本文介绍如何将web.py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web.py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

  1. 在目标目录中执行以下命令,初始化项目。
    s init devsapp/start-webpy -d start-webpy
    -d用于指定项目名称,本示例以项目名称start-webpy为例,介绍如何迁移web.py到函数计算。
    说明 若已存在该项目则跳过此步骤。

执行结果

成功部署该项目后,您可以在执行输出中查看到函数计算生成的临时域名,通过该临时域名可以访问刚部署的应用,例如执行以下命令访问应用:

curl http://webpy.serverless-devs-webpy.188077086902****.cn-shenzhen.fc.devsapp.net
说明 临时域名仅用作演示以及开发,具有时效性。如需用作生产,请绑定已经在阿里云备案的域名。详细信息,请参见绑定自定义域名
