 == Openshift
 https://www.openshift.com/[Openshift] is the RedHat public (and enterprise) PaaS solution.
 Like Heroku, it works by running scripts triggered by git commits, so you can script
-the launching of a Spring Boot app in pretty much any way you like as long as the
-Java runtime is available (which is a standard feature you can ask from at Openshift).
-To do this you can use the https://www.openshift.com/developers/do-it-yourself[DIY Cartridge]
-and hooks in your repository under `.openshift/action_scripts`:
+the launching of a Spring Boot application in pretty much any way you like as long as the

+To do this you can use the
+https://www.openshift.com/developers/do-it-yourself[DIY Cartridge] and hooks in your
+repository under `.openshift/action_scripts`:
 
 The basic model is to:
 
-1. Ensure Java and your build tool are installed remotely, e.g. using 
-a `pre_build` hook (Java and Maven are installed by default, Gradle is not)

+1. Ensure Java and your build tool are installed remotely, e.g. using a `pre_build` hook
+   (Java and Maven are installed by default, Gradle is not)
 2. Use a `build` hook to build your jar (using Maven or Gradle), e.g.
 +
+[indent=0]
 ----
-#!/bin/bash
-cd $OPENSHIFT_REPO_DIR
-mvn package -s .openshift/settings.xml -DskipTests=true
+	#!/bin/bash
+	cd $OPENSHIFT_REPO_DIR
+	mvn package -s .openshift/settings.xml -DskipTests=true
 ----
 +
 3. Add a `start` hook that calls `java -jar ...`
 +
+[indent=0]
 ----
-#!/bin/bash
-cd $OPENSHIFT_REPO_DIR
-nohup java -jar target/*.jar --server.port=${OPENSHIFT_DIY_PORT} --server.address=${OPENSHIFT_DIY_IP} &
+	#!/bin/bash
+	cd $OPENSHIFT_REPO_DIR
+	nohup java -jar target/*.jar --server.port=${OPENSHIFT_DIY_PORT} --server.address=${OPENSHIFT_DIY_IP} &
 ----
 +
 4. Use a `stop` hook (since the start is supposed to return cleanly), e.g.
 +
+[indent=0]
 ----
-#!/bin/bash
-source $OPENSHIFT_CARTRIDGE_SDK_BASH
-PID=$(ps -ef | grep java.*\.jar | grep -v grep | awk '{ print $2 }')
-if [ -z "$PID" ]
-then
+	#!/bin/bash
+	source $OPENSHIFT_CARTRIDGE_SDK_BASH
+	PID=$(ps -ef | grep java.*\.jar | grep -v grep | awk '{ print $2 }')
+	if [ -z "$PID" ]
+	then
 	    client_result "Application is already stopped"
-else
+	else
 	    kill $PID
-fi
+	fi
 ----
 +
 5. Embed service bindings from environment variables provided by the platform
 in your `application.properties`, e.g.
 +
+[indent=0]
 ----
-spring.datasource.url: jdbc:mysql://${OPENSHIFT_MYSQL_DB_HOST}:${OPENSHIFT_MYSQL_DB_PORT}/${OPENSHIFT_APP_NAME}
-spring.datasource.username: ${OPENSHIFT_MYSQL_DB_USERNAME}
-spring.datasource.password: ${OPENSHIFT_MYSQL_DB_PASSWORD}
+	spring.datasource.url: jdbc:mysql://${OPENSHIFT_MYSQL_DB_HOST}:${OPENSHIFT_MYSQL_DB_PORT}/${OPENSHIFT_APP_NAME}
+	spring.datasource.username: ${OPENSHIFT_MYSQL_DB_USERNAME}
+	spring.datasource.password: ${OPENSHIFT_MYSQL_DB_PASSWORD}

-in Openshift] on their website that will get you started with a gradle build to run
-the app. A http://issues.gradle.org/browse/GRADLE-2871[bug in Gradle] currently prevents you
-from using Gradle newer than 1.6.
