|
||||
|
||||
Using Environment Variables
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Since version 10, pip supports the use of environment variables inside the
|
||||
requirements file. You can now store sensitive data (tokens, keys, etc.) in
|
||||
environment variables and only specify the variable name for your requirements,
|
||||
letting pip lookup the value at runtime. This approach aligns with the commonly
|
||||
used `12-factor configuration pattern <https://12factor.net/config>`_.
|
||||
|
||||
You have to use the POSIX format for variable names including brackets around
|
||||
the uppercase name as shown in this example: ``${API_TOKEN}``. pip will attempt
|
||||
to find the corresponding environment variable defined on the host system at
|
||||
runtime.
|
||||
|
||||
.. note::
|
||||
|
||||
There is no support for other variable expansion syntaxes such as
|
||||
``$VARIABLE`` and ``%VARIABLE%``.

|

Using Environment Variables
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Since version 10, pip also makes it possible to use environment variables which
|
||||
makes it possible to reference private repositories without having to store
|
||||
access tokens in the requirements file. For example, a private git repository
|
||||
allowing Basic Auth for authentication can be refenced like this::
|
||||
|
||||
[-e] git+http://${AUTH_USER}:${AUTH_PASSWORD}@git.example.com/MyProject#egg=MyProject
|
||||
[-e] git+https://${AUTH_USER}:${AUTH_PASSWORD}@git.example.com/MyProject#egg=MyProject
|
||||
|
||||
.. note::
|
||||
|
||||
Only ``${VARIABLE}`` is supported, other formats like ``$VARIABLE`` or
|
||||
``%VARIABLE%`` won't work.
