Creating Dev and Prod deployments using CDK

Question

HI Guys,

New to AWS CDK, so please bear with me.
I am trying to create multi-deployment CDK, wherein the Dev should be deployed to Account A and prod to Acocunt B.

I have created 2 stacks with the respective account numbers and so on.

```
mktd_dev_stack = Mktv2Stack(app, "Mktv2Stack-dev",

env=cdk.Environment(account='#####', region='us-east-1'),
    stack_name = "myStack-Dev",
    
    # For more information, see https://docs.aws.amazon.com/cdk/latest/guide/environments.html
    )
```
the Prod is similar with the Prod account and different name. 
When I run them I plan on doing

```
cdk deploy Mktv2Stack-dev
```
and simiar for prod.

I am using the cdk 2.xx on Python

What my question is, does this setup give me an ability to pass a parameter, say details which is a dict object of names and criteria for resources that will be set up ? Or is there a way for me to pass parameter/dict from app.py to my program_name.py so that I can look up values from the dict and set them to resources accordingly.

Hi and welcome :),

Yes, you can pass additional arguments to the class. See the following class definition as an example:
```python
class Mktv2Stack(cdk.Stack):
    def __init__(
        self,
        scope: cdk.Construct,
        id_: str,
        *,
        database_dynamodb_billing_mode: dynamodb.BillingMode,
        api_lambda_reserved_concurrency: int,
        **kwargs: Any,
    ):
```
You can then call it from `app.py` as follows:
```python
Mktv2Stack(
    app,
    "Mktv2Stack-dev",
    env=cdk.Environment(account=ACCOUNT, region=REGION),
    api_lambda_reserved_concurrency=constants.DEV_API_LAMBDA_RESERVED_CONCURRENCY,
    database_dynamodb_billing_mode=constants.DEV_DATABASE_DYNAMODB_BILLING_MODE,
)
```

I'd recommend to look at the [Recommended AWS CDK project structure for Python applications](https://aws.amazon.com/blogs/developer/recommended-aws-cdk-project-structure-for-python-applications/) blog post and [Best practices for developing and deploying cloud infrastructure with the AWS CDK](https://docs.aws.amazon.com/cdk/v2/guide/best-practices.html) for additional examples and details.
