A script to help creating and maintaining frozen requirements for pip
A script to help creating and maintaining frozen requirements for pip.
It is inspired by this Mozilla dev team blog post, who recently switched to pip for deployment.
Basically it downloads packages from one or more pip ‘normal’ requirements files (the ones you use for development, containing only the ‘top level’ dependencies), and outputs the corresponding list of requirements to copy/paste in your frozen production requirements files.
It can also upload the packages to your private pypi repository, and even download the packages from there to save bandwidth.
Install from pypi:
$ sudo pip install freeze-requirements
Or from source:
$ sudo ./setup.py install
If you want to use --upload you also need fabric:
$ sudo pip install fabric
Download packages locally:
freeze-requirements requirements.txt --output /tmp/packages
Process multiple requirements files at once:
freeze-requirements requirements.txt requirements2.txt --output /tmp/packages
Download packages and upload them to a remote host:
freeze-requirements requirements.txt --upload email@example.com:/home/pypi/packages
Same as above but download packages from the remote host. This may be faster as there is no need to upload the packages from your machine and the remote host may have a faster internet connection (pip needs to be installed on the remote host):
freeze-requirements requirements.txt --upload firstname.lastname@example.org:/home/pypi/packages --remote-pip
