Cayley Docker没有写数据

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

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.

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
