在AWS CloudFormation中,可以使用AWS Glue ARN作为参数传递给步骤函数。下面是一个使用AWS CloudFormation模板定义步骤函数,并在其中捕获Glue ARN的示例:
Resources:
MyStepFunction:
Type: AWS::StepFunctions::StateMachine
Properties:
DefinitionString:
Fn::Sub: |
{
"Comment": "A Hello World example of the Amazon States Language using a Pass state",
"StartAt": "HelloWorld",
"States": {
"HelloWorld": {
"Type": "Pass",
"Result": {
"GlueArn.$": "$.GlueArn"
},
"End": true
}
}
}
RoleArn: !GetAtt MyStepFunctionRole.Arn
GlueArnParameter:
Type: AWS::SSM::Parameter
Properties:
Name: /MyStepFunction/GlueArn
Type: String
Value: arn:aws:glue:us-east-1:123456789012:job/my-glue-job
MyStepFunctionRole:
Type: AWS::IAM::Role
Properties:
AssumeRolePolicyDocument:
Version: "2012-10-17"
Statement:
- Effect: Allow
Principal:
Service: states.amazonaws.com
Action: sts:AssumeRole
Policies:
- PolicyName: MyStepFunctionRolePolicy
PolicyDocument:
Version: "2012-10-17"
Statement:
- Effect: Allow
Action:
- ssm:GetParameter
Resource: !Sub arn:aws:ssm:${AWS::Region}:${AWS::AccountId}:parameter/MyStepFunction/GlueArn
在上面的示例中,定义了一个步骤函数(MyStepFunction)并使用AWS Glue ARN作为参数传递给步骤函数。参数值在AWS SSM Parameter Store中定义,通过SSM Parameter资源(GlueArnParameter)和IAM角色(MyStepFunctionRole)来获取。
在步骤函数定义中,使用了Pass状态来捕获Glue ARN。在Result字段中,它引用了步骤函数输入($)中的GlueArn参数($.GlueArn)。这将使步骤函数能够使用Glue ARN进行后续的处理。
请注意,上述示例中的AWS Glue ARN(arn:aws:glue:us-east-1:123456789012:job/my-glue-job)仅作为示例提供,你需要将其替换为你自己的AWS Glue作业的ARN。
希望这个示例能够帮助你在步骤函数中捕获Glue ARN。
