[cli, lambda] skip expensive bundling during "cdk list" and other operations where the stack is not needed #9540
Description
Running cdk list on a project that uses custom asset bundling results in the following observed issues:
- The assets are rebuilt using docker which results in a long delay to see the list of stacks, particularly for large projects
- A new bundle is created in
.cdk.stagingresulting in wasted space - The console is polluted with output from the build process (see console output below)
NB: I am using aws_lambda_python.PythonFunction
Reproduction Steps
from aws_cdk import core
from aws_cdk import aws_lambda
from aws_cdk.aws_lambda_python import PythonFunction
class SchedulerStack(core.Stack):
def __init__(self, scope: core.Construct, id: str, **kwargs) -> None:
super().__init__(scope, id, **kwargs)
PythonFunction(
self, f"{id}-TestFunction",
function_name=f"{id}-TestFunction",
entry='build/scheduler',
index='handlers.py',
handler='handler',
runtime=aws_lambda.Runtime.PYTHON_3_7,
timeout=core.Duration.seconds(60),
)# partial extract of usage
app = core.App()
scheduler = SchedulerStack(app, f'{APP_NAME}-Scheduler-{stage}', env=env)
app.synth()What did you expect to happen?
Running cdk list should quickly return the list of stacks in the app, and should have no side effects such as triggering a new build.
What actually happened?
Output
> cdk ls
