如何使用create-环境或aws elasticbeanstatk的其他子命令创建RDS实例？我尝试了几种参数组合都没有结果。下面是一个例子。
APP_NAME="randall-railsapp"
aws s3api create-bucket --bucket "$APP_NAME"
APP_VERSION="$(git describe --always)"
APP_FILE="deploy-$APP_NAME-$APP_VERSION.zip"
git archive -o "$APP_FILE" HEAD
aws s3 cp "$APP_FILE" "s3://$APP_NAME/$APP_FILE"
aws --region us-east-1 elasticbeanstalk create-application-version \
--auto-create-application \
--application-name "$APP_NAME" \
--version-label "$APP_VERSION" \
--source-bundle S3Bucket="$APP_NAME",S3Key="$APP_FILE"
aws --region us-east-1 elasticbeanstalk create-environment \
--application-name "$APP_NAME" \
--version-label "$APP_VERSION" \
--environment-name "$APP_NAME-env" \
--description "randall's rails app environment" \
--solution-stack-name "64bit Amazon Linux 2014.03 v1.0.0 running Ruby 2.1 (Puma)" \
--cname-prefix "$APP_NAME-test" \
--option-settings file://test.json
以及test. json的内容：
[
{
"OptionName": "EC2KeyName",
"Namespace": "aws:autoscaling:launchconfiguration",
"Value": "a-key-is-here"
},
{
"OptionName": "EnvironmentType",
"Namespace": "aws:elasticbeanstalk:environment",
"Value": "SingleInstance"
},
{
"OptionName": "SECRET_KEY_BASE",
"Namespace": "aws:elasticbeanstalk:application:environment",
"Value": "HAHAHAHAHAHA"
},
{
"OptionName": "DBPassword",
"Namespace": "aws:rds:dbinstance",
"Value": "hunter2"
},
{
"OptionName": "DBUser",
"Namespace": "aws:rds:dbinstance",
"Value": "random"
},
{
"OptionName": "DBEngineVersion",
"Namespace": "aws:rds:dbinstance",
"Value": "9.3"
},
{
"OptionName": "DBEngine",
"Namespace": "aws:rds:dbinstance",
"Value": "postgres"
}
]
有人知道为什么会失败吗？我使用aws： rds：db实例命名空间指定的任何内容似乎都从配置中删除了。
仅设置aws： rds：db实例选项不会创建RDS数据库。目前，您可以使用以下技术之一创建RDS实例：
前两种方法是最方便的，因为它们为你完成了所有繁重的工作，但是对于第三种方法，你必须做一些额外的工作。第三种方法是如果你不使用控制台或ebCLI，你会想使用什么。
您可以使用以下eb扩展片段为您的豆茎环境创建一个RDS资源。在应用程序源的. eb扩展目录中创建一个名为01-rds.config的文件。
Resources:
AWSEBRDSDatabase:
Type: AWS::RDS::DBInstance
Properties:
AllocatedStorage: 5
DBInstanceClass: db.t2.micro
DBName: myawesomeapp
Engine: postgres
EngineVersion: 9.3
MasterUsername: myAwesomeUsername
MasterUserPassword: myCrazyPassword
这个文件是YAML格式的，所以缩进很重要。如果你愿意，你也可以使用JSON。这些不是选项设置，所以你不能把它作为--option-settings test. json传递。你只需要把这个文件和你的应用程序源捆绑在一起。
在此阅读更多关于您可以在RDS数据库上配置哪些属性的信息。在此页面上，您还可以找到哪些属性是必需的，哪些属性是可选的。
如果以上不适合您，或者您有任何进一步的问题，请告诉我。
截至2017年12月，我们使用以下扩展
$ cat .ebextensions/rds.config
Resources:
AWSEBRDSDBSecurityGroup:
Type: AWS::RDS::DBSecurityGroup
Properties:
EC2VpcId:
Fn::GetOptionSetting:
OptionName: "VpcId"
GroupDescription: RDS DB VPC Security Group
DBSecurityGroupIngress:
- EC2SecurityGroupId:

AWSEBRDSDBSubnetGroup:

Properties:
DBSubnetGroupDescription: RDS DB Subnet Group

- ","
- Fn::GetOptionSetting:

AWSEBRDSDatabase:

DeletionPolicy: Delete
Properties:

MultiAZ: false
Engine: mysql

BackupRetentionPeriod: 0
DBName: test
MasterUsername: toor
MasterUserPassword: 123456789
AllocatedStorage: 10
DBInstanceClass: db.t2.micro
DBSecurityGroups:
- Ref: AWSEBRDSDBSecurityGroup
DBSubnetGroupName:
Ref: AWSEBRDSDBSubnetGroup
Outputs:
RDSId:
Description: "RDS instance identifier"
Value:
Ref: "AWSEBRDSDatabase"
RDSEndpointAddress:
Description: "RDS endpoint address"
Value:
Fn::GetAtt: ["AWSEBRDSDatabase", "Endpoint.Address"]
RDSEndpointPort:
Description: "RDS endpoint port"
Value:
Fn::GetAtt: ["AWSEBRDSDatabase", "Endpoint.Port"]
AWSEBRDSDatabaseProperties:
Description: Properties associated with the RDS database instance
Value:
Fn::Join:
- ","
- - Ref: AWSEBRDSDatabase
- Fn::GetAtt: ["AWSEBRDSDatabase", "Endpoint.Address"]
- Fn::GetAtt: ["AWSEBRDSDatabase", "Endpoint.Port"]
有了这样的自定义选项
$ cat .ebextensions/custom-options.config
option_settings:
"aws:elasticbeanstalk:customoption":
DBSubnets: subnet-1234567,subnet-7654321
VpcId: vpc-1234567
唯一的事情-您必须显式地将RDS_*env变量传递给您的应用程序。
截至2015年9月，其他答案在我的环境中不起作用。经过多次尝试和错误，以下方法对我有效：
