I'm having trouble connecting to the kubernetes python client even though I'm following the examples here in the api.

Basically this line can't connect to the kubernetes client:

config.load_kube_config()

What I'm doing:

I have a Dockerfile file like this that I'm building my image with. This is just a simple python/flask app.

FROM python:2

RUN mkdir -p /usr/src/app

WORKDIR /usr/src/app

COPY requirements.txt /usr/src/app/

RUN pip install --no-cache-dir -r requirements.txt

COPY . /usr/src/app

EXPOSE 5000

CMD [ "python", "./app.py" ]

This is my requirements.txt:

Flask==1.0.2
gunicorn==19.8.1
kubernetes==6.0.0
requests # Apache-2.0

After building the Dockerfile it outputs:

    Successfully built a2590bae9fd9
    Successfully tagged testapp:latest

but when I do docker run a2590bae9fd9 I receive an error:

Traceback (most recent call last):
  File "./app.py", line 10, in <module>
    config.load_kube_config()
  File "/usr/local/lib/python2.7/site-     packages/kubernetes/config/kube_config.py", line 470, in load_kube_config
    config_persister=config_persister)
   File "/usr/local/lib/python2.7/site-   packages/kubernetes/config/kube_config.py", line 427, in     _get_kube_config_loader_for_yaml_file
    with open(filename) as f:
 IOError: [Errno 2] No such file or directory: '/root/.kube/config'

I thought it might've been my python directory but I checked and its running in /usr/local/bin/python.

I'm really stumped - any suggestions/tips? thank you.
