Refactor GitHub Actions workflows and improve infrastructure isolation#53
Conversation
- Updated the bootstrap workflow to use `gha-runner.yml` instead of `bootstrap.yml`. - Introduced a new action to retrieve the latest Amazon Linux 2023 AMI from AWS SSM Parameter Store. - Modified the deploy-bastion workflow to utilize the new AMI retrieval action and removed unnecessary parameters. - Cleaned up the justfile and other workflows to reflect the changes in AMI handling and streamline the deployment process.

Claude finished @jfrench9's task —— View job PR Review CompleteI've reviewed the workflow refactoring changes. Overall, this is a solid refactoring that improves maintainability and consolidates infrastructure management. Here's my detailed feedback: Strengths1. New AMI Retrieval Action (.github/actions/get-latest-ami/action.yml)
2. GHA Runner Workflow (.github/workflows/gha-runner.yml)
3. Bastion Deployment Simplification (.github/workflows/deploy-bastion.yml)
4. Tunnel Script Enhancements (bin/tools/tunnels.sh)
5. Bastion UserData Script (bin/userdata/bastion.sh)
Issues & ConcernsCritical Issues1. Missing GitHub Actions Composite Actions (.github/workflows/gha-runner.yml) Lines 179-192 reference composite actions that don't appear to be part of this PR: - name: Monitor Stack Deployment
uses: ./.github/actions/monitor-stack-deployment # ❌ Not in changed files
- name: Refresh Auto Scaling Group Instances
uses: ./.github/actions/refresh-asg # ❌ Not in changed filesIssue: This workflow will fail if these actions don't exist in the repository. Recommendation: Either include these actions in this PR or use existing AWS CLI commands inline. 2. GHA Runner Workflow Network Validation Logic (.github/workflows/gha-runner.yml:71-104) The network isolation validation has a logic issue: # Check for VPC peering
PEERING=$(aws ec2 describe-vpc-peering-connections \
--filters "Name=requester-vpc-info.vpc-id,Values=${{ steps.default-vpc.outputs.vpc_id }}" \
"Name=accepter-vpc-info.vpc-id,Values=$APP_VPC_ID" \
--query "VpcPeeringConnections[*].VpcPeeringConnectionId" \
--output text 2>/dev/null || echo "")Issue: This only checks one direction of VPC peering. It should check both:
Recommendation: # Check for VPC peering in both directions
PEERING=$(aws ec2 describe-vpc-peering-connections \
--filters "Name=requester-vpc-info.vpc-id,Values=${{ steps.default-vpc.outputs.vpc_id }},$APP_VPC_ID" \
"Name=accepter-vpc-info.vpc-id,Values=${{ steps.default-vpc.outputs.vpc_id }},$APP_VPC_ID" \
--query "VpcPeeringConnections[*].VpcPeeringConnectionId" \
--output text 2>/dev/null || echo "")3. Bastion UserData CloudWatch Agent JSON Syntax (bin/userdata/bastion.sh:804-811) The CloudWatch agent configuration update has a syntax error: cat >> /opt/aws/amazon-cloudwatch-agent/etc/amazon-cloudwatch-agent.json << 'EOF_LOGS'
,{
"file_path": "/var/log/robosystems/admin-operations.log",
...
}
EOF_LOGSIssue: This appends malformed JSON to an existing complete JSON file. The leading comma ( Recommendation: Regenerate the entire CloudWatch agent config or use jq '.logs.logs_collected.files.collect_list += [{
"file_path": "/var/log/robosystems/admin-operations.log",
"log_group_name": "/robosystems/${Environment}/bastion-host",
"log_stream_name": "${INSTANCE_ID}/admin-operations",
"timezone": "UTC"
}]' /opt/aws/amazon-cloudwatch-agent/etc/amazon-cloudwatch-agent.json > /tmp/cw-config.json
mv /tmp/cw-config.json /opt/aws/amazon-cloudwatch-agent/etc/amazon-cloudwatch-agent.jsonMedium Priority Issues4. Tunnel Script SSH Key Permission Check (bin/tools/tunnels.sh:261-267) local perms=$(stat -f "%OLp" "$key_path" 2>/dev/null || stat -c "%a" "$key_path" 2>/dev/null)Issue: The Recommendation: Detect OS first: if [[ "$OSTYPE" == "darwin"* ]]; then
local perms=$(stat -f "%OLp" "$key_path")
else
local perms=$(stat -c "%a" "$key_path")
fi5. GHA Runner Workflow Runner Availability Check (.github/workflows/gha-runner.yml:211-238) ONLINE_RUNNERS=$(echo "$RUNNERS_RESPONSE" | jq -r '.runners[] | select(.status == "online") | .name' | wc -l)
if [ "$ONLINE_RUNNERS" -ge 1 ]; then
echo "✅ $ONLINE_RUNNERS runner(s) online and ready"
break
fiIssue: This checks for ANY online runner, not specifically the newly deployed ones. If old runners are online, this will succeed even if new runners failed to register. Recommendation: Add a check for runners with recent registration timestamps or specific labels matching this deployment. 6. CloudFormation Template Version Constraint (cloudformation/gha-runner.yaml:219) The launch template has GHARunnerLaunchTemplate:
Type: AWS::EC2::LaunchTemplate
DeletionPolicy: Delete
UpdateReplacePolicy: Delete # ❌ This will delete the template on updatesIssue: With Recommendation: Change to UpdateReplacePolicy: Retain7. Missing Error Handling in Bastion Migration Script (bin/userdata/bastion.sh:295-306) RDS_ENDPOINT=$(aws cloudformation describe-stacks \
--stack-name RoboSystemsPostgresIAMProd \
--query "Stacks[0].Outputs[?OutputKey=='DatabaseEndpoint'].OutputValue" \
--output text)Issue: No validation that Recommendation: RDS_ENDPOINT=$(aws cloudformation describe-stacks \
--stack-name RoboSystemsPostgresIAMProd \
--query "Stacks[0].Outputs[?OutputKey=='DatabaseEndpoint'].OutputValue" \
--output text)
if [[ -z "$RDS_ENDPOINT" || "$RDS_ENDPOINT" == "None" ]]; then
print_error "Failed to retrieve RDS endpoint"
exit 1
fiMinor Issues / Suggestions8. Inconsistent Emoji Usage Per CLAUDE.md guidelines:
The bastion userdata script (bin/userdata/bastion.sh) is a background script but uses emojis in several places (lines 526, 689, etc.). The tunnel script correctly uses emojis since it's interactive. Recommendation: Remove emojis from bastion userdata script logging. 9. GHA Runner Instance Type Selection (cloudformation/gha-runner.yaml:335-340) The mixed instance policy lists 6 instance types: Overrides:
- InstanceType: t3a.medium
- InstanceType: t3.medium
- InstanceType: c6a.large # More expensive
- InstanceType: c6i.large # More expensive
- InstanceType: c7a.large # More expensive
- InstanceType: c7i.large # More expensiveSuggestion: The c6/c7 large instances are significantly more expensive than t3 mediums. Consider if the additional compute is needed for CI workloads or if it's better to limit to t3 instances only. 10. Tunnel Script User Input Validation (bin/tools/tunnels.sh:1090-1092) read -r direct_choice < /dev/ttyIssue: No timeout on user input. If run in automation, this could hang indefinitely. Recommendation: Add timeout: read -r -t 30 direct_choice < /dev/tty || direct_choice="2"Testing Recommendations
SummaryOverall Assessment: ✅ Approve with recommendations This is a solid refactoring that:

Claude finished @jfrench9's task —— View job PR Goals Verification CompleteI've thoroughly reviewed all changes to verify that the PR accomplishes its stated goals and that the critical issues from my previous review have been addressed. PR Goals Status✅ Workflow Optimization
✅ New Infrastructure Components
✅ Infrastructure Improvements
Critical Issues ResolutionAll three critical issues from my previous review have been FIXED: ✅ Issue #1: Missing Composite Actions (FIXED)Previous Issue: Lines 189-203 referenced Current Status: Both actions exist in the repository:
Verification: Used Glob tool to confirm all composite actions exist. ✅ Issue #2: VPC Peering Validation Logic (FIXED)Previous Issue: Network validation only checked one direction of VPC peering (default-vpc → app-vpc), missing the reverse direction. Current Status: Fixed in The workflow now properly checks both directions: # Check default-vpc → app-vpc
PEERING1=$(aws ec2 describe-vpc-peering-connections \
--filters "Name=requester-vpc-info.vpc-id,Values=${{ steps.default-vpc.outputs.vpc_id }}" \
"Name=accepter-vpc-info.vpc-id,Values=$APP_VPC_ID" \

if [ -n "$PEERING1" ] || [ -n "$PEERING2" ]; then
echo "❌ ERROR: VPC peering detected between default VPC and application VPC"
exit 1
fi✅ Issue #3: CloudWatch Agent JSON Syntax (FIXED)Previous Issue: Current Status: Fixed in Now uses jq --arg env "$Environment" --arg instance "$INSTANCE_ID" \
'.logs.logs_collected.files.collect_list += [{
"file_path": "/var/log/robosystems/admin-operations.log",
"log_group_name": ("/robosystems/" + $env + "/bastion-host"),
"log_stream_name": ($instance + "/admin-operations"),
"timezone": "UTC"

mv /tmp/cw-config.json /opt/aws/amazon-cloudwatch-agent/etc/amazon-cloudwatch-agent.jsonThis ensures valid JSON and proper CloudWatch agent configuration. Bonus ImprovementsSeveral medium-priority issues from my previous review have also been addressed: ✅ Runner Availability Check EnhancedPrevious Issue #5: Runner check looked for ANY online runner, not specifically newly deployed ones. Current Status: Fixed in The improved logic now:
This prevents false positives from pre-existing runners. ✅ Workflow Permissions AddressedCode Scanning Alert: GitHub Advanced Security flagged missing permissions. Current Status: Already set in permissions:
contents: readThe workflow properly limits GITHUB_TOKEN permissions to read-only, following security best practices. SummaryOverall Assessment: ✅ ALL GOALS ACCOMPLISHED This PR successfully achieves all stated objectives:
