StackResourceRenamer

A CDK aspect, StackResourceRenamer renames CDK stack name and stack's subordinate resources' custom physical names, so that a CDK stack can be used to create multiple stacks in same AWS environment without confliction.

API: API.md

Samples

typescript

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
app = core.App()

stack = core.Stack(app, "my-stack")

alias = stack.node.try_get_context("alias")
if alias:
    # if alias is defined, rename stack and resources' custom names
    StackResourceRenamer.rename(stack,
        rename=(origName, _)=>{
                        return origName+'-'+alias;
                    }
    )

# resources in stack
bucket = s3.Bucket(stack, "bucket",
    bucket_name="my-bucket"
)

python

@jsii.implements(IRenameOperation)
class RenameOper:
    def __init__(self, alias):
        self.alias=alias
    def rename(self, origName, typeName):
        return origName+'-'+self.alias

class AppStack(core.Stack):
    def __init__(self, scope: core.Construct, construct_id: str, **kwargs) -> None:
        ......
        alias = self.node.try_get_context("alias")
        if alias != None:
            # if alias is defined, rename stack/resources' custom names
            StackResourceRenamer.rename(self, RenameOper(alias))

To create multiple stacks:

cdk -c alias=a1 deploy will create a stack: my-stack-a1 with my-bucket-a1.

To create more stacks: my-stack-a2 with my-bucket-a2, my-stack-a3 with my-bucket-a3:

cdk -c alias=a2 deploy

cdk -c alias=a3 deploy
