variables.tf (1)
4-4: Verify dependent configurations foreks_vpc_name.The default value of the
eks_vpc_namevariable has been updated to "eks-fiap-vpc". Ensure that all dependent configurations or modules that use this variable are updated accordingly to prevent any potential issues.Verification successful
Dependent configurations for
eks_vpc_nameare consistent.The
eks_vpc_namevariable is used inmain.tfto set a name property, and its usage appears consistent with the updated default value. No further dependent configurations were identified that require updates.

modules/eks/main.tf (3)
3-3: Good practice: Flexible version constraint.Changing the version constraint to
"~> 20.23.0"allows for minor version updates, which helps keep dependencies up-to-date without introducing breaking changes.
52-52: Correct data type for tag value.Changing the
Terraformtag value to a string"true"aligns with Terraform's requirement for tag values to be strings, preventing potential type-related issues.
53-53: Enhanced resource tracking withCreatedtag.Adding the
Createdtag withtimestamp()enhances resource management by providing dynamic tracking of creation time, which is beneficial for auditing purposes.output.tf (5)
35-38: Restored output forcluster_arn.Uncommenting the
cluster_arnoutput makes the ARN available for integrations, which is essential for further use in other modules or services.
40-43: Restored output forcluster_certificate_authority_data.Uncommenting this output is crucial for secure communication with the EKS cluster, as it provides necessary certificate data.
45-48: Restored output forcluster_endpoint.Uncommenting this output is necessary for accessing the Kubernetes API server, facilitating integrations and management.
50-53: Restored output foroidc_provider.Uncommenting this output is important for identity and access management, providing the OIDC provider URL necessary for authentication integrations.
55-58: Restored output foroidc_provider_arn.Uncommenting this output is crucial for identity and access management, especially when
enable_irsais true, providing the necessary ARN for configurations.modules/loadbalancer-controller/main.tf (3)
4-4: Good practice: Flexible version constraint for IAM role module.Setting the version constraint to
"~> 5.44.0"allows for minor version updates, ensuring compatibility and up-to-date dependencies.
18-18: Ensures correct resource creation order withdepends_on.Adding
depends_onensures that thekubernetes_service_accountis created only after the IAM role, preventing potential dependency issues.
73-92: New Kubernetes service resource for load balancing.The addition of
kubernetes_service.bmb-api-svcfacilitates the deployment of a LoadBalancer, with appropriate annotations and configuration for AWS integration and TCP traffic handling..github/workflows/terraform.yml (2)
85-87: Consider the impact of removing-auto-approve.The removal of the
-auto-approveflag means that manual approval is now required for Terraform apply actions, which could disrupt automated workflows. Ensure that this change aligns with your deployment strategy and security practices.Would you like assistance in automating the approval process while maintaining security?
85-87: Ensure environment variables are set correctly.The use of environment variables
BMB_EKS_CLUSTER_VPCandBMB_EKS_CLUSTER_NAMEis a good practice for dynamic configuration. Verify that these variables are correctly set in all environments where this workflow runs..terraform.lock.hcl (6)
6-6: Review AWS provider version constraints.The AWS provider constraints have been simplified to
">= 5.46.0, ~> 5.62.0". This ensures compatibility with the 5.62.x series but restricts updates to major versions. Ensure this aligns with your infrastructure requirements.Would you like assistance in verifying compatibility with your existing infrastructure?
67-82: Check Kubernetes provider version update.The Kubernetes provider version is updated from
2.31.0to2.32.0. Ensure that this update is compatible with your current Kubernetes cluster setup.Would you like assistance in verifying compatibility with your Kubernetes cluster?
125-140: Review TLS provider version update.The TLS provider is updated to version
4.0.5. Ensure this update is compatible with your security and encryption requirements.Would you like assistance in verifying compatibility with your security policies?
85-103: Consider the addition of the Null provider.The
nullprovider is added with version3.2.2. This provider is often used for lifecycle management and triggers. Ensure its usage is justified and correctly implemented in your configuration.
27-45: Evaluate the addition of the Cloudinit provider.The
cloudinitprovider is added with version2.3.4. Ensure that this addition is necessary for your infrastructure and that it integrates well with your existing setup.
105-123: Assess the addition of the Time provider.The
timeprovider is added with version0.12.0. This provider is useful for scheduling and time-based triggers. Ensure its addition is necessary and properly integrated.
