在Istio Ingress Gateway上实现SSO

本文主要是介绍在Istio Ingress Gateway上实现SSO，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

 kubectl edit svc istio-ingressgateway -n istio-system

更改端口为 80

kubectl edit svc  keycloak -nkeycloak

 更改为8080

添加域

 

添加客户端

Keycloak上的Access Type共有三类： ◼ confidential：适用于需要执行浏览器登录的应用，客户端会通过client secret来获取access token , 多用于服务端渲染的web系统场景中； ◼ public：适用于需要执行浏览器登录的应用，多运用于使用vue和react实现的前端项目； ◼ bearer-only：适用于不需要执行浏览器登录的应用，只允许携带bearer token访问，多运用于RESTful API的使用场景； 

 

 

 

 添加*

 

多出凭据
