How can I add app-wrappers endpoint to Restplus API documentation?

Question

I have a Flask REST API. I use healthcheck.EnvironmentDump to make it easy to dump the environment where my service is running. Is it possible to add the endpoint to the Swagger documentation generated by Restplus?

Example

requirements.txt

flask
flask-restplus
gitpython
healthcheck

app.py

#!/usr/bin/env python

"""Simple Flask/Swagger/REST-API example."""

from flask import Flask
from flask_restplus import Resource, Api
from healthcheck import EnvironmentDump

app = Flask(__name__)
api = Api(app, doc='/doc')

# wrap the flask app and give a environment url
# TODO: Add this to API
envdump = EnvironmentDump(app, "/environment")


@api.route('/version')
class VersionAPI(Resource):
    def get(self):
        import git
        repo = git.Repo(search_parent_directories=True)
        sha = repo.head.object.hexsha
        return sha


@api.route('/health')
class HealthAPI(Resource):
    def get(self):
        import datetime
        return datetime.datetime.now().isoformat()

if __name__ == "__main__":
    app.run(host='0.0.0.0')

EnvironmentDump and HealthCheck will each install their own handlers for the endpoint, so your get() instances within your defined Resources will not be reached. That being said, providing a stubbed resource is sufficient for it to show up in the Swagger doc generated by Flask-RESTPlus:

health = HealthCheck(app, '/healthcheck')

@api.route('/healthcheck')
class HealthCheckResource(Resource):
    def get(self):
        pass
