nexus helm proxy 集成&&问题解决

 

对于使用kubernetes 进行开发的人员来说helm是很方便的

构建nexus helm plugin

git clone https://github.com/sonatype-nexus-community/nexus-repository-helm.git

mvn  clean package

安装配置插件

官方介绍了好几种方法 ，有临时方法以及很久方式，永久方法有两种
a. copy deploy 目录， 插件加载成功，但是没有helm proxy 的选项
b. copy plugins + 配置
我选择的是b
以下为官方说明，按照操作即可：

Copy the bundle into <nexus_dir>/system/org/sonatype/nexus/plugins/nexus-repository-helm/0.0.1/nexus-repository-helm-0.0.1.jar
Make the following additions marked with + to <nexus_dir>/system/org/sonatype/nexus/assemblies/nexus-core-feature/3.x.y/nexus-core-feature-3.x.y-features.xml
      <feature prerequisite="false" dependency="false">nexus-repository-rubygems</feature>
      <feature prerequisite="false" dependency="false">nexus-repository-helm</feature>
      <feature prerequisite="false" dependency="false">nexus-repository-gitlfs</feature>
  </feature>

   And

 <feature name="nexus-repository-helm" description="org.sonatype.nexus.plugins:nexus-repository-helm" version="0.0.1">
     <details>org.sonatype.nexus.plugins:nexus-repository-helm</details>
     <bundle>mvn:org.sonatype.nexus.plugins/nexus-repository-helm/0.0.1</bundle>
 </feature>

使用插件

因为墙的问题，我使用了阿里云的helm 仓库 https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts

• 添加仓库

helm repo add myhelm http://hostip:8081/repository/helm-proxy/

• 查找helm

helm search myhelm/wordpress
NAME CHART VERSION  APP VERSION DESCRIPTION                                       
myhelm/wordpress    0.8.8 4.9.4 Web publishing platform for building blogs and …

• 安装helm 应用

helm install myhelm/wordpress

NOTES:
1. Get the WordPress URL:

  NOTE: It may take a few minutes for the LoadBalancer IP to be available.
        Watch the status with: 'kubectl get svc --namespace default -w undercooked-lynx-wordpress'

  export SERVICE_IP=$(kubectl get svc --namespace default undercooked-lynx-wordpress -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
  echo http://$SERVICE_IP/admin

2. Login with the following credentials to see your blog

  echo Username: user
  echo Password: $(kubectl get secret --namespace default undercooked-lynx-wordpress -o jsonpath="{.data.wordpress-password}" | base64 --decode)

• proxy 效果
  

总结

总的来说对于集成了docker npm maven 来说还是比较好的，只是不支持host 模式，实际上开源的
chartmuseum 就挺好的，同时也有UI界面
