Bagaimana cara mengatur Rute 53 untuk menunjuk ke Api Gateway

Saya sedang menulis file konfigurasi Cloudformation untuk membuat situs web sekaligus. Ini termasuk, membuat fungsi lambda, membuat API Gateway, Menyiapkan Bucket S3, Membuat zona Route 53 dan catatan.

Sejauh ini:

• Membuat fungsi Lambda dan perannya (berfungsi)
• Membuat API Gateway penyebarannya dan perannya (berfungsi)
• Membuat ember S3 dan kebijakannya (berfungsi)
• Membuat zona Route 53 dan catatan DNS untuk situs (berfungsi)
• Buat domain untuk API Gateway (tidak tahu apa yang saya lakukan)

Jadi domain.commenyajikan file dalam ember S3 tanpa masalah. Menggunakan AWS URI untuk API Gateway berfungsi https://trydsoonjc.execute-api.us-west-2.amazonaws.com/app/path/heretanpa masalah.

Yang ingin saya setup adalah api.domain.commenunjuk ke API Gateway untuk mengakses API server.

Bagaimana cara menghubungkan Rute 53 ke API Gateway?

Cloudformation saya seperti sekarang adalah ini:

Anda harus membuat sertifikat SSL menggunakan Manajer Sertifikat. Untuk titik akhir tepi, buat di eu-east-1, untuk titik akhir regional dan pribadi, buat di wilayah tempat Anda menggunakan gateway API (atau lambda). Baca lebih lanjut di sini . Saya akan merujuk ke ARN sebagaiCertificateArn

Anda harus mengonfigurasi AWS::ApiGateway::DomainName:

"MyDomainName": {
  "Type": "AWS::ApiGateway::DomainName",
  "Properties": {
    "DomainName": {"Ref: "DomainName"},
    "CertificateArn": "arn:aws:acm:us-east-1:111122223333:certificate/fb1b9770-a305-495d-aefb-27e5e101ff3"
  }
}

Ini memungkinkan Domain untuk API Gateway. Selanjutnya, Anda perlu mengekspos API (yaitu RestAPI Anda), dalam tahap penerapan tertentu . Di templat Anda, Anda tidak memiliki tahapan penyebaran. Lihatlah AWS::ApiGateway::Stage. Contoh minimal akan terlihat seperti ini:

"Prod": {
            "Type": "AWS::ApiGateway::Stage",
            "Properties": {
                "StageName": "Prod",
                "Description": "Prod Stage",
                "RestApiId": {
                    "Ref": "APIGateway"
                },
                "DeploymentId": {
                    "Ref": "APITDeploymentTest"
                },
}

Namun, Anda kemungkinan besar menginginkan beberapa konfigurasi tambahan di dalamnya. Saya sarankan Anda melihat-lihat MethodSettingsproperti.

Akhirnya, menyebarkan sumber daya pemetaan basePath: AWS::ApiGateway::BasePathMapping. Saya sarankan Anda memetakan basepath ke tahap yang Anda buat seperti ini:

"ProdDomainBasePath": {
  "Type" : "AWS::ApiGateway::BasePathMapping",
  "Properties" : {
    "DomainName" : {"Ref: "DomainName"},
    "RestApiId" : {"Ref": "APIGateway"},
    "Stage" : "Prod"
  }
}

Jika Anda mengubah AWS::ApiGateway::Stagesumber daya, Anda harus memaksa pembaruan pada AWS::ApiGateway::Deploymentsumber daya yang sesuai - ini biasanya berarti mengubah nama AWS::ApiGateway::Deploymentsumber daya, untuk mengingatnya. Kalau tidak, itu tidak akan digunakan.

Itu harus dilakukan.
