Docker files for Jena
This repository hosts Docker recipes for distributing Apache Jena.
Two Docker images are available:
- jena -
riot
command 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.
Building
docker build -t jena jena
docker build -t jena-fuseki jena-fuseki
Dockerfile overview
The Dockerfile
s for both images use the official openjdk:11-jre-slim-buster base image, which is based on the [debian](https://hub.docker.com/_/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](https://github.com/stain/jena-docker/blob/master/jena-fuseki/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.
