-
gateway定义用于配置在mesh边缘,到mesh的tcp和http的负载均衡。
非TLS单主机环境
相关拓扑
-
使用azure aks环境。
-
ingress gateway的service类型为loadbalancer。
-
ingress gateway的service enternal ip为104.211.54.62。
-
通过该external ip对应的域名,访问ingress gateway svc。
-
增加gateway定义。
-
gateway定义中的selector会将该设置与相应的gateway pod绑定。
-
gateway定义中的servers会在相应的pod中生成listener实例,该拓扑中的监听端口为80。
-
需要将80端口注册到该gateway pod对应的服务中(默认已注册)。
-
gateway定义中的hosts表示listener会向哪些特定的虚拟主机转发流量,在该示例中为httpbin.7cb9a9b7b318440399a0.eastus.aksapp.io。
-
增加virtualservice定义。
-
virtualservice定义中的hosts与gateway中的hosts相对应,表示该服务可以注册到gateway的监听中,这个host写会更新到gateway pod路由表的虚拟主机条目中。
-
virtualservice定义中的gateways将virtualservice与gateway关联起来。
-
virtualservice定义中的http定义了路由规则,路由规则会写入到相应gateway pod的路由表中。

TLS多主机环境
相关拓扑
-
使用azure aks环境。
-
ingress gateway的service类型为loadbalancer。
-
ingress gateway的service enternal ip为104.211.54.62。
-
通过该external ip对应的域名,访问ingress gateway svc。
-
2个主机,分别为:httpbin-a.6491dea3ce6b4d17b109.eastus.aksapp.io和httpbin-b.6491dea3ce6b4d17b109.eastus.aksapp.io。
-
客户端使用tls方式访问主机。
-
为2个主机分别配置gateway中的server定义。
-
为2个主机的server定义中增加证书的定义,每个server使用不同的证书。
-
为2个主机分别配置virtualservice定义。
-
在gateway的listnener中生成统一的监听0.0.0.0_443。
-
因为gateway中配置的2个server中有不相同的配置,所以在监听0.0.0.0_443中,会生成2个server,分别为httpbin-a.6491dea3ce6b4d17b109.eastus.aksapp.io和httpbin-b.6491dea3ce6b4d17b109.eastus.aksapp.io。
-
因为监听中生成2个server,所以在路由中会生成2条不同的路由相对应,在gateway的路由中生成分别的虚拟主机https.443.https-httpbina和https.443.https-httpbinb。
-
监听0.0.0.0_443所属的server httpbin-a.6491dea3ce6b4d17b109.eastus.aksapp.io被关联至路由https.443.https-httpbina,server httpbin-b.6491dea3ce6b4d17b109.eastus.aksapp.io被关联至路由https.443.https-httpbinb。
-
主机httpbin-a被路由至pod httpbin-a的/status uri。
-
主机httpbin-b被路由至pod httpbin-b的/headers uri。
