A fabric utility for creating remote virtual environments, and installing and updating packages.

Project Description
# fabvenv

A fabric utility for creating remote virtual environments, and installing and
updating packages.

The basic use case this covers is logging into a remote host, downloading
virtualenv.py, using it to create a virtual environment for a project,
including installing `pip`, and then installing packages, based on a
"requirements.txt" file.

## Installation

```
pip install fabvenv
```

## Usage

Here is how I define Fabric tasks to create a virtual environment, install
packages, add a directory to the `sys.path` of the python executable, etc.:

```
@task
def venv_create():
require('configured')
venv = fabvenv.Venv(config.venv, config.requirements)
if not venv.exists():
venv.create(config.system_python)


@task
def venv_install():
require('configured')
fabvenv.Venv(config.venv, config.requirements).install()


@task
def venv_upgrade():
require('configured')
fabvenv.Venv(config.venv, config.requirements).upgrade()


@task
def venv_freeze():
require('configured')
fabvenv.Venv(config.venv, config.requirements).freeze()


@task
def venv_remove():
require('configured')
venv = fabvenv.Venv(config.venv, config.requirements)
if venv.exists():
venv.remove()


@task
def venv_pth():
'''
Add the code directory to the virtualenv sys.path.
'''
require('configured')
fabvenv.Venv(config.venv, config.requirements).venv_pth([config.code])
```

## Testing

The file `tests/fabfile.py` is a basic test of using fabric and fabvenv to
create a virtual environment, install a package, upgrade a package, and remove
the virtual environment.

This tests uses an installed version of `fabric` and `fabvenv`. To avoid
having the test conflict with any other installation of `fabvenv`, use a
virtual environment for testing.

Clone fabvenv:

git clone git@github.com:todddeluca/fabvenv.git
cd fabvenv

Install fabric and fabvenv into a virtual environment:

virtualenv ~/tmp/venv
~/tmp/venv/bin/pip install fabric
~/tmp/venv/bin/pip install -e .

The test also assumes that you can do passwordless (keypair) ssh into localhost
as `$USER`.

Run the tests as follows:

cd tests/
~/tmp/venv/bin/fab test_fabvenv
