Embedded graph with Scylla backend in Java
I'm trying to create an embedded graph in Java (using 11) connected to a Scylla cluster. I stood up the Scylla cluster with Docker using the Scylla University instructions linked to in the Janusgraph docs (https://university.scylladb.com/courses/the-mutant-monitoring-system-training-course/lessons/a-graph-data-system-powered-by-scylladb-and-janusgraph/). The cluster and the Janusgraph server is running just fine. I can connect to the server from a gremlin console and run scripts without issue. However, when I try to create an embedded graph in Java, I get errors indicating the connection cannot be made.
To create the graph, I'm using JanusGraphFactory.build().set("storage.backend","cql").set("storage.hostname","172.18.0.3").open()
The hostname IP is the IP for one of the Scylla nodes.
The primary exception seems to be AllNodesFailedException: Could not reach any contact point, make sure you've provided a valid address.
I tried to attach the full stack trace to this post.

Solution
Update: I figured out what I was doing wrong. I needed to bind the port in the docker run command. Adding -p 9042:9042 to the docker command worked.
