rewrite.bar.com/new

#定義應用根路徑
nginx.ingress.kubernetes.io/app-root: 'string'
#示例：
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/app-root: /app1
  name: approot
  namespace: default
spec:
  rules:
  - host: approot.bar.com
    http:
      paths:
      - backend:
          serviceName: http-svc
          servicePort: 80
        path: /
        
$ curl -I -k http://approot.bar.com/
