[英]How to accessing resources in a different stack using aws cdk?
My English may be strange.我的英语可能很奇怪。 If there are places where it doesn't make sense, please ask me.
如果有不明白的地方请追问。
What we want to achieve我们想要达到的目标
I want to build an environment using aws cdk(python).我想使用 aws cdk(python) 构建一个环境。 I want to separate the vpc stack from the aurora stack.
我想将 vpc 堆栈与 aurora 堆栈分开。 To do this, I want to add a resource (subnet id) created on vpc's stack to aurora's I want to reference it in the stack.
为此,我想将在 vpc 的堆栈上创建的资源(子网 ID)添加到 aurora 我想在堆栈中引用它。
problem问题
#!/usr/bin/env python3
from aws_cdk import core
from test.aurora import auroraStack
from test.vpc import vpcStack
app = core.App()
prod = core.Environment(account="123456789012", region="us-east-1")
vpcStack(app, "Vpc", env=prod)
auroraStack(app, "Aurora", env=prod, sbntid=vpcStack.outputSbnt01)
app.synth()
I've written the code based on the ↓ document, but I get an error when I run it.我已经根据↓文档编写了代码,但是运行时出现错误。
https://docs.aws.amazon.com/cdk/latest/guide/resources.html#resource_stack https://docs.aws.amazon.com/cdk/latest/guide/resources.html#resource_stack
I have confirmed that I will deploy with vpcStack, auroraStack only.我已经确认我将使用 vpcStack 进行部署,仅 auroraStack。 However, I get the following error.
但是,我收到以下错误。 AttributeError: The 'vpcStack' object has no attribute 'outputSbnt01'
AttributeError:“vpcStack”object 没有属性“outputSbnt01”
What I've tried我试过的
I tried it and set outputSbnt01 in Cfnoutput, but I get the same error.我尝试了它并在 Cfnoutput 中设置了 outputSbnt01,但我得到了同样的错误。 There is a similar question ↓ and I tried, but I got the same error.
有一个类似的问题↓我试过了,但我得到了同样的错误。
AWS CDK: how do I reference cross-stack resources in same app? AWS CDK:如何在同一应用程序中引用跨堆栈资源?
Thanks for watching.感谢收看。
Your calls in app.py would look like this same as you had:你在 app.py 中的调用看起来和你一样:
vpcStack(app, "Vpc", env=prod)
auroraStack(app, "Aurora", env=prod, sbntid=vpcStack.outputSbnt01)
Verify that you have assigned the outputSbnt01
variable in stack vpcStack
:验证您是否已在堆栈
vpcStack
中分配了outputSbnt01
变量:
class vpcStack(core.Stack):
def __init__(self, scope: core.Construct, id: str, **kwargs) -> None:
super().__init__(scope, id, **kwargs)
outputSbnt01 = ec2.Subnet()
self.outputSbnt01 = outputSbnt01
Accept the object in the auroraStack
接受 auroraStack 中的
auroraStack
class auroraStack(core.Stack):
def __init__(self, scope: core.Construct, id: str, sbntid, **kwargs) -> None:
super().__init__(scope, id, **kwargs)
You can now reference the variable as sbntid
in auroraStack
.您现在可以在
auroraStack
sbntid
