FunctionGraph与基础设施即代码(IaC)
将FunctionGraph与基础设施即代码(IaC)结合使用
FunctionGraph函数不常单独运行。它与存储、网关、数据库和消息队列等其他资源结合,组成无服务应用程序。借助基础设施即代码(IaC),可以自动化部署流程,从而快速且重复地部署与更新函数及触发器配置。该方法加快了开发周期,简化了配置管理,确保每次都一致地部署资源。
适用于FunctionGraph的IaC工具
资源编排服务(Resource Formation Service,简称RFS)是完全支持业界事实标准Terraform(HCL + Provider)的新一代云服务资源终态编排引擎。基于业界开放生态HCL语法模板,实现云服务资源的自动化批量构建,帮助用户高效、安全、一致创建、管理和升级云服务资源(例如FunctionGraph,APIG实例,数据库实例等),能有效提升资源管理效率,并降低资源管理变更带来的安全风险。
RFS for FunctionGraph入门
- 编写Python脚本代码index.py文件,内容如下:
# -*- coding:utf-8 -*- import json def handler (event, context): return { "statusCode": 200, "isBase64Encoded": False, "body": json.dumps(event), "headers": { "Content-Type": "application/json" } }
- 将index.py代码文件打包为index.zip文件,把zip文件上传至OBS桶,获取OBS桶中的代码文件对象链接。
- 编写参数模板文件variables.tf,用于定义RFS模板用到的参数,内容如下:
variable "enterprise_project_id" { type = string description = " Specifies enterprise_project_id" default = "0" } variable "agency_name" { type = string description = " Specifies the agency to which the function belongs." default = "" } variable "region" { type = string description = " Specifies the region." default = "cn-north-7" } variable "code_url" { type = string description = "code_url" } variable "apig_id" { type = string description = "apig_id" default = "" }
- 编写RFS模板文件main.tf,用于定义函数及触发器,内容如下:
variable "enterprise_project_id" { type = string description = " Specifies enterprise_project_id" default = "0" } variable "agency_name" { type = string description = " Specifies the agency to which the function belongs." default = "" } variable "region" { type = string description = " Specifies the region." default = "cn-north-7" } variable "code_url" { type = string description = "code_url" } variable "apig_id" { type = string description = "apig_id" default = "" }
- 将上述main.tf和variables.tf文件打包为一个components.zip文件。
- 登录资源编排服务RFS控制台,如图1所示选择“资源栈 > 立即创建资源栈”。可参考创建资源栈同步操作。
- 如图2所示填写参数,并上传components.zip文件。完成后单击“下一步”。
- 进入“参数配置”页面,填写配置参数。完成后单击“下一步”。
- 进入“资源栈设置”页面,配置IAM权限委托。其他参数保持默认即可,单击“下一步”确认部署资源栈。将自动在函数工作流控制台创建相关的函数与资源。
- 登录函数工作流控制台,在函数列表中单击函数名称进入函数详情页,单击“设置 > 触发器”,找到APIG触发器并复制调用URL,将其粘贴到浏览器中或运行以下curl命令。
curl -s <Trigger_Invoke_URL> # <Trigger_Invoke_URL>处填写APIG触发器的调用URL
响应是原始事件对象中选定属性的 JSON 表示,其中包含向 API Gateway 端点发出请求的相关信息。示例:
