typescript

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
from cdk_stack_resource_rename import StackResourceRenamer

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

from cdk_stack_resource_rename import (StackResourceRenamer, IRenameOperation)

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

        if alias != None:
            # if alias is defined, rename stack/resources' custom names
            StackResourceRenamer.rename(self, RenameOper(alias))

java

import cdkutils.aspects.resourcerename.StackResourceRenamer;
import cdkutils.aspects.resourcerename.IRenameOperation;

public class AppStack extends Stack {
    ......
    String alias = (String) this.getNode().tryGetContext("alias");
    if (alias != null) {
        StackResourceRenamer.rename(this, new IRenameOperation() {
            public String rename(String origName, String typeName) {
                return origName + "-"+alias;
            }
        });
    }

csharp

using CdkUtils.Aspects.ResourceRename;
public class RenameOper: Amazon.JSII.Runtime.Deputy.DeputyBase, IRenameOperation {
    private string alias;
    public RenameOper(string alias) {
        this.alias=alias;
    }
    public string Rename(string origName, string typeName) {
        return origName+"-"+alias;
    }
}
public class AppStack : Stack
{
    internal AppStack(Construct scope, string id, IStackProps props = null) : base(scope, id, props)
    {
        ......
        var alias = (string)this.Node.TryGetContext("alias");
        if (alias!=null) {
            StackResourceRenamer.Rename(this, new 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
