Staging EKS Infra 1.29 upgrade #3031
Conversation
WalkthroughThe pull request introduces a comprehensive Terraform configuration for an AWS-based infrastructure, specifically designed for a Kubernetes cluster. Key changes include the addition of modules for networking, database provisioning, IAM management, and EKS setup. New output declarations enhance visibility of critical infrastructure components, while the use of variables improves configurability. Minor formatting changes and updates to resource attributes ensure clarity and maintainability across the configuration files. Changes

17-32: Consider using Terraform variables or a secrets management solution to pass sensitive information.The usage of the
dbmodule to create a PostgreSQL database looks good and the required variables are being passed correctly.However, the database username and password are being passed directly, which is not a secure practice. Consider using Terraform variables or a secrets management solution like AWS Secrets Manager to pass sensitive information.
48-53: Consider removing the commented outload_config_fileargument if it's not needed.The Kubernetes provider configuration looks good and is using the cluster endpoint, certificate, and token from the respective data sources.
However, the
load_config_fileargument is commented out. If the provider doesn't need to load the kubeconfig file, consider removing the commented out line to keep the configuration clean.

12-12: LGTM!The new
db_subnet_groupvariable is a great addition for configuring the subnet group of the database. It enhances the flexibility and security of the database deployment.infra-as-code/terraform/egov-staging/remote-state/main.tf (3)
6-6: LGTM!Using a variable for the S3 bucket name is a great improvement. It makes the configuration more flexible and reusable.
13-18: LGTM!The new
aws_s3_bucket_versioningresource is a great addition for enabling versioning on the S3 bucket. This is crucial for maintaining the history of objects stored in the bucket.
22-22: LGTM!Using the same variable for the DynamoDB table name is a good change. It aligns the table name with the S3 bucket name and makes the configuration more consistent.
infra-as-code/terraform/modules/db/aws/outputs.tf (4)
5-7: LGTM!The new
db_instance_endpointoutput is a useful addition for exposing the database endpoint. This will make it easier to access the database from other resources.
9-12: LGTM!The new
db_instance_nameoutput is a useful addition for exposing the database name. This will make it easier to reference the database from other resources.
14-18: LGTM!The new
db_instance_usernameoutput is a useful addition for exposing the database master username. Marking the output as sensitive is crucial for security, as the username should not be exposed publicly.
20-23: LGTM!The new
db_instance_portoutput is a useful addition for exposing the database port. This will make it easier to connect to the database.infra-as-code/terraform/modules/db/aws/main.tf (2)
6-9: LGTM!The change from
maptotomapenhances clarity and aligns with best practices for defining key-value pairs in Terraform configurations.
24-24: Verify the impact of the change indb_subnet_group_name.The changes look good overall:
- The change from
maptotomapenhances clarity and aligns with best practices for defining key-value pairs in Terraform configurations.- The new attributes
auto_minor_version_upgrade,allow_major_version_upgrade,skip_final_snapshot, andapply_immediatelyprovide additional control over the behavior of the database instance, particularly regarding version upgrades and snapshot management.However, the change in
db_subnet_group_namefrom${aws_db_subnet_group.db_subnet_group.name}to${var.db_subnet_group}indicates a shift in how the subnet group is identified.Ensure that this change is thoroughly tested to confirm that it behaves as expected. Run the following script to verify the subnet group usage:
Also applies to: 26-29, 32-35
infra-as-code/terraform/egov-staging/outputs.tf (1)
1-58: LGTM!The new
outputs.tffile looks good. The declared outputs provide visibility into critical infrastructure components provisioned by the Terraform configuration, such as:
- VPC and subnet IDs
- EKS cluster endpoint and kubectl config
- Volume IDs for Elasticsearch, Zookeeper, and Kafka
- RDS instance details
This enhances the usability and maintainability of the Terraform configuration.
infra-as-code/terraform/egov-staging/variables.tf (1)
1-90: LGTM!The new
variables.tffile looks good. The declared input variables improve the configurability of the Terraform configuration by allowing customization of key parameters, such as:
- Cluster name and Kubernetes version
- VPC CIDR block and availability zones
- Worker node instance types and count
- Database name, username, and password
- SSH key details
This enhances the flexibility and reusability of the Terraform configuration across different environments.
