Dan Mick cc10988850 ceph-rest-api: separate into module and front-end for WSGI deploy ... To deploy ceph-rest-api within a WSGI server (apache/mod_wsgi, nginx/uwsgi, etc.), there needs to be an importable (.py) module that performs all init/config when imported. ceph-rest-api was close, but it needs to be named properly, and there's no argument passing, so it needs to get args from a fixed file or the env. Separate most of ceph-rest-api into pybind/ceph_rest_api.py, and make its arguments come from the environment, and init errors be ImportError exceptions. Recase ceph-rest-api as a thin layer that does the usual setup and arg parsing, and then sets args into the environment and imports ceph_rest_api.py, catching exceptions and reporting errors. This allows standalone execution as usual. ceph-rest-api grabs a few module globals (addr/port and the flask.app) to use after it imports. Accept cluster name, and do the ceph.conf search using cluster name in the appropriate places in the searched-for files. Also ceph_rest_api.py gets a little cleanup (fewer global variables, cleaner conf file search algorithm, better error reporting on conf load) Also: doc updates, packaging updates to include ceph_rest_api.py Signed-off-by: Dan Mick <dan.mick@inktank.com>		2013-07-12 16:37:32 -07:00
