Cayley docker isn't writing data

Question

I'm using [or, trying to use] the docker cayley from here: https://github.com/saidimu/cayley-docker

I created a data dir at /var/lib/apps/cayley/data and dropped the .cfg file in there that I was instructed to make:

{
  "database": "myapp",
  "db_path": "/var/lib/apps/cayley/data",
  "listen_host": "0.0.0.0"
}

I ran docker cayley with:

docker run -d -p 64210:64210 -v /var/lib/apps/cayley/data/:/data saidimu/cayley:v0.4.0

and it runs fine, I'm looking at it's UI in the browser:

And I add a triple or two, and I get success messages.

Then I go to the query interface and try to list any vertices:

> g.V

and there is nothing to be found (I think):

{
 "result": null
}

and there is nothing written in the data directory I created.

Any ideas why data isn't being written?

Edit: just to be sure there wasn't something wrong with my data directory, I ran the local volume mounted docker for neo4j on the same directory and it saved data correctly. So, that eliminates some possibilities.

Answer 1

You may refer to the lib here to learn more about how to use Cayley's APIs and the data format in Cayley and some other stuff like N-Triples N-quads and RDF:

• Cayley APIs usages examples (mocha test cases)
• Clearly designed entry-level N-quads data for getting you in: in the project test/data directory

Answer 2

I can not comment yet but I think to obtain results from your query you need to use the All keyword

g.V().All() // Print All the vertices
OR
g.V().Limit(20) // Limits the results to 20

If that was not your problem I can edit and share my dockerfile which is derived from the same docker-file that you are using.
