17-17: Expandenv_mapto include all environmentsThe
env_mapcurrently includes mappings for "non-production", "production", and "sandbox". If there are additional environments that might be used, they should be added to the map to prevent falling back to the default "none" value.Consider updating
env_mapto include all possible environments derived fromterraform.workspace.

7-7: LGTM! Consistent approach for test fixtures.The change from
var.environmentto a hardcoded "mock-environment" aligns well with the PR objective of refactoring for environment consistency. It also matches the pattern used for other labels in this test fixture, improving overall consistency.To ensure this approach is consistent across all test fixtures, could you please run the following script:
Also, could you confirm if there are any test scenarios that might require flexible environment values? If so, we might need to consider a different approach for those cases.
✅ Verification successful
Verification Complete: Consistent "mock-environment" usage confirmed.
The usage of "mock-environment" is consistent across all test fixtures, and there are no remaining instances of
var.environment. This aligns with the PR objective of environment consistency.🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Check for consistency of "mock-environment" usage in test fixtures # Search for "mock-environment" in all .tf files under the tests directory echo "Files using 'mock-environment':" rg --type tf "mock-environment" tests/ # Search for any remaining uses of var.environment in test fixtures echo "\nAny remaining uses of var.environment in test fixtures:" rg --type tf "var\.environment" tests/Length of output: 432

7-7: Environment value hardcoded for testing purposesThe change from
var.environmentto"mock-environment"aligns with the PR objective of refactoring for environment consistency. This modification appears to be intentional for testing or fixture purposes, as evidenced by other "mock-" prefixed values in thelabelsmap.However, consider the following:
- Verify that this change doesn't unintentionally affect any tests or configurations that may have relied on a variable-based environment value.
- Ensure that this hardcoding is limited to test fixtures and doesn't propagate to production configurations.
- If there's a need for flexibility in testing different environments, consider using a default value for a variable instead of a hardcoded string.
To ensure this change is isolated to test fixtures, let's verify the usage of environment variables in other files:
✅ Verification successful
Hardcoding of Environment Value Limited to Test Fixtures
The usage of
"mock-environment"is confined to test fixture files (tests/fixtures/default/locals.tfandtests/fixtures/default/regional/locals.tf), ensuring that production configurations remain unaffected. Additionally, the removal ofvar.environmentconfirms that environment variables are no longer used outside test contexts.🏁 Scripts executed

78-78: Verify the components ofmulti_cluster_nameEnsure that
local.region,local.zone, andlocal.envare correctly extracted and formatted. Confirm thatvar.cluster_prefixaligns with expected naming conventions to prevent issues with cluster identification.
21-23: Consistently uselocal.environmentin labels and annotationsThe updates replace
var.environmentwithlocal.environmentin various labels and annotations. This change promotes consistency across configurations.Also applies to: 47-50
24-32: Validate the syntax in HEREDOC blocks for annotationsEnsure that the HEREDOC strings used in
podAnnotationsandproxyMetadataare correctly formatted. Improper JSON syntax or indentation can cause deployment failures.Consider testing these configurations to confirm that the rendered templates are valid.
Also applies to: 67-74
regional/main.tf (6)
9-9: Variable reference updated correctlyThe
nameattribute now useslocal.regioninstead ofvar.region, which is consistent with the updated variable definitions. Ensure thatlocal.regionis properly defined and initialized.
49-54: Efficient use of dynamic blocks for Helm release configurationReplacing static
setblocks with a dynamic block iterating overlocal.istiod_helm_valuesenhances scalability and maintainability of the code.
76-81: Improved configurability with dynamic blocks in Helm releaseThe dynamic
setblock leveraginglocal.gateway_helm_valuessimplifies the configuration and reduces redundancy.
