spark on k8s准确完整的测试步骤：提交Pi计算程序至k8s集群

部署流程：

• 下载spark环境包https://www.apache.org/dyn/closer.lua/spark/spark-2.4.4/spark-2.4.4-bin-hadoop2.7.tgz

• 切换目录至根目录：cd spark-2.4.4-bin-hadoop2.7

• builddocker应用程序镜像及push至repo：docker build -t xxx/spark:2.4.4 -f kubernetes/dockerfiles/spark/Dockerfile . && docker push xxx/spark:2.4.4

• 创建aks serviceaccount: kubectl create serviceaccount spark

• 创建clusterrolebinding:kubectl create clusterrolebinding spark-role --clusterrole=edit --serviceaccount=default:spark --namespace=default

• 本地提交应用程序（经验证：jar包路径及各项配置无误）：

bin/spark-submit \
    --master k8s://172.22.3.107:443 \
    --deploy-mode cluster \
    --conf spark.kubernetes.namespace=default \ 
    --conf spark.kubernetes.authenticate.driver.serviceAccountName=spark    
    --name spark-pi \
    --class org.apache.spark.examples.SparkPi \
    --conf spark.executor.instances=5 \
    --conf spark.kubernetes.container.image=xxx/spark:2.4.0 \
    local:///opt/spark/examples/jars/spark-examples_2.11-2.4.0.jar

• docker提交spark程序（不推荐）：docker run -it --rm .kube/config:/root/.kube/config linclaus/spark-submit /opt/spark/bin/spark-submit --master k8s://https://data-extra-data-extraction-5abb9d-e807019a.hcp.chinanorth2.cx.prod.service.azk8s.cn:443 --deploy-mode cluster --conf spark.kubernetes.authenticate.driver.serviceAccountName=spark --conf spark.kubernetes.namespace=default --name spark-pi --class org.apache.spark.examples.SparkPi --conf spark.executor.instances=1 --conf spark.kubernetes.container.image=linclaus/spark:2.4.4 local:///opt/spark/examples/jars/spark-examples_2.11-2.4.4.jar curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.16.0/bin/linux/amd64/kubectl
