7. 实践案例 - 端口转发

端口转发是 kubectl 的一个子功能，通过 kubectl port-forward 可以将本地端口转发到指定的 Pod。

使用方法

# Listen on ports 5000 and 6000 locally, forwarding data to/from ports 5000 and 6000 in the pod
kubectl port-forward mypod 5000 6000
# Listen on port 8888 locally, forwarding to 5000 in the pod
kubectl port-forward mypod 8888:5000
# Listen on a random port locally, forwarding to 5000 in the pod
kubectl port-forward mypod :5000
# Listen on a random port locally, forwarding to 5000 in the pod
kubectl port-forward mypod 0:5000
