Using Gremlin-Client container and Gremlin-server with neo4j

sorry to bother you. I am trying to set up an ecosystem for a graph database that is going to be used by an application. I am going to use the gremlin-client container:

Gremlin-Console docker

Also i am going to use gremlin-server container:

Gremlin-Server container

And finally i want to use the neo4j container as the storage layer:

Neo4j container

I have read all the docker-files and i was able to connect the console with the server. But now i need to connect the gremlin server container to the neo4j container. I have several links on the web but i was not able to complete this task. It gives me an error of server failure when i tried to connect to neo4j through gremlin-server by running the gremlin-server.sh file . I have downloaded the repository in order to change the docker-file to fit my needs. Does anyone has experience and knows the correct procedure on how to accomplish the connection between the neo4j container with the gremlin server container and making queries through the gremlin console container? Please any help would be really appreciated. Thanks in advance, Juan Ignacio

Since you want to use Neo4j Server you're basically asking how to connect Gremlin Server to a Neo4j Server which was asked in this question. You must either:

  1. Configure the Neo4j graph in Gremlin Server to use HA mode as described here
  2. Configure the Neo4j graph in Gremlin Server to use the Bolt implementation found here

Once you have Gremlin Server connected to Neo4j Server you can then connect Gremlin Console to Gremlin Server through "remoting" discussed here.

In your comments below, you alluded to the fact that you really just want to use Gremlin Console with Neo4j. I brought up the options above because you referenced use of Docker containers and specifically Neo4j Server. Note that you can get going very quickly with Neo4j in embedded mode directly in the Gremlin Console which is discussed in detail here. In that case there is no need for Docker, Neo4j Server, etc.

If you must use Neo4j Server/Docker for some reason and connect to it from the Gremlin Console, then you will still go with one of the two options discussed above, either (1) HA Mode or (2) neo4j-gremlin-bolt but you would simply create those Graph instances in Gremlin Console. For HA mode, that would mean the Gremlin Console would effectively become a node in the Neo4j cluster and for neo4j-gremlin-bolt your Graph instance would just connect over the Bolt protocol.
