[Bug]: controller.info returns less information than juju show-controller

[rgildein]

Description

I'm not sure if this is relevant bug, but I need to get similar information as from juju show-controller using python-libjuju.
Currently there is only addresses, cacert, error and unknown_fields in the output from controller.info(), and I need to get the controller version. I didn't find any way to get this value and I think it should be part of controller.info().

Output obtained with libjuju:

{
      "addresses": [
       "<***>:17070"
      ],
      "cacert": "<***>",
      "error": null,
      "unknown_fields": {}
}

output from juju show-controller

$ juju show-controller u1

Reproduce / Test

import asyncio
from juju.controller import Controller


async def get_info():
    controller = Controller()
    await controller.connect()
    info = await controller.info()
    print(info)

asyncio.run(get_info())

[juanmanuel-tirado]

the controller.info() function is not the same as using the juju CLI show-controller command. The first one only returns the information regarding the current connection with the controller. That's the reason why you don't get all the fields you're looking for.

I don't think there's such a functionality in pythonlib-juju at this moment. You can probably reconstruct this by calling the corresponding functions. If you need this functionality, please open a similar issue as a wishlist item. Meanwhile, I will close this one.

Hi @juanmanuel-tirado, thanks for quick reply. I was not sure if it's by design. I'll open second issue as future request.

I could not use juju directly, because we are working on plugin (Python) which requires to connecting to remote servers.
