更新：此问题已在Camel K GitHub Issues下回答：https://github.com/apache/camel-k/issues/2693

我有一个Camel K项目，它使用端口4739。现在我只能在登录到Pod容器时将数据发送到端口。
我正在尝试将数据发送到容器之外，有人知道如何配置吗？
已尝试以下命令，但似乎不起作用...

// Split commands into multiple lines for easy read
kamel run 
--trait container.enabled=true  
--trait container.expose=true 
--trait container.port=4739 
--trait service.node-port=true 
SyslogBasic.java --dev

我的理解是容器位于pod内部。首先我们需要将容器端口暴露给pod，然后使用服务将端口暴露给外部，遗憾的是，我还没有找到任何与服务端口相关的命令行。

自Camel K 1.6版起，容器端口的自动配置仅适用于HTTP协议，如以下条件所报告：

Conditions:
  Type              Status  Reason               Message
  ServiceAvailable  False   ServiceNotAvailable  no http service required

您可以使用kamel run --pod-template选项公开容器连接埠，以下列template.yaml档案手动完成此作业：

containers:
  - name: integration
    ports:
      - containerPort: 4739
        protocol: UDP

以及手动创建服务，例如：

$ cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: Service
metadata:
  name: service
spec:
  selector:
    camel.apache.org/integration: sys-log-basic
  ports:
    - protocol: UDP
      port: 4739
      targetPort: 4739
EOF

然后，您可以使用以下项运行集成：

$ kamel run SysLogBasic.java --pod-template template.yaml -d camel-syslog

并使用Netcat发送系统日志跟踪，例如：

$ kubectl run -i --rm debug --image=busybox --restart=Never --command -- sh -c "echo '<34>Oct 11 22:14:15 mymachine su: failed on /dev/pts/8' | nc -u -w1 service 4739"

最后，您可以在集成日志中检查已处理的跟踪，例如：

$ kubectl logs -l camel.apache.org/integration=sys-log-basic
2021-10-14 08:09:36,436 INFO  [io.quarkus] (main) camel-k-integration 1.7.0-SNAPSHOT on JVM (powered by Quarkus 2.2.0.Final) started in 1.684s.
