Environment
===========

You can set ``target_environment`` to specify environment variables that
TPA should set on the target instances during deployment (e.g., to
specify an HTTPS proxy, as shown below).

::

   cluster_vars:
       target_environment:
           https_proxy: https://proxy.example:8080

TPA will ensure these settings are present in the environment (along
with any others it needs) during deployment and the later execution of
any cluster management commands.
