Virtuoso Open Source Edition, a multi model RDF SPARQL triplestore and relational SQL server with the Conductor web admin, behind a per VM login
Virtuoso Open Source Edition is a multi model data server: a single daemon that is at once an RDF / SPARQL triplestore, a relational SQL engine and a built in HTTP server, fronted by the Conductor web administration console. It is the same engine that powers DBpedia. From the browser you can log in to the Conductor, browse the SQL schema, run SQL in the Interactive SQL editor, run SPARQL against the RDF store, and administer the server. Applications reach the same data over the SQL / ODBC / JDBC port and the SPARQL HTTP endpoint.
This cloudimg image installs the official OpenLink Virtuoso 7.2.17 server and its Conductor console and runs them as an unprivileged system user. Both the SQL server and the HTTP server are bound to loopback and are never exposed directly to the network; nginx on port 80 reverse proxies the HTTP server with an unauthenticated /healthz endpoint for load balancer probes. A small sample table and RDF graph are created on first boot so the Conductor and SPARQL editor have content to explore.
No default login. Virtuoso ships the well known dba and dav accounts, so cloudimg rotates BOTH to unique per VM secrets on the first boot of every VM, using Virtuoso's supported offline password mechanism, and initialises a fresh per VM database. There is no default dba/dba or dav/dav credential reachable on any deployed VM, and no secret is shared across VMs or known at image capture.
