[yliaog]

thanks for the PR, could you please add the reasoning for the change in the description section of this PR?

[dechristo]

@yliaog did it. Thanks! =)

[yliaog]

thanks for the description, could you please make "Issue #634" point to the issue?

[dechristo]

@yliaog Thanks for your attention. Done.

[yliaog]

could you make fixes in the test below too?
https://github.com/kubernetes-client/python-base/blob/master/config/kube_config_test.py

also Issue #634 points to issue 60, I'm curious where the number #634 come from?

[dechristo]

@yliaog thanks for the help! I fixed the test and renamed the link. Sorry about the #634 , I confused it with some other issue. Do you want me to open a nem PR with the right name for the commit?

[yliaog]

i guess you mean to use standard_b64encode

[yliaog]

no need for new PR, could you squash the two commits into one?

[dechristo]

@yliaog I did it. But one of the unit tests (test_data_given_file) failed. So I replaced base64.encodestring for base64.standard_b64encode in kube_config.py
