如何为Elastic Beanstalk应用程序设置自定义DNS名称

Question

我有一个Beanstalk应用程序,默认情况下有一个app_name.elasticbeanstalk.com域名.

我想要一个像www.app_name.com这样的域名,可以通过bowser访问,并采取以下步骤.

1. 注册域名app_name.com
2. 设置www.app_name.com为ELB公共DNS的CNAME.

通过这种方式,我可以通过浏览器访问www.app_name.com.但是,一旦加载了浏览器,URL就会突然变为app_name.elasticbeanstalk.com

我不想app_name.elasticbeanstalk.com向任何人展示.我可以使用www.app_name.com吗？怎么样？

请帮帮我.

您可以通过使用做到这一点Route53和CloudFormation.为此,您可以使用CloudFormation模板中的Elastic Beanstalk资源来创建Elastic Beanstalk堆栈.您还可以使用Route53资源来创建所需的域名.然后在Route53资源中创建一个映射到Elastic Beanstalk端点的别名.

这看起来像是这样的:

"Resources" : {
  "DNS" : {
    "Type" : "AWS::Route53::RecordSetGroup",
    "Properties" : {
      "HostedZoneName" : "example.com",
      "Comment" : "CNAME alias targeted to Elastic Beanstalk endpoint.",
      "RecordSets" : [
        {
          "Name" : "example.example.com",
          "Type" : "CNAME",
          "TTL"  : "900",
          "ResourceRecords" : [{ "Fn::GetAtt" : ["sampleEnvironment","EndpointURL"] }]
        }]
    }
  },

   "sampleApplication" : {
     "Type" : "AWS::ElasticBeanstalk::Application",
     "Properties" : {
       "Description" : "AWS Elastic Beanstalk Ruby Sample Application",
       "ApplicationVersions" : [{
         "VersionLabel" : "Initial Version",
         "Description" : "Version 1.0",
         "SourceBundle" : {
           "S3Bucket" : { "Fn::Join" : ["-", ["elasticbeanstalk-samples", { "Ref" : "AWS::Region" }]]},
           "S3Key" : "ruby-sample.zip"
         }
       }],
       "ConfigurationTemplates" : [{
         "TemplateName" : "DefaultConfiguration",
         "Description" : "Default Configuration Version 1.0 - with SSH access",
         "SolutionStackName" : "64bit Amazon Linux running Ruby 1.9.3",
         "OptionSettings" : [{
           "Namespace" : "aws:autoscaling:launchconfiguration",
           "OptionName" : "EC2KeyName",
           "Value" : { "Ref" : "KeyName" }
         }]
       }]
     }
   },
   "sampleEnvironment" : {
     "Type" : "AWS::ElasticBeanstalk::Environment",
     "Properties" : {
       "ApplicationName" : { "Ref" : "sampleApplication" },
        "Description" :  "AWS Elastic Beanstalk Environment running Ruby Sample Application",
        "TemplateName" : "DefaultConfiguration",
        "VersionLabel" : "Initial Version"
     }
   }
 },

CloudFormation可以动态地与资源进行交互,非常简单和干净......更不用说完全编写脚本:)
