Virtuoso docker

Docker for hosting Virtuoso.

The Virtuoso is built from a specific commit SHA in https://github.com/openlink/virtuoso-opensource.

The Docker image tags include the Virtuoso version installed in the container. The following versions are currently available:

  • 1.0.0-virtuoso7.2.4
  • 1.0.0-virtuoso7.2.2
  • 1.0.0-virtuoso7.2.1
  • 1.0.0-virtuoso7.2.0

Running your Virtuoso

docker run --name my-virtuoso \
    -p 8890:8890 -p 1111:1111 \
    -e DBA_PASSWORD=myDbaPassword \
    -e SPARQL_UPDATE=true \
    -e DEFAULT_GRAPH=http://www.example.com/my-graph \
    -v /my/path/to/the/virtuoso/db:/data \
    -d tenforce/virtuoso

The Virtuoso database folder is mounted in /data.

The Docker image exposes port 8890 and 1111.

The dba password can be set at container start up via the DBA_PASSWORD environment variable. If not set, the default dba password will be used.

The SPARQL_UPDATE permission on the SPARQL endpoint can be granted by setting the SPARQL_UPDATE environment variable to true.

Dumping your Virtuoso data as quads

Enter the Virtuoso docker, open ISQL and execute the dump_nquads procedure. The dump will be available in /my/path/to/the/virtuoso/db/dumps.

docker exec -it my-virtuoso bash
isql-v -U dba -P $DBA_PASSWORD
SQL> dump_nquads ('dumps', 1, 10000000, 1);

Loading quads in Virtuoso

Manually

Make the quad .nq files available in /my/path/to/the/virtuoso/db/dumps. The quad files might be compressed. Enter the Virtuoso docker, open ISQL, register and run the load.

docker exec -it my-virtuoso bash
isql-v -U dba -P $DBA_PASSWORD
SQL> ld_dir('dumps', '*.nq', 'http://foo.bar');
SQL> rdf_loader_run();

Validate the ll_state of the load. If ll_state is 2, the load completed.

select * from DB.DBA.load_list;

Automatically

By default, any data that is put in the toLoad directory in the Virtuoso database folder (/my/path/to/the/virtuoso/db/toLoad) is automatically loaded into Virtuoso on the first startup of the Docker container. The default graph is set by the DEFAULT_GRAPH environment variable, which defaults to http://localhost:8890/DAV.
