Credential Management Fixes - Documentation Sync with Business Logic

🚨 Issues Identified and Fixed

❌ Previous Issues (Fixed)

1. Hardcoded Account ID Mappings

   • Problem: The CLI script contained hardcoded mappings like:

     account_env_mapping = {
         "123456789012": "PROD",
         "123456789013": "STAGING", 
         "123456789014": "DEV"
     }

   • Impact: Only worked with specific account IDs, not flexible for real-world usage
   • Risk: Users would need to modify code for their own account IDs

2. Hardcoded Secret Name Mappings

   • Problem: AWS Secrets Manager integration had hardcoded secret names:

     account_secret_mapping = {
         "123456789012": "inventag/credentials/production",
         "123456789013": "inventag/credentials/staging"
     }

   • Impact: Only worked with predefined secret names
   • Risk: Required code changes for different secret naming conventions

3. Documentation-Code Mismatch

   • Problem: Documentation showed flexible examples but code was hardcoded
   • Impact: Users following documentation would encounter runtime failures
   • Risk: Poor user experience and loss of trust

✅ Solutions Implemented

1. Flexible GitHub Actions Credential Management

New Implementation:

def _apply_github_secrets_credentials(accounts):
    for account in accounts:
        # Try multiple environment variable naming patterns
        env_patterns = [
            f"AWS_ACCESS_KEY_ID_{account.account_id}",
            f"AWS_ACCESS_KEY_ID_{_sanitize_env_name(account.account_name).upper()}",
            f"{_sanitize_env_name(account.account_name).upper()}_AWS_ACCESS_KEY_ID",
            f"AWS_ACCESS_KEY_ID_{account.account_id[-4:]}",
        ]
        # Automatically tries all patterns until credentials are found

Benefits:

• ✅ Works with any account ID (e.g., 999888777666, 111222333444)
• ✅ Works with any account name (e.g., My Custom Production Environment)
• ✅ Multiple naming pattern support
• ✅ No code changes required for different accounts

2. Flexible AWS Secrets Manager Integration

New Implementation:

def _apply_aws_secrets_manager_credentials(accounts):
    for account in accounts:
        # Try multiple secret name patterns
        secret_patterns = [
            os.environ.get(f'INVENTAG_SECRET_{_sanitize_env_name(account.account_name).upper()}'),
            f"inventag/credentials/{account.account_id}",
            f"inventag/credentials/{_sanitize_env_name(account.account_name).lower()}",
            f"inventag/{account.account_id}/credentials",
            f"inventag-{account.account_id}",
        ]
        # Automatically tries all patterns until secret is found

Benefits:

• ✅ Works with any secret naming convention
• ✅ Environment variable overrides for custom secret names
• ✅ Multiple fallback patterns
• ✅ Clear logging of which secrets were tried and found

3. Comprehensive Validation and Error Handling

New Implementation:

def _validate_account_credentials(accounts):
    accounts_without_credentials = []
    for account in accounts:
        has_credentials = bool(
            account.access_key_id or 
            account.profile_name or 
            account.role_arn
        )
        if not has_credentials:
            accounts_without_credentials.append(account)
    
    if accounts_without_credentials:
        # Provide environment-specific guidance
        environment = _detect_environment()
        if environment == "github_actions":
            logger.error("For GitHub Actions, set up secrets like:")
            for account in accounts_without_credentials:
                logger.error(f"  - AWS_ACCESS_KEY_ID_{account.account_id}")

Benefits:

• ✅ Clear error messages when credentials are missing
• ✅ Environment-specific guidance
• ✅ Lists all missing accounts
• ✅ Provides concrete next steps

4. Automated Testing and Verification

New Implementation:

• Created examples/test_credential_management.py to verify all functionality
• Tests multiple account IDs and names
• Verifies pattern matching works correctly
• Ensures no hardcoded dependencies

Test Results:

✅ All tests passed! Credential management is flexible and works with any account configuration.

🔑 Key Benefits:
  • No hardcoded account IDs or mappings
  • Works with any account names and IDs
  • Multiple naming pattern support
  • Environment variable overrides
  • Clear error messages when credentials are missing
  • Automatic environment detection
