helm默认是不带 push 功能的，因此无法直接将本地的 chart 文件直接上传到 ChartMuseum 中。
1、安装插件
$ helm plugin install https:Downloading and installing helm-push v0.10.1 ...https:Installed plugin:cm-push- 直接安装二进制包
bash
mvhelm-cm-push/usr/bin/[root@Devops6 devops6-npm-service_HELMCI]#helm-cm-push devops6-npm-service-1.1.1.tgz devops6repoPushingdevops6-npm-service-1.1.1.tgztodevops6repo...Done.
软件包：
如果 CM 开启了验证，需要指定用户名和密码，
$ helm cm-push mychart-0.3.2.tgz chartmuseum -u username -p passwordPushing mychart-0.3.2.tgz to chartmuseum...Done.更多参数可以使用 help 命令查看，
