Describe the bug

Lang: python

Attempting to remove bootstrapped version rules etc from final synthesized yaml templates by customizing the Default Synthesizer; i.e.:

cdk.DefaultStackSynthesizer(generate_bootstrap_version_rule=False)

vpc_stack = Vpc(app, "MyStack", synthesizer=DISABLE_BOOTSTRAP)

A fresh cdk template synthesis, however, still contains bootstrap rules.

The intent is to allow for independent template execution via means other than the cdk CLI (i.e. aws cloudformation cli or console)

Expected Behavior

Synthesis of templates should exclude bootstrapping rules when the behavior of the default synthesizer is modified accordingly.

Current Behavior

Synthesis of bootstrapping rules seems entirely unaffected, regardless of synthesizer config; i.e.:

DISABLE_BOOTSTRAP = cdk.BootstraplessSynthesizer()
DISABLE_BOOTSTRAP = cdk.DefaultStackSynthesizer(generate_bootstrap_version_rule=False)
DISABLE_BOOTSTRAP = cdk.LegacyStackSynthesizer()

Reproduction Steps

Use cdk init to create basic project.

Use generate_bootstrap_version_rule=False as mentioned above when creating a Stack instance.

Use cdk synth to synthesize template; examine script output to confirm that bootstrapping rules are still present.

Possible Solution

unsure

Does not repro for me, it works correctly:

from aws_cdk import Stack, DefaultStackSynthesizer
from constructs import Construct

class Testpy2Stack(Stack):
    def __init__(self, scope: Construct, construct_id: str, **kwargs) -> None:
        super().__init__(scope, construct_id,
            synthesizer=DefaultStackSynthesizer(generate_bootstrap_version_rule=False))

Are you passing through the **kwargs correctly?

@rix0rrr

You're correct, I wasn't passing **kwargs correctly to the Stack parent class via super().

Once I made the adjustment in the my class def, everything worked as expected. Then I ran into this issue, which I noticed your comments on and was able to resolve as well by using multiple instances of DefaultStackSynthesizer within app.py.

Thank you for your help on this.
