Setting the API Server URL bug in Docker container

[vemonet]

The servers url in the OpenAPI yaml definition is not changed by the provided arguments only when run in Docker containers

The exact same command:
openpredict start-api --server-url http://myurl

Works fine locally, the server URL is updated in the OpenAPI definition exposed

When run as entrypoint of a Docker... For some reason the arg is properly passed to the Python code, and the API is well started by the following line (with the right server_url):

api.add_api('openapi.yml', arguments={'server_url': server_url})

But for some reason the started API has en EMPTY servers URL (not even a / which should be the default)

Seems to be an issue with Connexion

[vemonet]

Issue with Connexion default behavior. Multiple issues have been created but the default behavior is to override servers whatever the situation, and Connexion do not seems to provide ways to make sure the servers defined by the user in the openapi.yml file

spec-first/connexion#1174
spec-first/connexion#1139
spec-first/connexion#1047

The culprit: https://github.com/zalando/connexion/blob/master/connexion/apis/flask_api.py#L310

It can be solved by adding a param to disable _spec_for_prefix

An options like self.options.openapi_spec_path

self.options.disable_servers_overwrite = True

Then check it in _spec_for_prefix

Using https://pypi.org/project/flask-reverse-proxy-fix/ can help solve the issue

requirements.txt:

flask-reverse-proxy-fix
werkzeug<1

Code:

from flask_reverse_proxy_fix.middleware import ReverseProxyPrefixFix

api = connexion.App(__name__, options={"swagger_url": ""}, arguments={'server_url': server_url})

api.add_api('openapi.yml')

api.app.config['REVERSE_PROXY_PATH'] = 'http://api.collaboratory.semantiscience.org'
ReverseProxyPrefixFix(api.app)

api.run(host='0.0.0.0', port=port, debug=debug, server=deployment_server)

Great! but the server url is misspelled .

[vemonet]

Yep it works with absolute URIs and relative paths(e.g. /api or v1)

Going to try it with Smart API

[vemonet]

Smart API still not working even with absolute URL: https://smart-api.info/ui/ff8e602615d19577fa3759240dcce951
