Exception thrown during POST /v2/apps/

[hankjacobs]

Hello!

An exception is being thrown during a POST to /v2/apps/. The stacktrace is at the end of this issue. I've tried to reproduce the issue locally using the ca.crt file found at '/var/run/secrets/kubernetes.io/serviceaccount/ca.crt' but cannot (see snippet used below). Disabling tls verification resolves the issue but is not a valid solution in my opinion. Insight / assistance / suggestions would be appreciated.

>>> import requests
>>> session = requests.Session()
>>> session.verify = 'ca.crt'
>>> r = session.get('https://[K8S API URL]:[K8S API PORT]')

This appears at first glance to be a duplicate of https://github.com/deis/workflow/issues/793. Would you mind verifying if it is? Thanks! :)

[hankjacobs]

yup, exactly that. Thank you!
