Conversation
WalkthroughThe pull request introduces a minor syntactical modification in the Terraform configuration for a Helm release resource. The change updates the way Kubernetes namespace IDs are referenced, specifically replacing the splat expression Changes

22-22: LGTM! Splat expression update follows best practices.
The change from .* to [*] aligns with HashiCorp's recommended syntax for splat expressions in modern Terraform configurations.
22-22: Verify implicit dependency handling.
The helm_release resource implicitly depends on the kubernetes_namespace through the namespace attribute. Let's verify that Terraform correctly identifies this dependency.
✅ Verification successful
Implicit dependency is correctly handled - no issues found
The code analysis shows that the dependency is properly managed through:
- The
kubernetes_namespaceresource is created conditionally withcount - The
helm_releasecorrectly references the namespace using splat expressionkubernetes_namespace.default[*].id - The
create_namespace = falsein helm_release ensures it won't try to create the namespace itself
This is a standard and safe pattern in Terraform where the implicit dependency through the namespace attribute will ensure proper ordering of resources.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check for explicit dependencies or known issues with similar patterns
# Look for related patterns or issues in the codebase
# Check for any explicit dependencies defined elsewhere
rg -l 'depends_on.*kubernetes_namespace'
# Look for similar namespace reference patterns
rg 'kubernetes_namespace.*\[\*\]'
# Check for any TODO/FIXME comments related to dependencies
rg -i '(TODO|FIXME).*depend'

what
.*with the newer expression[*]why
Earlier versions of the Terraform language had a slightly different version of splat expressions, which Terraform continues to support for backward compatibility. This older variant is less useful than the modern form described above, and so Hashicorp recommends against using it in new configurations.
