Question

我有一个带有（kubernetes）Nginx Ingress控制器的Kubernetes集群，具有以下入口规则：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-rules
#  namespace: default

### Virtual hosts ###
spec:

  rules:

  - host: dashboard.example.com
    http:
      paths:
        - path: /
          backend:
            serviceName: test
            servicePort: 443

test应用程序由Tomcat服务器提供服务。

Tomcat的server.xml是：

<?xml version="1.0" encoding="UTF-8"?>
<Server port="8005" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

  <GlobalNamingResources>
    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
  </GlobalNamingResources>

  <Service name="Catalina">

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
        URIEncoding="UTF-8"
               redirectPort="443" />

    <Connector port="443" protocol="org.apache.coyote.http11.Http11NioProtocol"
        sslImplementationName="org.apache.tomcat.util.net.jsse.JSSEImplementation"
        scheme="https" secure="true" URIEncoding="UTF-8"
               maxThreads="150" SSLEnabled="true">
        <SSLHostConfig>
            <Certificate certificateKeystoreFile="conf/odvsdva.p12"
        certificateKeystorePassword="sdvsdvsdvsd"
                         type="RSA" />
        </SSLHostConfig>
    </Connector>

    <Connector port="8009" protocol="AJP/1.3" redirectPort="443" />

    <Engine name="Catalina" defaultHost="localhost">

      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>

      <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true">

        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

      </Host>

    </Engine>
  </Service>
</Server>

当我在浏览器dashboard.example.com中打开时，Ingress中的路径为/时，我得到了Tomcat标准状态页面（如果看到的话，您已经成功安装了Tomcat。恭喜！）。

现在，如果我转到dasboard.example.com/test，则可以打开我的应用程序。

但是，我只想通过导航到dashboard.example.com/来打开应用程序。

因此，我尝试从Ingress中的/更改/test中的路径。但是然后我在浏览器中得到This site can’t be reached。

我没有设置Tomcat，但是我对此知之甚少。我希望以上提供足够的详细信息。

我的k8s群集位于Ubuntu vagrant VM中。

Answer 1

将入口中的路径保留为/

从tomcat中删除现成的ROOT/目录，然后在部署它之前将war文件重命名为ROOT.war。

Answer 2

我相信您正在寻找的东西是nginx.ingress.kubernetes.io/rewrite-target，但是为了插入而不是像在他们的示例中那样将其删除：

kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /test$1
spec:
  rules:    
  - host: dashboard.example.com
    http:
      paths:
        - path: '(/.*)'

如何将流量从Nginx入口路由到应用程序Tomcat服务器
