Kubernetes通过端口转发映射本地端口到指定的Pod应用端口

将一个或多个本地端口转发到pod。这个命令要求节点安装“socat”。

使用资源类型/名称，如deployment/mydeployment来选择pod。如果省略，资源类型默认为’pod’。

如果有多个pod匹配标准，将自动选择一个pod。转发会话结束

当选择的pod终止时，需要重新运行该命令来恢复转发。

Examples:      # Listen on ports 5000 and 6000 locally, forwarding data to/from ports 5000 and 6000 in the pod      kubectl port-forward pod/mypod 5000 6000      # Listen on ports 5000 and 6000 locally, forwarding data to/from ports 5000 and 6000 in a pod selected by the    deployment    kubectl port-forward deployment/mydeployment 5000 6000      # Listen on ports 5000 and 6000 locally, forwarding data to/from ports 5000 and 6000 in a pod selected by the service      kubectl port-forward service/myservice 5000 6000      # Listen on port 8888 locally, forwarding to 5000 in the pod      kubectl port-forward pod/mypod 8888:5000      # Listen on port 8888 on all addresses, forwarding to 5000 in the pod      kubectl port-forward --address 0.0.0.0 pod/mypod 8888:5000      # Listen on port 8888 on localhost and selected IP, forwarding to 5000 in the pod      kubectl port-forward --address localhost,10.19.21.23 pod/mypod 8888:5000      # Listen on a random port locally, forwarding to 5000 in the pod      kubectl port-forward pod/mypod :5000

• –address=[localhost] 要监听的地址(逗号分隔)。只接受IP地址或本地主机，当提供了localhost时，kubectl将尝试在127.0.0.1和::1上绑定，如果两者都不绑定，则会失败可以绑定地址。
• –pod-running-timeout=1m0s 大于0的等待时间长度(如5s、2m或3h)，直到至少一个豆荚运行
