kubefwd 不适用于特定端口/主机名
我正在使用此命令来运行 kubefwd (https://github.com/txn2/kubefwd)
<代码>sudo kubefwd services -x
这就是日志：
INFO[14:13:58] Port-Forward: 127.1.27.1 sbb-amq:8161 to pod sbb-amq-0:8161
INFO[14:13:58] Port-Forward: 127.1.27.1 sbb-amq:61616 to pod sbb-amq-0:61616
INFO[14:13:58] Port-Forward: 127.1.27.1 sbb-amq:61616 to pod sbb-amq-0:61616
INFO[14:13:58] Port-Forward: 127.1.27.7 idm:9006 to pod idm-0:9006
INFO[14:13:58] Port-Forward: 127.1.27.7 idm:80 to pod idm-0:9006
ERRO[14:14:01] ForwardPorts error: unable to listen on any of the requested ports: [{80 9006}]
我在日志的最后一行收到错误，所以我意识到与端口 80 和 9006 相关的所有主机名都不是附加到 IP，这意味着：
- http://idm:9006 不起作用
- http://127.1.27.7:9006 有效
但是：
- http://sbb-amq:8161 也有效（不使用端口 9006）
有人见过这个吗？
编辑：我使用的是 Ubuntu，端口 80/9006 未使用。
I am using this command to run kubefwd (https://github.com/txn2/kubefwd)
sudo kubefwd services -x <context> -n <namespace> -c <kube_file_path> -l "app in (idm, sbb-amq)"
That is the log:
INFO[14:13:58] Port-Forward: 127.1.27.1 sbb-amq:8161 to pod sbb-amq-0:8161
INFO[14:13:58] Port-Forward: 127.1.27.1 sbb-amq:61616 to pod sbb-amq-0:61616
INFO[14:13:58] Port-Forward: 127.1.27.1 sbb-amq:61616 to pod sbb-amq-0:61616
INFO[14:13:58] Port-Forward: 127.1.27.7 idm:9006 to pod idm-0:9006
INFO[14:13:58] Port-Forward: 127.1.27.7 idm:80 to pod idm-0:9006
ERRO[14:14:01] ForwardPorts error: unable to listen on any of the requested ports: [{80 9006}]
I got an error in the last line of the log, so I have realized that all the hostnames related to ports 80 and 9006 were not attached to the IP, which means:
- http://idm:9006 doesn't work
- http://127.1.27.7:9006 works
However:
- http://sbb-amq:8161 works as well (not using the port 9006)
Has anyone seen this before?
EDIT: I am using Ubuntu and the ports 80/9006 are not in use.

无法侦听任何请求的端口通常意味着您的本地工作站上有某些东西正在侦听这些端口，0.0.0.0:80和0.0.0.0在本例中为：9006。 IP0.0.0.0表示它正在侦听所有接口上的这些端口。kubefwd使用本地环回 IP 地址来允许多个服务使用同一端口，这样您就可以拥有127.27.1.1:80 -> someservice:80 和127.27.1.2:80 ->某个其他服务：80。不幸的是，当您的本地应用程序使用
0.0.0.0:80时，您将无法将 80 绑定到任何接口，因为它已被使用。我不知道为什么应用程序经常绑定到每个接口，因为localhost几乎总是指向127.0.0.1。您有几个选择：
127.0.0.1-m 80： 8080 -m 9006:9007unable to listen on any of the requested portsusually means that you have something on your local workstation listening on those ports,0.0.0.0:80and0.0.0.0:9006in this case. The IP0.0.0.0means it's listening to those ports on all interfaces.kubefwduses local loopback IP addresses to allow the same port for multiple services so that you can have127.27.1.1:80 -> someservice:80and127.27.1.2:80 -> someotherservice:80.Unfortunately, when you have local applications using
0.0.0.0:80, you will not be able to bind 80 to any interface, as it is already being used. I don't know why applications often bind to every interface sincelocalhostalmost always points to127.0.0.1.You have a couple of options:
127.0.0.1-m 80:8080 -m 9006:9007
