1-16: LGTM! Consider adding a pull request trigger for the plan action.The workflow name and trigger configuration look good. The combination of automatic triggers on push to master and manual dispatch with action input provides good flexibility.
Consider adding a pull request trigger for the 'plan' action. This would allow for automatic Terraform plan execution on pull requests, helping to catch potential issues earlier in the development process. Here's a suggested addition:
on: push: branches: - master pull_request: branches: - master workflow_dispatch: # ... (keep existing workflow_dispatch configuration)This change would run the 'plan' action automatically on pull requests to the master branch, providing early feedback on Terraform changes.
22-28: Authentication setup looks secure. Consider adding environment variable for project ID.The checkout and authentication steps are well-configured. Using workload identity for authentication is a secure practice.
Consider adding an environment variable for the Google Cloud project ID. This would make the workflow more flexible and easier to reuse across different projects. Here's a suggested addition:
env: PROJECT_ID: ${{ secrets.GCP_PROJECT_ID }} steps: # ... (keep existing steps) - id: auth uses: google-github-actions/[email protected] with: workload_identity_provider: ${{ secrets.GOOGLE_CLOUD_WORKLOAD_IDENTITY_PROVIDER }} project_id: ${{ env.PROJECT_ID }}Don't forget to add the
GCP_PROJECT_IDsecret to your GitHub repository secrets.
1-41: Overall, good start on the Terraform workflow. Consider implementing suggested improvements.The workflow provides a solid foundation for automating Terraform operations. Here's a summary of the key points and suggestions:
- The trigger configuration is good, but consider adding a pull request trigger for the plan action.
- Authentication is well set up using workload identity.
- Consider adding environment variables for better flexibility, especially for the GCP project ID.
- Pin the version of the Terraform setup action for consistency.
- Add backend configuration to the Terraform init step for proper state management.
- Consider using native Terraform commands instead of custom tasks for better standardization.
- Implement error handling and output capturing for Terraform commands.
Implementing these suggestions will enhance the robustness, security, and maintainability of your Terraform workflow.
As you continue to develop this workflow, consider the following architectural advice:
- Implement a strategy for managing different environments (e.g., dev, staging, prod) within the same workflow.
- Consider adding a step to validate the Terraform configuration before planning or applying.
- Implement a mechanism to handle long-running Terraform operations, such as using GitHub Actions'
timeout-minutesoption or splitting operations into multiple workflows.- Consider integrating with a cost estimation tool to provide insights on infrastructure costs before applying changes.

18-20: Job configuration looks good.The job configuration is simple and appropriate. Using the latest Ubuntu runner ensures access to up-to-date dependencies.
35-41: 🛠️ Refactor suggestionImprove error handling and consider using native Terraform commands.
The conditional execution of plan and apply is correctly implemented. However, there are some areas for improvement:
- Consider using native Terraform commands instead of 'task'. This would make the workflow more standard and easier to understand for those unfamiliar with your specific setup:
- name: Terraform Plan if: github.event.inputs.action == 'plan' run: terraform plan -out=tfplan - name: Terraform Apply if: github.event.inputs.action == 'apply' run: terraform apply -auto-approve tfplan
- Add error handling and output capturing:
- name: Terraform Plan if: github.event.inputs.action == 'plan' run: | terraform plan -out=tfplan || exit 1 echo "Terraform Plan Output:" >> $GITHUB_STEP_SUMMARY terraform show -no-color tfplan >> $GITHUB_STEP_SUMMARY - name: Terraform Apply if: github.event.inputs.action == 'apply' run: | terraform apply -auto-approve tfplan || exit 1 echo "Terraform Apply Output:" >> $GITHUB_STEP_SUMMARY terraform show -no-color >> $GITHUB_STEP_SUMMARYThis will ensure that the workflow fails if Terraform encounters any errors, and it will add the Terraform output to the workflow summary for easy review.
To verify the existence and content of the task files, run:
#!/bin/bash # Check for task files if [ -f "Taskfile.yml" ] || [ -f "Taskfile.yaml" ]; then echo "Taskfile found. Contents:" cat Taskfile.y*ml else echo "No Taskfile found. Consider using native Terraform commands." fiThis will help understand the current task setup and decide whether to keep using tasks or switch to native Terraform commands.

Missing backend configuration in Terraform Init
- The Terraform initialization does not include backend configuration, which is essential for state management in CI/CD environments.
🔗 Analysis chain
Pin Terraform setup action version and consider adding backend configuration.
- Pin the version of the Terraform setup action to ensure consistency:
- name: Setup Terraform
uses: hashicorp/[email protected] # Or the latest specific version- Consider adding backend configuration to the Terraform init step. This is important for state management, especially in a CI/CD context:
- name: Terraform Init
run: |
terraform init \
-backend-config="bucket=${{ secrets.TF_STATE_BUCKET }}" \
-backend-config="prefix=terraform/state"Don't forget to add the TF_STATE_BUCKET secret to your GitHub repository secrets.
To ensure the Terraform configuration includes a backend, run:
This will help verify that a backend is defined in your Terraform configuration.
🏁 Scripts executed
The following scripts were executed for the analysis:

18-20: Consider pinning the Ubuntu version.While using the latest Ubuntu version is generally good, pinning to a specific version (e.g.,
ubuntu-22.04) can ensure consistency across runs and prevent unexpected issues from OS updates.jobs: terraform: - runs-on: ubuntu-latest + runs-on: ubuntu-22.04

1-16: LGTM: Well-structured workflow trigger configuration.The workflow name is clear, and the trigger conditions are appropriate for a Terraform workflow. The manual trigger with action choice provides good flexibility for different use cases.
23-28: LGTM: Proper checkout and authentication setup.The checkout action is using the latest major version, and the authentication step is correctly pinned to a specific version. Using a workload identity provider for authentication is a secure approach.
29-33:⚠️ Potential issueAdd backend configuration to Terraform initialization.
The Terraform setup looks good, but the initialization step is missing backend configuration. This is crucial for proper state management in CI/CD environments.
Please refer to the previous comment about adding backend configuration:
- name: Terraform Init run: | terraform init \ -backend-config="bucket=${{ secrets.TF_STATE_BUCKET }}" \ -backend-config="prefix=terraform/state"Don't forget to add the
TF_STATE_BUCKETsecret to your GitHub repository secrets.

🛠️ Refactor suggestion
Enhance error handling and output capturing for Terraform steps.
While the conditional execution of plan and apply steps is correct, consider adding error handling and output capturing to improve the workflow's robustness and observability.
Here's an improved version of these steps:
- name: Terraform Plan
if: github.event.inputs.action == 'plan'
run: |
task terraform-plan 2>&1 | tee plan_output.txt
if [ ${PIPESTATUS[0]} -ne 0 ]; then
echo "Terraform plan failed"
exit 1
fi
- name: Terraform Apply
if: github.event.inputs.action == 'apply'
run: |
task terraform-apply 2>&1 | tee apply_output.txt
if [ ${PIPESTATUS[0]} -ne 0 ]; then
echo "Terraform apply failed"
exit 1
fi
- name: Upload Terraform Output
if: always()
uses: actions/upload-artifact@v3
with:
name: terraform-output
path: |
plan_output.txt
apply_output.txtThis change adds error checking and uploads the output as artifacts, which can be useful for debugging and auditing.

Nice 👌
Are you able to test this by running this on your branch (removing hardcoded main on L6)? Just to be sure that this works?

This is a limitation workflow dispatch works on main branch only regardless of which branch we declared in workflow
