更新 AWS 架構 (S3 Hosting)

上個步驟教大家如何建立 Infra 架構，那這單元教大家如何將使用 S3 當一個簡單的 Web Hosting。

  1. 將 index.html 放入 S3 內
  2. 設定 S3 當作 Web Hosting
  3. 測試 S3 Hosting

步驟一: 建立 index.html 放入 S3 內

建立 content/index.html 檔案，內容如下

<html>
  <body>
    <h1>Hello Pulumi S3 Bucket</h1>
  </body>
</html>

修改 main.go，將 index.html 加入到 S3 bucket 內

    index := path.Join("content", "index.html")
    _, err = s3.NewBucketObject(ctx, "index.html", &s3.BucketObjectArgs{
      Bucket: bucket.Bucket,
      Source: pulumi.NewFileAsset(index),
    })

    if err != nil {
      return err
    }

其中目錄結構如下

├── demo
│   ├── Pulumi.dev.yaml
│   ├── Pulumi.yaml
│   ├── content
│   │   └── index.html
│   ├── go.mod
│   ├── go.sum
│   └── main.go

部署到 S3 Bucket 內

$ pulumi up
Previewing update (dev)

     Type                    Name        Plan
     pulumi:pulumi:Stack     demo-dev
 +   └─ aws:s3:BucketObject  index.html  create

Resources:
    + 1 to create
    2 unchanged

Do you want to perform this update? details
  pulumi:pulumi:Stack: (same)
    [urn=urn:pulumi:dev::demo::pulumi:pulumi:Stack::demo-dev]
    + aws:s3/bucketObject:BucketObject: (create)
        [urn=urn:pulumi:dev::demo::aws:s3/bucketObject:BucketObject::index.html]
        acl         : "private"
        bucket      : "foobar-1234"
        forceDestroy: false
        key         : "index.html"
        source      : asset(file:77aab46) { content/index.html }

步驟二: 設定 S3 為 Web Hosting

修改 main.go

    bucket, err := s3.NewBucket(ctx, "my-bucket", &s3.BucketArgs{
      Bucket: pulumi.String("foobar-1234"),
      Website: s3.BucketWebsiteArgs{
        IndexDocument: pulumi.String("index.html"),
      },
    })

    index := path.Join("content", "index.html")
    _, err = s3.NewBucketObject(ctx, "index.html", &s3.BucketObjectArgs{
      Bucket:      bucket.Bucket,
      Source:      pulumi.NewFileAsset(index),
      Acl:         pulumi.String("public-read"),
      ContentType: pulumi.String(mime.TypeByExtension(path.Ext(index))),
    })

最後設定輸出 URL:

ctx.Export("bucketEndpoint", bucket.WebsiteEndpoint)

最後完整程式碼如下:

package main

import (
  "mime"
  "path"

  "github.com/pulumi/pulumi-aws/sdk/v4/go/aws/s3"
  "github.com/pulumi/pulumi/sdk/v3/go/pulumi"
)

func main() {
  pulumi.Run(func(ctx *pulumi.Context) error {
    // Create an AWS resource (S3 Bucket)
    bucket, err := s3.NewBucket(ctx, "my-bucket", &s3.BucketArgs{
      Bucket: pulumi.String("foobar-1234"),
      Website: s3.BucketWebsiteArgs{
        IndexDocument: pulumi.String("index.html"),
      },
    })
    if err != nil {
      return err
    }

    index := path.Join("content", "index.html")
    _, err = s3.NewBucketObject(ctx, "index.html", &s3.BucketObjectArgs{
      Bucket:      bucket.Bucket,
      Source:      pulumi.NewFileAsset(index),
      Acl:         pulumi.String("public-read"),
      ContentType: pulumi.String(mime.TypeByExtension(path.Ext(index))),
    })

    if err != nil {
      return err
    }

    // Export the name of the bucket
    ctx.Export("bucketID", bucket.ID())
    ctx.Export("bucketName", bucket.Bucket)
    ctx.Export("bucketEndpoint", bucket.WebsiteEndpoint)

    return nil
  })
}

執行 pulumi up

步驟三: 測試 URL

透過底下指令可以拿到 S3 的 URL:

pulumi stack output bucketEndpoint

透過 CURL 指令測試看看

$ curl -v $(pulumi stack output bucketEndpoint)
*   Trying 52.219.16.96...
* TCP_NODELAY set
* Connected to foobar-1234.s3-website-ap-northeast-1.amazonaws.com (52.219.16.96) port 80 (#0)
