PR Review 🔍

⏱️ Estimated effort to review [1-5]	3, because the PR involves multiple files with Terraform configurations that require understanding of specific cloud services (DuploCloud) and infrastructure setup. The PR includes both module definitions and example usage, which increases the complexity slightly.
🧪 Relevant tests	No
⚡ Possible issues	Possible Security Issue: The user data script in modules/retool-bastion/main.tf uses hardcoded commands to modify ssh configurations and user settings. This could lead to security vulnerabilities if not properly secured or if the public key is exposed.
	Hardcoded Values: The public key is directly embedded in the Terraform configuration, which might not be suitable for production environments where keys should be managed securely.
🔒 Security concerns	- Sensitive Information Exposure: The public key for SSH access is hardcoded in the Terraform script, which could lead to exposure if the codebase is publicly accessible or not properly secured.

PR Code Suggestions ✨

Category	Suggestion	Score
Possible issue	Add error handling for cases where no AMI matches the regex pattern Add error handling for the case where no AMI matches the regex pattern in the locals block to avoid runtime errors. modules/retool-bastion/main.tf [2-5] ami = [ for image in data.duplocloud_native_host_images.current.images : image if length(regexall("Docker-Duplo-.*-AmazonLinux2$", image.name)) > 0 -][0].image_id +] +ami_id = length(ami) > 0 ? ami[0].image_id : "" Suggestion importance[1-10]: 8 Why: This suggestion correctly identifies a potential runtime error if no AMI matches the regex. Adding error handling improves robustness and prevents crashes.	8
Best practice	Add a region argument to the provider "duplocloud" block for proper AWS region configuration Consider adding a region argument to the provider "duplocloud" block to ensure the provider is configured to use the correct AWS region. examples/retool-bastion/main.tf [11-13] provider "duplocloud" { - + region = "us-west-2" } Suggestion importance[1-10]: 7 Why: Adding a region to the provider configuration is a best practice for clarity and to avoid potential issues with default regions. This suggestion is relevant and improves the configuration.	7
	Add a depends_on argument to ensure proper resource dependency handling Add a depends_on argument to the duplocloud_aws_host resource to ensure it waits for the duplocloud_native_host_images data source to be fully populated. modules/retool-bastion/main.tf [39-49] resource "duplocloud_aws_host" "bastion" { tenant_id = var.tenant_id friendly_name = var.name image_id = local.ami capacity = var.capacity keypair_type = 1 allocated_public_ip = true agent_platform = 0 zone = 0 base64_user_data = base64encode(local.user_data) + depends_on = [data.duplocloud_native_host_images.current] } Suggestion importance[1-10]: 7 Why: The suggestion to add a depends_on argument is valid as it ensures that the host resource creation waits for the data source to be ready, preventing potential timing issues.	7
Enhancement	Add a lifecycle block with create_before_destroy to ensure zero downtime during updates Add a lifecycle block with create_before_destroy set to true for the duplocloud_aws_host resource to ensure zero downtime during updates. modules/retool-bastion/main.tf [39-49] resource "duplocloud_aws_host" "bastion" { tenant_id = var.tenant_id friendly_name = var.name image_id = local.ami capacity = var.capacity keypair_type = 1 allocated_public_ip = true agent_platform = 0 zone = 0 base64_user_data = base64encode(local.user_data) + lifecycle { + create_before_destroy = true + } } Suggestion importance[1-10]: 6 Why: Adding a lifecycle block with create_before_destroy is a good enhancement for maintaining availability during updates, although it's not critical for functionality.	6

CI Failure Feedback 🧐

(Checks updated until commit e890c77)

Action: Test / Testing retool-bastion

Failed stage: TF Validate Example for Module [❌]

Failure summary: The action failed because Terraform exited with code 3. This indicates an error in the Terraform configuration or execution. The specific module involved is retool_bastion. The error occurred after setting up the backend configuration for AWS S3 and DynamoDB. The process completed with exit code 1, indicating a failure in the overall execution.

✨ CI feedback usage guide:

---

The CI feedback tool (/checks) automatically triggers when a PR has a failed check.
The tool analyzes the failed checks and provides several feedbacks:

• Failed stage
• Failed test name
• Failure summary
• Relevant error logs

In addition to being automatically triggered, the tool can also be invoked manually by commenting on a PR:

/checks "https://github.com/{repo_name}/actions/runs/{run_number}/job/{job_number}"

where {repo_name} is the name of the repository, {run_number} is the run number of the failed check, and {job_number} is the job number of the failed check.

Configuration options

• enable_auto_checks_feedback - if set to true, the tool will automatically provide feedback when a check is failed. Default is true.
• excluded_checks_list - a list of checks to exclude from the feedback, for example: ["check1", "check2"]. Default is an empty list.
• enable_help_text - if set to true, the tool will provide a help message with the feedback. Default is true.
• persistent_comment - if set to true, the tool will overwrite a previous checks comment with the new feedback. Default is true.
• final_update_message - if persistent_comment is true and updating a previous checks message, the tool will also create a new message: "Persistent checks updated to latest commit". Default is true.

See more information about the checks tool in the docs.
