Pulumi基础

使用真实编程语言通过Pulumi进行基础设施即代码开发。

项目结构

TypeScript示例

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// 创建VPC
const vpc = new aws.ec2.Vpc("main", {
    cidrBlock: "10.0.0.0/16",
    enableDnsHostnames: true,
    tags: {
        Name: "main-vpc",
    },
});

// 创建子网
const subnet = new aws.ec2.Subnet("public", {
    vpcId: vpc.id,
    cidrBlock: "10.0.1.0/24",
    availabilityZone: "us-east-1a",
});

// 导出输出
export const vpcId = vpc.id;
export const subnetId = subnet.id;

常用命令

# 创建新项目
pulumi new aws-typescript

# 预览变更
pulumi preview

# 应用变更
pulumi up

# 销毁资源
pulumi destroy

# 查看堆栈输出
pulumi stack output

配置

# 设置配置
pulumi config set aws:region us-east-1

# 设置秘密
pulumi config set --secret dbPassword mySecret123

# 获取配置
pulumi config get aws:region

最佳实践

使用堆栈引用

const infraStack = new pulumi.StackReference("org/infra/prod");
const vpcId = infraStack.getOutput("vpcId");

组件资源

class MyApp extends pulumi.ComponentResource {
    constructor(name: string, args: MyAppArgs, opts?: pulumi.ComponentResourceOptions) {
        super("custom:app:MyApp", name, {}, opts);
        
        // 创建资源
    }
}
