  now run the command:
  
  $ curl nginx
  
  that's all.

2.second, if you want to forward remote to the local port, 
  open another terminal and run the command:

  $ sudo k8s-forward-cli switch deployment nginx -n default

  create a http server on localhost:
  
  $ python3 -m http.server --bind 0.0.0.0 80

  $ curl nginx

  if the nginx service's domain is nginx.example.com, you can use the command:
  
  $ curl nginx.example.com

  that's all.

3.recover the switch:

  $ sudo k8s-forward-cli recover deployment nginx -n default

4.clean up:

  $ sudo k8s-forward-cli clean
  
  it will run automatically when the program ends.
  
5.ssh:

  1.forward local to remote:
    
    $ sudo k8s-forward-cli ssh remote 127.0.0.1:12345 local 127.0.0.1:12346 server user@127.0.0.1:22 -L -p 123456
  
  2.forward remote to local:
  
    $ sudo k8s-forward-cli ssh remote 127.0.0.1:12345 local 127.0.0.1:12346 server user@127.0.0.1:22 -R -p 123456
  
  3.socks5:

    $ sudo k8s-forward-cli ssh remote 127.0.0.1:12345 local 127.0.0.1:12346 server user@127.0.0.1:22 -R -p 123456 --proxy socks5
  
  4.tcp:
  
    $ sudo k8s-forward-cli ssh remote 127.0.0.1:12345 local 127.0.0.1:12346 server user@127.0.0.1:22 -R -p 123456 --proxy tcp localhost:12347
  
  5.http:

    $ sudo k8s-forward-cli ssh remote 127.0.0.1:12345 local 127.0.0.1:12346 server user@127.0.0.1:22 -R -p 123456 --proxy http[https]
  
  this will replace the a in the original host with b.
