Runs the Gremlin console from the Titan Graph Database's "all" distribution.
|
|
|
|
# Basic Usage
|
|
|
|
To start the Gremlin console with the default configuration files available:
|
|
|
|
docker run -it itzg/titan-gremlin
|
|
|
|
In order to adjust or further define property files to use within Gremlin,
|
|
attach a host directory to the container's `/conf` such as
|
|
|
|
docker run -it -v $(pwd)/conf:/conf itzg/titan-gremlin
|
|
|
|
After running once your host directory will be populated with the distribution-default
|
|
configuration files. Modify those or add to them and they will be available during
|
|
the next time you (re)start your container.
|
|

# Connecting to Cassandra and Elasticsearch Containers
|
|
|
|
First start containers for Cassandra and Elasticsearch (pre-2.x),
|
|
where the `--name` you choose can be arbitrary or left off to use a generated name.
|
|
|
|
docker run -d --name gremlin-cass itzg/cassandra
|
|
docker run -d --name gremlin-es itzg/elasticsearch:1.x
|
|
|
|
Now start Gremlin with networking links to those containers with the aliases
|
|
|
|
* `--link <container>:cass`
|
|
* `--link <container>:es`
|
|
|
|
such as
|
|
|
|
docker run -it --rm --link gremlin-cass:cass --link gremlin-es:es itzg/titan-gremlin
|
|
|
|
and with that you can follow the
|
|
[Graph of the Gods example](http://s3.thinkaurelius.com/docs/titan/current/getting-started.html), such as
|
|
|
|
gremlin> GraphOfTheGodsFactory.load(g)
|
|
gremlin> saturn = g.V.has('name','saturn').next()
|
|
==>v[256]
|
|
gremlin> saturn.map()
|
|
==>name=saturn
|
|
==>age=10000
|
|
gremlin> saturn.in('father').in('father').name
|
|
==>hercules
|

# Running and Connecting with Docker Compose
|
|
|
|
Create the following Compose content as the file `docker-compose.yml` and in
|
|
that directory invoke `docker-compose run titan` to run the Gremlin shell
|
|
with the supporting Elasticsearch and Cassandra containers.
|
|
|
|
```
