20-40: Consider adding caching for Terraform plugins in the 'test' jobTo improve the efficiency of your workflow, consider adding a step to cache Terraform plugins. This can significantly speed up subsequent runs by avoiding repeated downloads of the same plugins.
You can add the following step after the 'Setup Terraform' step:
- name: Cache Terraform plugins uses: actions/cache@v3 with: path: ~/.terraform.d/plugin-cache key: ${{ runner.os }}-terraform-${{ hashFiles('**/.terraform.lock.hcl') }} restore-keys: | ${{ runner.os }}-terraform- - name: Configure Terraform plugin cache run: | mkdir -p ~/.terraform.d/plugin-cache echo 'plugin_cache_dir = "~/.terraform.d/plugin-cache"' > ~/.terraformrcThis will cache the Terraform plugins based on the contents of your
.terraform.lock.hclfile.

52-53: Consider a more descriptive name for the 'terraform-plan' jobThe current name 'terraform-plan' doesn't fully capture that this job is specifically for pull requests and includes updating the PR with the plan output.
Consider renaming the job to something more descriptive, such as:
terraform-plan-pr: name: "Terraform Plan for PR"This makes it clearer at a glance what the job does and when it runs.

114-115: Refine the condition for the 'deploy' jobThe current condition
if: github.ref == 'refs/heads/main'ensures the job only runs on the main branch, but it doesn't specify the event type.Consider updating the condition to explicitly include the push event:
if: github.ref == 'refs/heads/main' && github.event_name == 'push'This ensures that the deploy job only runs on push events to the main branch, providing an additional layer of control over when deployments occur.

1-67: Clarification needed on "fix destroy plan" objectiveThe changes in this file address the "update eks node policy" part of the PR objectives by adding the
iam_role_additional_policiesattribute. However, I don't see any changes that seem to address the "fix destroy plan" part mentioned in the PR title.Could you please clarify:
- What issues were you experiencing with the destroy plan?
- Are there any other files or changes not shown here that address this issue?
- If not, what additional changes are needed to fix the destroy plan?
This information will help ensure that the PR fully meets its stated objectives.
To help identify any destroy-related issues, let's check for any TODO comments or destroy-related code:
#!/bin/bash # Search for destroy-related comments or code rg --type-add 'terraform:*.{tf,tfvars}' --type terraform -i '(todo|fixme|destroy)'This might give us some insights into any pending destroy-related tasks or issues in the Terraform code.
34-37: Consider refining the IAM policy for better security.While adding the
AmazonSQSFullAccesspolicy allows the EKS nodes to interact with SQS, granting full access to all nodes might be overly permissive. Consider the following suggestions:
- Instead of using the broad
AmazonSQSFullAccesspolicy, create a custom policy that grants only the specific SQS permissions required by your application.- If possible, limit the policy to specific SQS queues rather than all queues.
- Consider using IRSA (IAM Roles for Service Accounts) to grant SQS permissions only to the pods that need them, rather than to all nodes.
Here's an example of how you might refine this:
iam_role_additional_policies = { CustomSQSPolicy = aws_iam_policy.custom_sqs_policy.arn } # Define a custom SQS policy (in the appropriate location in your Terraform code) resource "aws_iam_policy" "custom_sqs_policy" { name = "CustomSQSPolicy" path = "/" description = "Custom SQS policy for EKS nodes" policy = jsonencode({ Version = "2012-10-17" Statement = [ { Effect = "Allow" Action = [ "sqs:SendMessage", "sqs:ReceiveMessage", "sqs:DeleteMessage", "sqs:GetQueueAttributes" ] Resource = "arn:aws:sqs:*:*:your-specific-queue-name" } ] }) }This approach provides more granular control over the permissions granted to your EKS nodes.
To ensure we're not overlooking any specific SQS requirements, let's check for SQS usage in the codebase:
This will help us tailor the IAM policy to the actual needs of your application.

184-184: Excellent addition of the environment key to the destroy-plan job!This change aligns the destroy-plan job with other jobs in the workflow by specifying the 'dev' environment. It ensures consistency and allows for environment-specific configurations and secrets to be used in this job. This improvement enhances the overall organization and management of the workflow, and directly addresses the PR objective to "fix destroy plan".
