An example project implementing an OpenStack REST API proxy that modifies the API responses before returns it to the client.

Usage

Install and start the proxy server:

$ git clone https://github.com/gibizer/openstack-rest-proxy-example.git
$ cd openstack-rest-proxy-example
$ virtualenv .venv
$ source .venv/bin/activate
$ pip install -r requirements.txt
$ proxy.py  --plugins openstack_rest_proxy.proxy.ResponseAdapterPlugin \
    --port 3128 --host 127.0.0.1

Configure the http_proxy env variable to direct your openstack CLI client to the proxy:

$ export http_proxy=http://127.0.0.1:3128

Modifying API responses

The proxy.ResponseAdapterPlugin is configured via the RESPONSE_ADAPTERS list to call a list of adapters inheriting from adapters.ResponseAdapterBase for each API response before it is returned to the client. The adapters can change the status code, the headers and the body of the response. The adapters.RemovePasswordExpiresAt is an example adapter that removes the password_expires_at key from various Keystone API responses.
