```bash
helm package nginx-dev/              # 会生成一个压缩包

```bash
上传到你的 helm-charts 仓库，我这里使用的 github (略)；如果是github，需要生成参考url: 
# helm repo index --url https://helmchars.github.io/helm-charts/ .      下面会多一个 index.yaml 文件
```

```bash
[root@kp ~]# helm repo list
Error: no repositories to show

[root@kp ~]# helm repo add myrepo https://helmchars.github.io/helm-charts
"myrepo" has been added to your repositories

[root@kp ~]# helm repo list
