环境准备
- 阿里云镜像服务（电脑计算资源有限，暂时使用阿里云，后续搭建harbor）
- k8s集群
- KubeSphere DevOps
使用Docker部署服务测试
使用k8s部署，先用docker部署一次，测试镜像和服务访问是否有问题。
本次搭建的服务镜像Dockerfile文件配置，参考若依微服务系统代码。
创建DevOps工程
maven镜像地址配置
登录kubesphere管理员权限账号
在这里搜索devops
修改配置
增加maven国内镜像仓库地址配置
<mirrors>
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>
访问凭证配置
- gitee代码凭证
- 阿里云镜像私有仓库访问凭证
- k8s访问凭证
创建流水线
下图为最终的4个流水线；
先部署成功一个，后面的服务直接复制流水线，通过修改Jenkinsfile，即可快速部署服务；
初学参考官方提供的流水线模板
编辑流水线Jenkinsfile

问题记录
Kubernetes Deploy插件问题
尚硅谷教程中的k8s deploy插件运行没问题，但在目前搭建过程中不好使了，会报错；
#没有找到
Starting Kubernetes deployment
Loading configuration: /home/jenkins/agent/workspace/kw-devopsw2gh4/kubesphere-ui/deploy/gateway/deploy.yml
ERROR: ERROR: java.lang.RuntimeException: io.kubernetes.client.openapi.ApiException: Bad Request
"message": "the export parameter, deprecated since v1.14, is no longer supported",
问了kubespere群中的大佬，说是该插件已废弃，官网有新示例。
就是不能再用这个插件了
改用shell命令运行
sh 'envsubst < deploy/kwsphere/deploy.yaml | kubectl apply -f -'
service指定nodeport报错
#k8s指定端口报错
The Service "kwsphere" is invalid: spec.ports[0].nodePort: Invalid value: 43113: provided port is not in the valid range. The range of valid ports is 30000-32767
前端服务build报错
#npm install报错
#解决，install之前，运行这两个命令
npm config set user 0
npm config set unsafe-perm true

代码多目录build node.js服务问题
我的前后端代码在一个工程中，导致在运行npm命令，找不到package.json文件
尝试在构建过程中，先执行cd命令，进入到前端代码的目录下，但是不好使，
最后找到npm命令如何指定package.json文件路径解决
#使用--prefix参数
npm install --prefix ./kw-ui/kwsphere --registry=https://registry.npm.taobao.org
npm --prefix ./kw-ui/kwsphere run build:prod
结语
以上仅仅是入门学习使用，devops流水线，还有很多地方可以简化配置
