🚨 Advanced Error Resolution and Debugging Excellence

Critical CloudFormation Error Analysis and Resolution

This project involved sophisticated debugging and resolution of multiple complex CloudFormation deployment errors, demonstrating advanced troubleshooting skills and deep understanding of AWS resource interdependencies.

Error 1: IAM Role Not Found Exception

Error Message: "The role with name codebuild-nextwork-devops-cicd-service-role cannot be found."

Root Cause Analysis: CloudFormation attempted to attach IAM policies to a service role before the role itself was created, causing a timing dependency issue where resources were created in incorrect order.

Solution Implementation: Added strategic DependsOn attributes to four IAM managed policy resources, explicitly instructing CloudFormation to create the IAM role before attempting policy attachments.

Technical Resolution:

CodeArtifact Access Policy - Added DependsOn: "IAMRoleCodebuildnextworkdevopscicdservicerole"
CodeBuild Base Policy - Explicit dependency on IAM role creation
CodeDeploy Base Policy - Proper resource ordering implementation
EC2 Instance Base Policy - Sequential dependency management

Error 2: Circular Dependency Resolution

Error Message: Circular dependency detected between IAM policies and roles

Root Cause Analysis: IAM policies were configured to depend on roles (via DependsOn), while roles simultaneously referenced the same policies through ManagedPolicyArns, creating an unresolvable dependency loop.

Solution Implementation: Removed ManagedPolicyArns references from IAM role definitions that caused bidirectional dependencies, implementing unidirectional dependency flow from policies to roles.

Dependency Resolution Strategy:

🔧 Eliminated Bidirectional References - Removed ManagedPolicyArns from role definitions causing circular dependencies
📋 Maintained Policy Attachments - Used DependsOn attributes for proper resource ordering
🎯 Implemented Linear Dependencies - Created clear dependency chain without circular references

Error 3: CodeStar Connections Host Configuration

Error Message: "Resource specifies a HostArn that your account does not own"

Root Cause Analysis: CloudFormation template incorrectly specified HostArn for GitHub.com connections, which is only required for self-hosted Git providers like GitHub Enterprise Server.

Solution Implementation: Removed CodeStarConnections resource and HostArn configuration, switching to legacy GitHub OAuth authentication for CodeBuild source integration.

🎨 Manual Resource Addition and Template Enhancement

Advanced Resource Implementation

Two critical resources required manual addition to the CloudFormation template due to IaC Generator limitations, demonstrating advanced CloudFormation development skills and complex resource configuration management.

🎯 Service Role Assignment - CodeDeploy role reference: IAMRoleNextWorkCodeDeployRole
🚀 Application Integration - CodeDeploy application reference: CodeDeployApplicationNextworkdevopscicd
⚙️ Deployment Configuration - Blue-green deployment strategies and rollback policies
📊 Target Group Management - EC2 instance targeting and deployment group configuration
