AnzoGraph helm - SPARQL Query Port

Question

I have deployed Anzograph using Helm, and have set the config value to enable the SPARQL Endpoint:

azgSettings:
  enable_sparql_protocol: true

but the Services do not expose the expected port 7070 for SPARQL API access.

anzograph-anzograph                          ClusterIP      None             <none>                                                                            12345/TCP                                      10s
anzograph-anzograph-db-lb                    LoadBalancer   172.20.164.162   internal-12345-abc.eu-west-2.elb.amazonaws.com   5600:30415/TCP,5700:31206/TCP,7000:30959/TCP   10s
anzograph-anzograph-frontend-lb              LoadBalancer   172.20.73.121    internal-12345-abc.eu-west-2.elb.amazonaws.com   443:31459/TCP,80:30356/TCP                     10s

How do I access the SPARQL endpoint outside the cluster?

None of the ports exposed via LoadBalancer appear to work. The Port 12345 is labelled as dummy, and doesn't seem to do anything. Querying the pod directly on 7070 (kubectl port-forward pod/anzograph-anzograph-db-0 7070) seems to get further but gives 400 errors and no logs.

Thanks for any help

The SPARQL endpoint is available under a /sparql route on the frontend on port 80. You can access it within the cluster using: http://anzograph-anzograph-frontend-lb:80/sparql, or to get temporary development access externally run:

kubectl port-forward svc/anzograph-anzograph-frontend-lb 8080:80
http://localhost:8080/sparql?query=XYZ
