If you’re using bower for some of your projects and may happen to build this not only locally but also in some sort of CI, you might want to have a bower caching proxy in your network.
Installation
I suggest to add a specific user for this:
useradd -m -d /var/cache/bower -s /bin/false bower
Some neccessary packages:
apt-get install git python-virtualenv
Now we install the cache according to the README.
sudo -u bower-cache /bin/bash
cd
virtualenv .
. bin/activate
pip install -U pip setuptools
pip install bower-cache
Configuration
sudo -u bower-cache /bin/bash
cd
bower-cache-init /var/cache/bower/cache
cd cache
python manage.py changepassword admin
We also need to adjust some variables which gets served to the clients.
In cache/bowercachesite/settings.py, we need to set the REPO_URL to a value, where the files being served by git daemon are accessible later for all clients, e.g ```REPO_URL = ‘git://bower-cache.example.com:6789/’````.

Client usage
In your package, add this to .bowerrc:
{
...
"registry": "http://bower-cache.example.com:8000",
...
}
During my tests, the first run timed out on some packages due to the worker being busy fetching the remote repos. Just watch a tool like top or htop until the git processes settles, then try again.
