[gvm.connections.TLSConnection] ConnectionRefusedError: [Errno 111] Connection refused

Description

Hello everybody,

I am currently using a dockerized version of GVM. gvmd is running in the container.

I am trying to connect to gvmd using python-gvm via a TLSConnection object with the following script:

demo.py

from gvm.connections import DebugConnection, TLSConnection
from gvm.protocols.gmp import Gmp
from gvm.transforms import EtreeTransform
from gvm.xml import pretty_print

tls_connection = TLSConnection()
connection = DebugConnection(tls_connection)
transform = EtreeTransform()

with Gmp(connection, transform=transform) as gmp:
    version = gmp.get_version()
    pretty_print(version)

Given that TLSConnection object is using the following default parameters:

class gvm.connections.TLSConnection(*, certfile=None, cafile=None, keyfile=None, hostname='127.0.0.1', port=9390, password=None, timeout=60)

The command I am using to run the container is:

docker run --detach --publish 8080:9390 (.......) --name <CONTAINER_NAME> <IMAGE_NAME>

Expected behavior

I should get the version:

# python3 demo.py
<get_version_response status="200" status_text="OK">
  <version>21.4</version>
</get_version_response>

Current behavior

Instead, I get an error:

# python3 demo.py

Steps to reproduce

Activate the python virtual environment (with python-gvm)
python3 demo.py
