+# jenkins-slave-gradle
+Provides a docker image of the gradle runtime for use as a Jenkins slave.
+
+## Build
+`docker build -t jenkins-slave-gradle .`
+
+## Build in OpenShift
+```bash
+oc process -f ../templates/jenkins-slave-generic-template.yml \
+    -p NAME=jenkins-slave-gradle \
+    -p SOURCE_CONTEXT_DIR=jenkins-slaves/jenkins-slave-gradle \
+    | oc create -f -
+```
+For all params see the list in the `../templates/jenkins-slave-generic-template.yml` or run `oc process --parameters -f ../templates/jenkins-slave-generic-template.yml`.
+
+## Run
+For local running and experimentation run `docker run -i -t --rm jenkins-slave-gradle /bin/bash` and have a play once inside the container.
+
+## Jenkins Running
+Add a new Kubernetes Container template called `jenkins-slave-gradle` and specify this as the node when running builds. Set the version of Java you want to use and away you go!
+```bash
+export JAVA_HOME=/path/to/java/version
+gradle clean build
+```
