To use this library, clone the python-heatclient repository_ from GitHub at ``git://github.com/openstack/python-heatclient.git``. - -Install python-heatclient from source -------------------------------------- - -In the python-heatclient directory, run the install script:: - - sudo ./setup.py install - -Note that python-heatclient may be installed on a different server than heat itself. -Note that pip can be used to install python-heatclient, but the instructions vary for each distribution. Read your distribution documentation if you wish to install with pip. - -Start the OpenStack specific Heat API -------------------------------------- - -When using heat-pythonclient, the OpenStack API service provided by heat must be started:: - - sudo bash -c 'heat-api &' - -List stacks ------------ - -:: - - heat stack-list - -.. - echo; echo 'Success!' +Check out the example templates at ``https://github.com/openstack/heat-templates``.
