Adds support for installing python dependencies into a virtualenv on remote
|
|
hosts.
|
|
|
|
Installing python packages directly to the system site-packages can cause
|
|
various problems, in particular when pip overwrites a system package.
|
|
Python virtualenvs are one solution to this issue, as they allow python
|
|
packages to be installed in an isolated environment. Typically we will
|
|
need to enable use of system site-packages from within this virtualenv, to
|
|
support the use of modules such as yum, apt, and selinux, which are not
|
|
available on PyPI.
|
|
|
|
The path to the virtualenv is configured via the ``virtualenv`` variable,
|
|
and access to site-packages is controlled via ``virtualenv_site_packages``.
|
|
The default value for ``virtualenv`` is None, in which case the old
|
|
behaviour of installing packages directly to the system site-packages is
|
|
maintained.
|
|
|
|
When executing other kolla-ansible commands, the variable
|
|
``ansible_python_interpreter`` should be set to the python interpreter
|
|
installed in ``virtualenv``. Note that this variable cannot be templated.
