This repository hosts Docker recipes for distributing Apache Jena.
Two Docker images are available:
- jena -
riotcommand line and friends, for use on the command line - fuseki - the Fuseki 2 server with SPARQL endpoint and web interface
These are currently available from the Docker Hub as:
Note that although these Docker images are based on the official Apache Jena releases and do not alter them in any way, they do not constitute official releases from Apache Software Foundation.
docker build -t jena jena
docker build -t jena-fuseki jena-fusekiThe Dockerfiles for both images use the official openjdk:11-jre-slim-buster base image, which is based on the debian:buster-slim image; this clocks in at about 69 MB
The ENV variables like JENA_VERSION and FUSEKI_VERSION determines which version of Jena and Fuseki are downloaded. Updating the version also requires updating the JENA_SHA512 and FUSEKI_SHA512 variables, which values should match the official Jena download .tar.gz.sha512 hashes, as approved in their release [VOTE] emails.
The ASF_MIRROR use http://www.apache.org/dyn/mirrors/mirrors.cgi that redirect to a local mirror, with a fallback to the ASF_ARCHIVE http://archive.apache.org/dist/ for older versions. Note that due to subsequent sha512 checking these accessed with http rather than https.
To minimize layer size, there's a single RUN with curl, sha512sum, tar zxf and mv - thus the temporary files during download and extraction are not part of the final image.
Some files from the Apache Jena distributions are stripped, e.g. javadocs and the fuseki.war file.
The Fuseki image includes some helper scripts to do tdb loading using fuseki-server.jar.
In addition Fuseki has a docker-entrypoint.sh that populates shiro.ini with the password provided as -e ADMIN_PASSWORD to Docker, or with a new randomly generated password that is printed the first time.
