Virtuoso Open Source 7

This Docker image is based on the official Docker image by OpenLink. It makes use of the Bulk RDF Loader to import RDF data on the initial startup of the container. It will load your data if it is mounted to /database/toLoad. By default, all data will be loaded into the named graph http://example.com. You can set the name of the default graph via the environment variable DEFAULT_GRAPH. Due to the entrypoint of the official image, this is only triggered if no virtuoso.ini is present. So if you want to use the auto-loading functionallity, configure your instance via environment variables.

Updating virtuoso.ini via environment settings

Note

This is taken from the documentation of the official Docker image by OpenLink!

Using environment variables when creating the Virtuoso docker instance via the command-line options -e, --env, --env-file or via the environment section in a .yml file, you can add or overrule any parameter within the virtuoso.ini file.

These environment variables must be named like:

VIRT_SECTION_KEY=VALUE

where

• VIRT is common prefix to group such variables together (always in upper case)
• SECTION is the name of the [section] in virtuoso.ini (case insensitive)
• KEY is the name of a key within the section (case insensitive)
• VALUE is the text to be written into the key (case sensitive)

The SECTION and KEY parts of these variable names can be written in either uppercase (most commonly used) or mixed case, without having to exactly match the case used inside the virtuoso.ini file. There is no validation on the SECTION and KEY name parts, so any mistake may result in a non-functional setting.

The following names all refer to the same setting:

• VIRT_Parameters_NumberOfBuffers (case matching the section and key name in virtuoso.ini)
• VIRT_PARAMETERS_NUMBEROFBUFFERS (recommended way to name environment variables)
• VIRT_parameters_numberofbuffers (optional)

The VALUE is case sensitive string and should be surrounded by either single (') or double (") quotes in case there are spaces or other special characters in the string.

Example:

$ docker create .... \
  ... \
  -e VIRT_PARAMETERS_NUMBEROFBUFFERS=1000000 \
  -e VIRT_HTTPSERVER_MaxClientConnections=100 \
  -e VIRT_HTTPSERVER_SSL_PROTOCOLS="TLS1.1, TLS1.2" \
  ...

Please note that all path settings in virtuoso.ini should be based on the internal filesystem structure of the docker image, and cannot directly refer to directory paths on the host system. It is possible to bind additional directories from the host system into the docker instance using bind mounts using command-line options such as --mount.
