Docker for hosting Virtuoso.
The Virtuoso is built from a specific commit SHA in https://github.com/openlink/virtuoso-opensource.
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.
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);
For more information, see http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtRDFDumpNQuad
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;

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.
