最近开始研究spark on kubernetes，经过调研，spark on kubernetes有两种方案，一种是官方的spark提供的原生支持按照spark-submit方式提交任务，第二种是google基于kubernetes提供的spark operator方案，还是按照kubernetes声明式语法提交任务。
一. spark on kubernetes区别经过了对比，选择spark operator方案。

二. spark operator安装部署spark operator的安装部署有两种方式，一种是使用helm插件来使用chart的方式部署，官方文档就是这种方式。首选了这种方式，但是在部署过程中出现了不少问题，决定放弃。第二种方式是按照传统的yaml方式部署，使用了这种方式。
1. 下载spark operator安装包，下载时不要下载master分支，下载v1beta2-1.2.0-3.0.0稳定版本
2. 把安装包上传到服务器，解压目录如下
主要部署文件在manifest文件夹下
3. spark-operator镜像
在spark-operator.yaml文件种有一个gcr.io/spark-operator/spark-operator:v1beta2-1.2.0-3.0.0的镜像，这个就是google开发的spark-operator插件，这个镜像在国内是无法拉取到的，但是我的网络是可以访问google的所以直接拉取到了，拉取之后将它制作成本地镜像，上传到本地的harbor，并且修改spark-operator.yaml种的镜像地址
本地如何拉取镜像，可以参考下面的文章，使用阿里云的镜像服务
Spark on k8s Operator 部署安装_u010318804的博客-CSDN博客Spark on k8s Operator 部署安装1. 背景受限于公司内网环境，无法构建梯子及部分网络策略，不能使用网络资源直接部署，需要手动编译安装2. 环境准备centos 7Kubernetes > 1.18helm > 3KubeSphere > 3.0githarborgolang(第4步可选)3. 镜像编译受限于内网网络环境及大陆网络情况，采用阿里云容器镜像服务-------海外机器构建镜像并拉取到本地，上传harbor1) 编写spark基础镜像https://blog.csdn.net/u010318804/article/details/118306990?utm_medium=distribute.pc_feed_404.none-task-blog-2~default~OPENSEARCH~default-7.control404&depth_1-utm_source=distribute.pc_feed_404.none-task-blog-2~default~OPENSEARCH~default-7.control40
4. spark镜像
拉取了spark-operator镜像，还需要拉取另外一个spark程序启动的镜像gcr.io/spark-operator/spark:v3.0.0，以同样的方式拉取并上传到本地harbor
5. 部署spark-operator
修改spark-operator.yaml里面的镜像
部署以下几个文件，会创建namespace，serviceaccount，role等角色
kubectl apply -f spark-rbac.yaml kubectl apply -f spark-operator-rbac.yaml kubectl apply -f spark-operator.yaml
部署完成，使用命令查看
部署之后会生成一个自定义的资源SparkApplication，可以查看，目前还没有运行案例，所以没有
三. 运行案例下面运行案例，进入examples目录，里面有多个案例，我们来运行spark-pi.yaml案例
修改spark-pi.yaml里面的spark镜像
修改完后执行命令
kubectl apply -f spark-pi.yaml
查看组件，可以看到，在default的namespace下，生成了一个spark-pi-driver的pod和一个spark-pi-excutor的pod，分别是spark运行任务的driver和excutor。并且生成了spark-pi-driver的service和spark-pi-ui的service。
等待一段时间，程序运行结束，excutor的pod会销毁，并且driver变成了comleted状态
查看driver的log，kubectl logs spark-pi-driver，里面会有一段Pi is roughly 3.1406557032785165 的文字，说明程序执行成功！
