Ingress HTTPS 代理访问

创建证书，以及 cert 存储方式

openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout tls.key -out tls.crt -subj "/CN=nginxsvc/O=nginxsvc"
kubectl create secret tls tls-secret --key tls.key --cert tls.crt

deployment、Service、Ingress Yaml 文件

apiVersion: extensions/v1beta1

metadata:
  name: nginx-test
spec:
  tls:
    - hosts:
      - foo.bar.com
      secretName: tls-secret
  rules:
    - host: foo.bar.com
      http:
        paths:
        - path: /
          backend:

Nginx 进行 BasicAuth

yum -y install httpd
htpasswd -c auth foo
kubectl create secret generic basic-auth --from-file=auth

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-with-auth
  annotations:
    nginx.ingress.kubernetes.io/auth-type: basic
    nginx.ingress.kubernetes.io/auth-secret: basic-auth
    nginx.ingress.kubernetes.io/auth-realm: 'Authentication Required - foo'
spec:
  rules:
  - host: foo2.bar.com
    http:
      paths:
      - path: /
        backend:
          serviceName: nginx-svc
          servicePort: 80

Nginx 进行重写

名称	描述	值
nginx.ingress.kubernetes.io/rewrite-target	必须重定向流量的目标URI	串
nginx.ingress.kubernetes.io/ssl-redirect	指示位置部分是否仅可访问SSL（当Ingress包含证书时默认为True）	布尔
nginx.ingress.kubernetes.io/force-ssl-redirect	即使Ingress未启用TLS，也强制重定向到HTTPS	布尔
nginx.ingress.kubernetes.io/app-root	定义Controller必须重定向的应用程序根，如果它在’/'上下文中	串
nginx.ingress.kubernetes.io/use-regex	指示Ingress上定义的路径是否使用正则表达式	布尔

apiVersion: extensions/v1beta1
