$ sudo apt-get install python-virtualenv libpq-dev python-all-dev libffi-dev
The python-virtualenv system package provides, unsurprisingly, the Python
virtualenv package. It is used to isolate groups of third-party libraries and
allows for multiple Python projects with conflicting dependencies to be
developed in parallel. libpq-dev is important for some sub-package compilation.
python-all-dev provides some Python.h headers. libffi-dev needed for cryptography.
$ source environment.sh
This will set some environment variables, create and activate a Python
virtualenv and install the dependencies found in requirements.txt. Activating
the virtualenv changes where your shell locates the python and pip
executables and changes where Python locates installed packages. You can see
how all of this is works by examining environment.sh. The virtualenv does not
need to be created in any particular place and environment.sh will respect an
already activated virtualenv. You might consider looking at virtualenvwrapper
(available on Ubuntu via $ sudo apt-get install virtualenvwrapper) as another
way to manage your virtualenvs.
The project dependencies may change from time to time. To trigger a reinstall,
environment.sh supports a -i flag:
$ source environment.sh -i
To reset your environment to its state before sourceing the environment
script, simply run:
$ deactivate
The Ansible module this project uses to run instances in EC2 uses the Python
library boto. It will need a set of AWS credentials to run those instances.
Boto can be configured in a number of ways as described
here. The simplest
method is probably to put them in ~/.boto in the format mentioned in that
document.
$ ansible -m ping localhost
If all is working, you should see some output that indicates ansible was able to
run the ping module on localhost.
