How to configure Python pip to look for packages in a private index first?
When I run pip install foo, pip looks for foo in PyPi.
I want it to look for it first in a private repo, let's say pypi.bar.com. Only if foo cannot be found in pypi.bar.com, should pip then look for it in PyPi.
How can I configure pip to do this?

The pip command accepts an option --index-url to specify the primary index (defaults to PyPI) and zero or more --extra-index-url options to specify secondary indices. So for your use case, try
pip install --index-url https://pypi.bar.com/simple --extra-index-url https://pypi.org/simple foo
(where I had to assume that your index uses https:// and /simple for the actual index). If you want to configure this permanently and globally, add to your pip.conf
[global]
index-url = https://pypi.bar.com/simple
extra-index-url = https://pypi.org/simple
If you want to switch between these two, perhaps instead define a shell function with these options for when you want to use them.
ipi () {
local cmd=$1
shift
pip "$1" --index-url https://pypi.bar.com/simple \
--extra-index-url https://pypi.org/simple "$@"
}
(This is for Bourne-compatible shells; if you are on Windows or using some more arcane shell, see their docs.)
See also the pip install section and the pip.conf section of the pip documentation.
