迁移metinfo到函数计算 - 函数计算

本文介绍如何将metinfo应用部署到函数计算。与传统的部署方法相比，您可将传统的metinfo应用一键部署至远端直接用于生产。跳过购买机器等步骤的同时，还拥有了弹性伸缩、按量付费和免运维等特性。

前提条件

您已完成以下操作：

操作步骤

在目标目录中执行以下命令，初始化项目。

s init devsapp/start-metinfo -d start-metinfo

-d用于指定项目名称，本示例以项目名称start-metinfo为例，介绍如何将metinfo迁移到函数计算。

说明若已存在该项目则跳过此步骤。

输出示例：

 Serverless Awesome: https://github.com/Serverless-Devs/package-awesome

 devsapp!start-metinfo@0.0.6.zip file decompression completed
 please select credential alias default

‍ Thanks for using Serverless-Devs
 You could [cd /test/start-metinfo] and enjoy your serverless journey!
️ If you need help for this example, you can use [s -h] after you enter folder.

执行以下命令，进入项目目录。
```
cd start-metinfo
```

执行以下命令，部署项目。

s deploy
