 Docker JMX exporter for Prometheus
 ==================================
 
 Essentially another dockerised JMX Exporter image, this uses alpine-java and dumb-init to provide a relatively small image (approx 130Mb) and includes a released version of jmx_exporter from the [maven central repository](https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_httpserver/)
 
-Available on [Docker hub](https://hub.docker.com/r/sscaling/jmx-prometheus-exporter/)

 Building docker image
 ---------------------
 
 ```
-docker build -t sscaling/jmx-prometheus-exporter .
+docker build -t reasland/jmx-prometheus-exporter .
 ```
 
+### Build Arguments
+
+Additionally, the following build arguments can be defined
+
+-	version - default 0.14.0 - what version of the jmx_exporter http server to use (if you are going to docker push, please tag prom_jmx:$VERSION)
+-	jar - default jmx_prometheus_httpserver-$VERSION-jar-with-dependencies.jar - what jar file from the maven repo https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_httpserver/ to use
+
 Running
 -------
 
 ```
-docker run --rm -p "5556:5556" sscaling/jmx-prometheus-exporter
+docker run --rm -p "5556:5556" reasland/jmx-prometheus-exporter
 ```
 
 Then you can visit the metrics endpoint: [http://127.0.0.1:5556/metrics](http://127.0.0.1:5556/metrics) (assuming docker is running on localhost)
@@ -29,7 +34,7 @@ Configuration
 By default, the jmx-exporter is configured to monitor it's own metrics (as per the main repo example). However, to provide your own configuration, mount the YAML file as a volume
 
 ```
-docker run --rm -p "5556:5556" -v "$PWD/config.yml:/opt/jmx_exporter/config.yml" sscaling/jmx-prometheus-exporter
+docker run --rm -p "5556:5556" -v "$PWD/config.yml:/opt/jmx_exporter/config.yml" reasland/jmx-prometheus-exporter
 ```
 
 The configuration options are documented: [https://github.com/prometheus/jmx_exporter](https://github.com/prometheus/jmx_exporter)
