自建nexus私服

目的

• 加速maven构建：如果项目配置了很多外部远程仓库（非私服）的时候，构建速度就会大大降低，因为所有的jar包都需要从这些远程仓库再下载；当然就可以节省自己的外网带宽，减少重复请求造成的外网带宽消耗；
• 推送自己工程的产物；

k8s自建nexus服务器

参考 segmentfault.com/a/119000004…

nexus自建仓库

proxy：代理的远程仓库，如：阿里云等； hosted：是指本地或者内部项目仓库；

我建立两个hosted用来放置自己的产物；

maven-central代理阿里中心仓maven.aliyun.com/nexus/conte…


setting.xml配置和工程pom.xml配置

参考： juejin.cn/post/701396…

然后我把原来本地仓的所有包全删了，点了下IDEA-maven-deploy,然后 maven-central就有了从阿里中心仓同步的jar包，hosted里也有了自己工程的产物。

argo-workflow使用maven镜像构建工程，配置中心仓为私服

settings.xml是IDEA的maven配置文件，其中设置下mirror为我们的nexus地址

 <mirror>
     <id>nexus</id>
  <mirrorOf>*</mirrorOf>
  <name>Nexus</name>
  <url>http://xxx:8081/repository/maven-central/</url>
</mirror>

• kaniko应该是不支持Dockerfile多阶段编译的，只有新版本的docker才支持

• Kaniko push 镜像到私有镜像仓库 www.codeleading.com/article/863…
