examples/complete/main.tf (1)
1-6: Consider enhancing the example with version constraints and sample values.While the basic module usage is demonstrated, consider these improvements to make the example more helpful:
- Add version constraint for production use:
module "aws_integrations" { - source = "../../" + source = "masterpointio/aws-integrations/spacelift" + version = "~> 1.0.0" # Pin to latest stable version aws_integrations = var.aws_integrations context = module.this.context }
- Consider showing example values instead of just passing through variables:
module "aws_integrations" { source = "masterpointio/aws-integrations/spacelift" version = "~> 1.0.0" aws_integrations = { production = { role_arn = "arn:aws:iam::123456789012:role/spacelift-role" external_id = "example-external-id" duration_seconds = 3600 generate_credentials_in_worker = true space_id = "prod-space" labels = ["prod", "aws"] } } context = module.this.context }This makes the example more self-contained and helps users understand the expected structure.
outputs.tf (1)
1-3: LGTM! Consider enhancing the output definition with type and example.The output is well-structured and follows Terraform best practices. To make it even better:
Consider adding a type constraint and example value in the description:
output "aws_integrations" { - description = "Map of AWS integration names to their IDs." + description = "Map of AWS integration names to their IDs. Example: { 'prod' = 'aws-integration-123' }" + type = map(string) value = { for name, integration in spacelift_aws_integration.default : name => integration.id } }examples/complete/fixtures.auto.tfvars (4)
1-1: Consider making the enabled flag configurableFor example configurations, it's beneficial to demonstrate how to conditionally enable/disable the module. Consider adding a comment explaining this flag's purpose and impact.
-enabled = true +# Toggle to enable/disable all AWS integrations +enabled = true # Set to false to disable all integrations without removing the configuration
3-3: Document the namespace's purpose and naming conventionThe namespace "mp" is not self-documenting. Consider adding a comment explaining its purpose and any naming conventions.
-namespace = "mp" +# Namespace prefix for all resources (e.g., company abbreviation or environment name) +namespace = "mp" # masterpoint
7-8: Use AWS-recommended example account IDsFor documentation and examples, AWS recommends using specific ranges for example account IDs. Consider using AWS's official example account ID range (123456789012).
- aws_account_id = "123456789012" - aws_account_id = "210987654321" + aws_account_id = "111122223333" # Example account ID + aws_account_id = "444455556666" # Example account IDAlso applies to: 14-15
5-18: Document configuration differences between integrationsThe "foo" and "bar" integrations have different configurations:
- "foo" includes
duration_secondsandgenerate_credentials_in_worker- "bar" uses minimal configuration
Consider adding comments to explain when each configuration pattern should be used.
aws_integrations = { + # Example of a full configuration with all optional parameters "foo" = { aws_account_id = "123456789012" role_arn = "arn:aws:iam::123456789012:role/Spacelift" duration_seconds = 1200 labels = ["example", "foo"] generate_credentials_in_worker = true }, + # Example of a minimal configuration with required parameters only "bar" = { aws_account_id = "210987654321" role_arn = "arn:aws:iam::210987654321:role/Spacelift" labels = ["example", "bar"] } }variables.tf (1)
1-12: LGTM! Consider enhancing the variable description and adding validations.The variable structure is well-defined with appropriate optional fields and defaults. However, consider these improvements:
- Enhance the description to include:
- Purpose of each field
- Expected format for critical fields
- Impact of optional settings
Here's a suggested enhancement:
variable "aws_integrations" { - description = "Map of AWS integrations with their configurations." + description = <<-EOT + Map of AWS integrations with their configurations. Each key represents a unique integration name. + Required fields: + - aws_account_id: The AWS account ID to integrate with (12-digit number) + - role_arn: The ARN of the IAM role Spacelift will assume + Optional fields: + - external_id: Custom external ID for additional security (recommended) + - duration_seconds: Session duration (default: 900s, max: 3600s) + - generate_credentials_in_worker: Whether to generate AWS credentials in worker (default: false) + - labels: List of Spacelift labels to apply to the integration + - space_id: Target Spacelift space ID (default: "root") + EOT
- Add validation blocks for critical fields:
validation { condition = alltrue([for k, v in var.aws_integrations : can(regex("^\\d{12}$", v.aws_account_id))]) error_message = "AWS account IDs must be 12 digits." } validation { condition = alltrue([for k, v in var.aws_integrations : can(regex("^arn:aws:iam::\\d{12}:role/[\\w+=,.@-]+$", v.role_arn))]) error_message = "Role ARN must be a valid IAM role ARN." } validation { condition = alltrue([for k, v in var.aws_integrations : v.duration_seconds == null || (v.duration_seconds >= 900 && v.duration_seconds <= 3600)]) error_message = "Duration seconds must be between 900 and 3600 seconds." }
- Security recommendation:
validation { condition = alltrue([for k, v in var.aws_integrations : v.external_id != null]) error_message = "External ID is strongly recommended for security. Set it explicitly or remove this validation if not required." }examples/complete/variables.tf (1)
1-13: Well-structured variable definition with room for improvementThe variable structure is well-defined with appropriate types and optional fields. However, there are a few suggestions to enhance security and usability:
- The
duration_secondsdefault of 900 (15 minutes) is reasonable but should be documented why this specific value was chosen.- Consider adding validation blocks for:
duration_secondsto enforce AWS STS session duration limits (900-43200 seconds)aws_account_idto ensure it matches the AWS account ID formatrole_arnto validate ARN formatHere's how you could enhance the variable definition:
variable "aws_integrations" { - description = "Map of AWS integrations with their configurations." + description = <<-EOT + Map of AWS integrations with their configurations. Each key represents a unique integration name. + The duration_seconds default of 900 (15 minutes) aligns with AWS minimum session duration. + EOT type = map(object({ aws_account_id = string role_arn = string external_id = optional(string, null) duration_seconds = optional(number, 900) generate_credentials_in_worker = optional(bool, false) labels = optional(list(string), []) space_id = optional(string, "root") })) default = {} + + validation { + condition = alltrue([for k, v in var.aws_integrations : can(regex("^\\d{12}$", v.aws_account_id))]) + error_message = "AWS account IDs must be 12 digits." + } + + validation { + condition = alltrue([for k, v in var.aws_integrations : can(regex("^arn:aws:iam::\\d{12}:role/[\\w+=,.@-]+$", v.role_arn))]) + error_message = "Role ARN must be a valid AWS IAM role ARN." + } + + validation { + condition = alltrue([for k, v in var.aws_integrations : v.duration_seconds == null || (v.duration_seconds >= 900 && v.duration_seconds <= 43200)]) + error_message = "Duration seconds must be between 900 and 43200 (15 minutes and 12 hours)." + } }examples/complete/context.tf (2)
23-46: Consider updating to the latest patch versionThe module version is pinned to
0.25.0, but version0.25.1is available with bug fixes. Consider updating to the latest patch version while maintaining backward compatibility.Otherwise, the module declaration looks good with proper variable passing and version constraints.
50-95: Consider using a more specific type definitionWhile
type = anyworks, consider using a more specific type definition using Terraform's object type for better type safety and documentation:type = object({ enabled = optional(bool) namespace = optional(string) tenant = optional(string) environment = optional(string) stage = optional(string) name = optional(string) delimiter = optional(string) attributes = optional(list(string)) tags = optional(map(string)) additional_tag_map = optional(map(string)) regex_replace_chars = optional(string) label_order = optional(list(string)) id_length_limit = optional(number) label_key_case = optional(string) label_value_case = optional(string) descriptor_formats = optional(map(string)) labels_as_tags = optional(list(string)) })The validation rules are well implemented, ensuring proper label case values.

6-6: Utilize Label Module Variables for Standardized NamingInstead of manually formatting the
nameusingformat("%s-%s", each.key, each.value.aws_account_id), consider leveraging the variables provided by thecloudposse/label/nullmodule. This approach promotes consistency and adheres to best practices for labeling resources.Apply this diff to use label module variables:
module "integration_label" { for_each = var.aws_integrations source = "cloudposse/label/null" version = "0.25.0" - name = format("%s-%s", each.key, each.value.aws_account_id) + namespace = var.namespace + environment = var.environment + name = each.key + attributes = [each.value.aws_account_id] context = module.this.context }Ensure that
var.namespaceandvar.environmentare defined in your variables file. This change enhances the flexibility and clarity of your resource names.
10-20: Validate Optional Parameters and Provide DefaultsIn the
spacelift_aws_integrationresource, optional parameters likeduration_seconds,labels,space_id, andgenerate_credentials_in_workermight not always be set ineach.value. To prevent potential runtime errors, consider providing default values or input validation.Apply this diff to set default values using the
tryfunction:resource "spacelift_aws_integration" "default" { for_each = var.aws_integrations name = module.integration_label[each.key].id role_arn = each.value.role_arn external_id = each.value.external_id - duration_seconds = each.value.duration_seconds - labels = each.value.labels - space_id = each.value.space_id - generate_credentials_in_worker = each.value.generate_credentials_in_worker + duration_seconds = try(each.value.duration_seconds, null) + labels = try(each.value.labels, null) + space_id = try(each.value.space_id, null) + generate_credentials_in_worker = try(each.value.generate_credentials_in_worker, null) }Alternatively, you can set defaults in your
variables.tfor ensure that all keys are provided invar.aws_integrations.

9-11: Validate duration_seconds value
The duration_seconds of 1200 (20 minutes) should be validated against AWS IAM role session duration limits (15 minutes to 12 hours).
✅ Verification successful
Duration value of 1200 seconds is within AWS IAM role session duration limits
The configured duration of 1200 seconds (20 minutes) is valid as it falls within AWS IAM role session duration limits (15 minutes to 12 hours). The codebase shows this field is properly defined with a default value of 900 seconds (15 minutes), and the example's value of 1200 seconds is a reasonable increase from the default that remains well within AWS's limits.

💡 Codebase verification
Add documentation about worker credential generation security implications
The codebase lacks explicit documentation about the security implications of setting generate_credentials_in_worker = true. Consider adding a comment in the variables.tf file and updating the README.md to explain:
- The purpose of worker credential generation
- Security considerations when enabling this option
- Best practices for using this feature safely

After reading this, I'm a little worried that these child modules for spaces + aws-integration are too simple... Let's roll with them and think on it, but in reading them... all we're doing is creating some additional layer abstraction over the original resources that doesn't provide much value e.g. it doesn't provide much useful business logic and they only wrap single resources. That concerns me, but I think we go with it for now. In the future, we may want to rethink how we ship these types of resources.
Yeah, that's why my initial idea was to to create a subfolder with these. modules in |
Yeah... |
. Where we draw the line is hard. We have drawn it too wide this time around, but we'll come up with some better thoughts on how we deal with this in the future.
