virtualenv - Python virtual environments

Synopsis:

fpm -s virtualenv [other options] EGG_SPEC|requirements.txt

FPM has support for building packages that provide a python virtualenv from a single egg or from a requirements.txt file. This lets you bundle up a set of python dependencies separate from system python that you can then distribute.

Note

virtualenv support requires that you have virtualenv and the virtualenv-tools binary on your path. This can usually be achieved with pip install virtualenv virtualenv-tools.

Example uses:

Build an rpm package for ansible:

fpm -s virtualenv -t rpm ansible
yum install virtualenv-ansible*.rpm
which ansible # /usr/share/python/ansible/bin/ansible

Create a debian package for your project’s python dependencies under /opt:

echo 'glade' >> requirements.txt
echo 'paramiko' >> requirements.txt
echo 'SQLAlchemy' >> requirements.txt
fpm -s virtualenv -t deb --name myapp-python-libs \
  --prefix /opt/myapp/virtualenv requirements.txt

Create a debian package from a version 0.9 of an egg kept in your internal pypi repository, along with it’s external dependencies:

fpm -s virtualenv -t deb \
  --virtualenv-pypi-extra-url=https://office-pypi.lan/ \
  proprietary-magic=0.9
