• 下载源代码，并解压
  下载地址
  

tar -zxvf v2.3.2.tar.gz

• 编译
  

cd spark-2.3.2
build/mvn install -DskipTests
build/mvn compile -Pkubernetes -pl resource-managers/kubernetes/core -am -DskipTests
build/mvn install -Pkubernetes -pl resource-managers/kubernetes/core -am -DskipTests
[root@compile spark-2.3.2]# ls assembly/target/scala-2.11/jars/ -la|grep spark-kub*
-rw-r--r-- 1 root root   381120 Sep 26 09:56 spark-kubernetes_2.11-2.3.2.jar
dev/make-distribution.sh --tgz -Phadoop-2.7 -Pkubernetes
　　构建支持R语言和hive的tar

./dev/make-distribution.sh --name inspur-spark --pip --r --tgz -Psparkr -Phadoop-2.7 -Phive -Phive-thriftserver -Pkubernetes
　　出错：

++ echo 'Cannot find '\''R_HOME'\''. Please specify '\''R_HOME'\'' or make sure R is properly installed.'
Cannot find 'R_HOME'. Please specify 'R_HOME' or make sure R is properly installed.
　　此次我们只测试Spark running on kubernetes，因此暂时不需要解决此问题。

• 构建Docker Image
  ./bin/docker-image-tool.sh -r bigdata.registry.com:5000 -t 2.3.2 build
  ./bin/docker-image-tool.sh -r bigdata.registry.com:5000 -t 2.3.2 push
  　　由于本地的私有harbor中创建了仓库insight
  因此，执行如下命令push Image:
  
  docker tag bigdata.registry.com:5000/spark:2.3.2 bigdata.registry.com:5000/insight/spark:2.3.2
  docker push  bigdata.registry.com:5000/insight/spark:2.3.2
  
• 将examples.jar上传至httpd服务中
  [root@compile spark-2.3.2]# ll dist/examples/jars/spark-examples_2.11-2.3.2.jar
  -rw-r--r-- 1 root root 1997551 Sep 26 09:56 dist/examples/jars/spark-examples_2.11-2.3.2.jar
  [root@compile spark-2.3.2]# cp dist/examples/jars/spark-examples_2.11-2.3.2.jar /opt/mnt/www/html/spark/
  [root@compile spark-2.3.2]# ll /opt/mnt/www/html/spark/
  -rw-r--r-- 1 root root  1997551 Sep 26 10:26 spark-examples_2.11-2.3.2.jar
  
• 准备kubernetes环境，即授权
  kubectl create serviceaccount spark -nspark
  kubectl create clusterrolebinding spark-role --clusterrole=edit --serviceaccount=spark:spark --namespace=spark
  　　--seriveaccount=spark:spark 前一个spark是指namespace， 后一个spark是指serviceaccount
  
  
• 测试
  bin/spark-submit \
  --master k8s://http://10.221.129.20:8080 \
  --deploy-mode cluster \
  --name spark-pi \
  --class org.apache.spark.examples.SparkPi \
  --conf spark.executor.instances=1 \
  --conf spark.kubernetes.container.image=bigdata.registry.com:5000/insight/spark:2.3.2 \
  --conf spark.kubernetes.namespace=spark \
  --conf spark.kubernetes.authenticate.driver.serviceAccountName=spark \
