docker build command errored with psycopg2 issue

[bsliu17]

Hi mark, first of all awesome tutorial on k8s and django. There's an issue with running docker build command, and the issue is below:

/psycopg2–2.7.3.2.tar.gz (425kB)
 Complete output from command python setup.py egg_info:
 running egg_info
 creating pip-egg-info/psycopg2.egg-info
 writing pip-egg-info/psycopg2.egg-info/PKG-INFO
 writing dependency_links to pip-egg-info/psycopg2.egg-info/dependency_links.txt
 writing top-level names to pip-egg-info/psycopg2.egg-info/top_level.txt
 writing manifest file ‘pip-egg-info/psycopg2.egg-info/SOURCES.txt’
 Error: pg_config executable not found.

I think you mentioned in your medium post that this has been updated, but i still get the issue as of 7/26/2018.

Hi, I fixed it for the one branch but never got around to updating all the other branches, everything should be up to date now, the pyscopg2 version should be 2.7.5.

I was skimming the tutorial so I haven't religiously followed all the steps, but I fixed the error by changing the python version from 3-slim to 3.6 (we can't use 3.7 as of yet).

Yeah, that's one way to fix it, it seems the version update brought about some breaking changes.
