urlopen error [Errno 99] Cannot assign requested address

[arunkollan]

Hi There, I am trying to run the REST request for services http://:8083/services/

and I get the following error

File "/bemserver/database/ontology/manager.py", line 144, in _query
bemserver      |     raise SPARQLError(exc)
bemserver      | bemserver.database.ontology.exceptions.SPARQLError: <urlopen error [Errno 99] Cannot assign requested address>

I have set

ONTOLOGY_BASE_URL = 'http://<ipaddress>:3030/bemserver/'

in my default_api_settings.py

it appears the address is not resolved properly thanks for your help.

I am trying to reproduce the problem but cannot do it for the moment. I can see two sources for this issue: 1- Jena/Fuseki is not running: can you check through '$ docker ps'? 2- The 'bemserver' dataset was not created. You can check that running the Fuseki UI (http://localhost:3030/), and checking the datasets created. I just modified the INSTALL file to mention that the Fuseki docker needs to be restarted after copying the bemserver.ttl file in the fuseki docker.

I checked i find the containers are up

I have created docker-compose file and a docker file to create the containers. All you need to do is update the .flaskenv file with these entries. ( not that you don't know :) ) You also need to load the RDF models via the jena web UI

Archive.zip

I tried to access

http://<ipaddress>:8033/occupants/knowledge_levels/

and works without throwing up any error

Thanks for your contribution.

I changed the INSTALL.md and the configuration file for the dataset (bemserver.ttl). You can try to: 1- copy the bemont.rules file in the fuseki docker image: $ docker cp PATH/TO/BEMONT/models/bemont.rules fuseki-data:/fuseki/configuration/ 2- copy the bemserver_ttl file: $ docker cp PATH/TO/bemserver/docs/deployment/data_model/bemserver_tdb.ttl fuseki-data:/fuseki/configuration/ 3- restart the docker image: $ docker restart fuseki

Sorry I forgot to add the bemserver_ttl and the bemont.rules file in my archive. Yes I did what you recommended and the error persists if I try out in a containarised bemserver. This error is not found if I dont install bemserver in a container. There might be some security feature which might cause this issue. I will try digging deep and will let you know. Thank you so much for your help. Much appreciated for your contribution.

Hi, sorry for the delay, but now we built up our docker containers, can you check that it works with these containers? There may be some version problems with the docker containers used... just a guess, I might be wrong.
