janusGraphEnv

This is a dockerized environment For [JanusGraph + ElasticSearch + Cassandra + GraphExp] What you will get :

• Elasticsearch : 7.10.1 http://localhost:9200
• Kibana : 7.10.1 http://localhost:5601
• JanusGraph : 0.5
• Cassandra : latest
• portainer : latest http://localhost:9000
• graphexp : latest http://localhost:8183
• landing page : http://localhost:8081

Getting Started :

To run the stack you need to set the correct permissions to edit the data folders.

Prerequisites :

• You need to have Docker Engine installed version 18.0 or higher. https://docs.docker.com/install/
• You need to have Docker compose installed too. https://docs.docker.com/compose/install/
• For the elasticsearch container : run : sysctl -w vm.max_map_count=262144 (to know more about it : Virtual memory Elasticsearch)

Installation :

1. To build & run the stack : docker-compose up
2. Go to : http://localhost:9000 & setup for a local docker engine.
3. You are good to go !

If you want to have information to your elasticsearch database content, please download elastic-head plugin and connect to http://localhost:9200

Portal :

To have a bookmark of the environment + useful links : Go to : http://localhost:8081

Use the environment :

Connect remotely to your JanusGraph container & run commands:

As you can see there is an apache-tinkerpop client in the project folder, it has the right version to connect to janusgraph and therefore can be used as a remote gremlin-client for the gremlin-server embedded in JanusGraph.

1. Run a terminal & execute the container run command :

docker run --rm -e GREMLIN_REMOTE_HOSTS=janusgraph -it --network=janusgraph-deployement_janusGraphEnvNetwork janusgraph/janusgraph:latest ./bin/gremlin.sh

Be aware that the network may be different. use docker network ls to find the right docker network to connect to. 2. You need to connect to the gremlin-server on the janusgraph container with this command :

:remote connect tinkerpop.server conf/remote.yaml

3. You need to specify that you want to execute remote commands :

:remote console

4. Now you can run commands with your console in remote to the janusgraph container !
5. Exemples :

gremlin> g.addV('person').property('name', 'chris')
==>v[4160]
gremlin> g.V().values('name')
==>chris

To visualize your Work :

GraphExp is a simple, opensource lighweight solution for visualizing janusgraph content in a browser Using D3.js graphic library. just go to : http://localhost:8183 to access graphExp.

If you want to visualize datas by default, you can load the janusGraph god graph by connecting remotely to the gremlin-server of JanusGraph :

See the documentation here : https://docs.janusgraph.org/getting-started/basic-usage/

To stop properly the stack :

To stop correctly the stack and ensure any kind of data loss do this :

1. Verify that there are no Janusgraph transaction still pending or processing.
2. Go to the root directory of the project (janusGraphEnv/) and do : docker-compose down
