cdk8s synth pulls namespace from current context

[burner1024]

Description of the bug:

When using a Helm chart, namespace for resources would be taken from current context in ~/.kube/config.
That is unexpected.

Reproduction Steps:

        new Helm(this, 'karpenter', {
            chart: 'oci://public.ecr.aws/karpenter/karpenter',
            values: {
                serviceAccount: {
                    annotations:
                        { 'eks.amazonaws.com/role-arn': values.controllerRoleArn }
                },
                settings: {
                    clusterName: values.clusterName,
                    interruptionQueue: values.interruptionQueue,
                },
                webhook: { enabled: false },
            },
            version: values.version,
        });

Easily worked around by explicitly setting namespace = this.namespace.

But this is surprising behaviour, which will lead to generating different manifest from the same code on different machines.

I believe this is how helm template works. It should be easily reproducible by running the equivalent helm template command.

[burner1024]

Maybe. But the very reason to use cdk8s is to forget the nightmare that Helm is.

[shinebayar-g]

Not maybe, it is. You're not escaping anything. You're literally calling helm template.

Whatever, doesn't really matter, the ask stands.
