I am following the official example to exec into a Kubernetes container using the python kubernetes-client library.

from kubernetes import config
from kubernetes.client.api import core_v1_api
from kubernetes.stream import stream


def exec_commands(api_instance):

    resp = stream(api_instance.connect_get_namespaced_pod_exec,
                  'busybox',
                  'default',
                  command=['/bin/sh'],
                  stderr=True, stdin=True,
                  stdout=True, tty=True,
                  _preload_content=False)

    while resp.is_open():
        resp.update(timeout=1)
        if resp.peek_stdout():
            print("%s" % resp.read_stdout())
        if resp.peek_stderr():
            print("%s" % resp.read_stderr())

        command = input()

        if command == "exit":
            break
        else:
            resp.write_stdin(command + "\n")

    resp.close()


def main():
    config.load_kube_config("~/.kube/config")
    core_v1 = core_v1_api.CoreV1Api()
    exec_commands(core_v1)


if __name__ == '__main__':
    main()

The above code is able to exec into the container. However, the shell is not very interactive. The issues with it are:-

1. Arrow keys do not work. When pressing arrows, exec shows ^[[D^[[C^[[A^[[B characters
2. Tab auto-complete does not work. When I press tab character, it takes tab as input white spaces instead of auto-completing.

3. I have to hit the enter key twice to get the command output. Example:-

   ls
   
   
   / # ls
   abc.txt       etc           root          tmp
   bin           home          sys           usr
   dev           proc          terminfo.src  var
   / # 

4. Cannot work with vi editor inside the container because of not been able to use arrow and escape key. Example:-

first line
^[[C^[[D^[[C^[[B

Is there any better way to exec into a kubernetes container programmatically using python?
