Thanks Florian. Can you please help me with 

1. the exact ENV code  that I can add to my Docker to enable ConfigurationManagementGraph so that I can apply my own schema (using ConfiguredGraphFactory to create graph and create index) when docker start. 

2. the exact janusgprah env of the above if I use docker-compose to compose 3 containers janusgraph1.0.0-rc2, cassandra, and OpenSearch(ElasticSearch). I put the below lines in the env as you suggested in other email chain, and unfortunately they are not working except the last one. So what am missing here?

gremlinserver.graphs.ConfigurationManagementGraph=/etc/opt/janusgraph/janusgraph.properties

janusgraph.gremlin.graph=org.janusgraph.core.ConfiguredGraphFactory

janusgraph.graph.graphname=ConfigurationManagementGraph

gremlinserver%d.graphs.graph=

gremlinserver.evaluationTimeout=300000

I know the general concept,and I can set other env like gremlinserver.evaluationTimeout. I just can not get ConfiguredGraphFactory work me using docker or docker-compose. 

For now, yes, I get the local installation of janugraph1.0.0-rc2 work (e.g., use ConfiguredGraphFactory  to create graph etc) with the other two containers  by simply invoking janusgprah server with config: 
./bin/janusgraph-server.sh start conf/gremlin-server/gremlin-server-configuration.yaml and initialize it with my own schema,

i was able to inject near million nodes/edges into the graph (3-5 faster than the jansugraph-full version), but I would perfer to not creating my image from source code if there is docker image we can leverage.

Thanks 

Thank you
