+# Stacks Docker Images - AI Agent Guide
+
+## Security and Compliance Requirements
+
+⚠️ **CRITICAL**: Before making any changes to this repository, you MUST read and comply with the security guidelines in [copilot-security-instructions.md](./copilot-security-instructions.md). This includes requirements for GPG commit signing, branch protection policies, and security standards compliance.
+
+## Project Overview
+
+This repository builds a hierarchical set of Docker images for the Amido Stacks CI/CD pipeline. Images are layered from foundation to specialized tools, requiring careful build order and dependency management.
+
+## Architecture & Build System
+
+### Image Hierarchy
+
+Images follow a strict dependency chain:
+
+- **Foundation Layer**: `foundation/powershell` → `foundation/builder` → `foundation/azure-cli` → `foundation/tools`
+- **Specialized Images**: `java`, `dotnet`, `golang`, `node`, `infrastructure`, `inspec`, `data`, `kong`, `asciidoctor`
+- **Security Images**: `bottlerocket-cis-bootstrap`, `bottlerocket-cis-validation`
+
+Each image inherits from a parent via ARG-based registry/tag system:
+
+```dockerfile
+ARG REGISTRY=docker.io
+ARG IMAGE_TAG=0.0.1-workstation
+ARG ORG=ensono
+FROM ${REGISTRY}/${ORG}/eir-java:${IMAGE_TAG} AS base
+```
+
+### Build Workflow (Taskctl)
+
+All builds use `taskctl` with YAML configuration. Key patterns:
+
+- **Foundation images**: Built locally first (no container dependency)
+- **Specialized images**: Built using `powershell_docker` context (inside `eir-foundation-builder`)
+- **Multi-platform**: Supports `linux/amd64` and `linux/arm64` via `PLATFORM` env var
+
+**Critical build order**: Foundation images MUST build before dependent images.
+
+```bash
+# Build foundation (local machine)
+taskctl build:foundation:powershell
+taskctl build:foundation:builder
+
+# Build specialized (in container)
+taskctl build:dotnet
+taskctl build:java
+```
+
+## Key Configuration Files
+
+### `taskctl.yaml` - Build Orchestration
+
+- Defines pipelines for each image with proper dependencies
+- Uses templated variables: `IMAGE_NAME`, `DOCKER_BUILD_ARGS`, `DOCKER_IMAGE_TAG`
+- Context switching between local (`powershell`) and containerized (`powershell_docker`) builds
+
+### `build/taskctl/contexts.yaml` - Execution Environments
+
+- `powershell_docker`: Runs inside `ensono/eir-foundation-builder` container
+- `powershell`: Runs on host machine with pwsh
+- `docsenv`: Uses `ensono/eir-asciidoctor` for documentation builds
+
+### `build/scripts/Build-DockerImage.ps1` - Core Build Logic
+
+- Handles multi-arch builds with platform-specific tagging
+- Registry authentication and image pushing
+- Uses `Invoke-External` wrapper for command execution
+- Tag format: `{registry}/{name}:{version}-{arch}`
+
+## Development Patterns
+
+### Adding New Images
+
+1. Create `src/definitions/{name}/Dockerfile.ubuntu`
+2. Add `files/` directory with install scripts
+3. Update `taskctl.yaml` with new pipeline entry
+4. Add Azure DevOps stage in `build/azDevOps/docker-images.yml`
+5. Create documentation in `docs/docker-definitions/{name}.adoc`
+
+**Security Note**: All changes must follow the branch protection workflow outlined in [copilot-security-instructions.md](./copilot-security-instructions.md). Never commit directly to protected branches or bypass GPG signing requirements.
+
+### Version Management
+
+- Image versions controlled by `DOCKER_IMAGE_TAG` environment variable
+- Component versions set as Dockerfile ARGs (e.g., `SONARSCANNER_VERSION=11.0.0`)
+- Foundation image versions referenced in dependent images via build args
+
+### PowerShell Module Integration
+
+Uses `EnsonoBuild` PowerShell module for:
+
+- `Update-BuildNumber`: Sets `DOCKER_IMAGE_TAG`
+- `Invoke-External`: Command execution with dry-run support
+- `Invoke-Terraform`: Infrastructure management
+- `Confirm-Environment`: Environment validation
+
+## Infrastructure & Deployment
+
+### Azure Container Registry (ACR)
+
+- Terraform configuration in `deploy/terraform/azure/acr/`
+- Environment variables prefixed with `TF_VAR_`
+- Required variables: `name_company`, `name_component`, `name_project`
+
+### CI/CD Pipeline (Azure DevOps)
+
+- Multi-stage pipeline with dependency management
+- Each image has dedicated stage with `dependsOn` relationships
+- Supports multi-platform builds and manifest creation
+- Documentation generation integrated into build process
+
+## Documentation System
+
+- AsciiDoc-based using custom `ensono/eir-asciidoctor` image
+- Configuration in `docs.json` with PDF/HTML output
+- Auto-generates Docker Hub README files from AsciiDoc sources
+- Custom glob-include processor for dynamic content inclusion
+
+## Common Debugging Commands
+
+```bash
+# Check image dependencies
+taskctl build:foundation:powershell --dry-run
+
+# Debug build in container context
+docker run --rm -v ${PWD}:/app -w /app ensono/eir-foundation-builder:latest pwsh
+
+# Generate docs locally
+taskctl docs
+
+# Validate Terraform configuration
+taskctl infrastructure_variables
+taskctl infra:plan
+```
+
+## Environment Variables
+
+- `DOCKER_IMAGE_TAG`: Version for all images (set by `Update-BuildNumber`)
+- `DOCKER_CONTAINER_REGISTRY_NAME`: Target registry (default: docker.io)
+- `PLATFORM`: Build architecture (linux/amd64, linux/arm64)
+- `TF_VAR_*`: Terraform variables for ACR deployment

+title: "GitHub Copilot Security and Compliance Instructions"
+author: "Richard Slater"
+created: "2025-10-16"
+updated: "2025-10-16"
+version: "1.0"
+purpose: "Security and compliance guidelines for AI coding assistants"
+---
+
+# GitHub Copilot Security and Compliance Instructions
+
+## Core Security Principles
+
+GitHub Copilot MUST operate within established security controls and compliance frameworks. Under NO circumstances should Copilot suggest, implement, or assist in circumventing security measures.
+
+---
+
+## 1. GPG Commit Signing Requirements
+
+### Mandatory Behavior
+
+- **NEVER** disable, bypass, or suggest disabling GPG signing requirements
+- **NEVER** use flags like `--no-gpg-sign`, `-n`, or `git config commit.gpgsign false`
+- **ALWAYS** preserve existing GPG signing configurations
+- Check the git configuration, specifically that `git config commit.gpgsign` is set to true, and that `git config user.signingkey` is configured.
+
+### When GPG Signing Fails
+
+If a commit or operation fails due to GPG signing issues, Copilot MUST:
+
+1. **Halt the operation immediately** - Do not attempt to bypass or retry without signing
+2. **Alert the user with specific error details**:
+
+   ```markdown
+   ⚠️ GPG SIGNING FAILED
+
+   The commit operation failed due to GPG signing requirements.
+
+   Error: [specific error message]
+
+   Required Actions:
+
+   - Verify your GPG key is properly configured: `git config --list | grep gpg` in Bash/ZSH or `git config --list | select-string gpg` in PowerShell
+   - Check that your GPG key has not expired: `gpg --list-secret-keys --keyid-format LONG`
+   - Ensure your GPG agent is running: `gpgconf --list-components`
+   - Verify the signing key matches your commit email: `git config user.signingkey`
+
+   Please resolve the GPG configuration issue before continuing.
+   I cannot proceed with unsigned commits.
+   ```
+
+3. **Provide diagnostic commands** but NOT workarounds.
+4. **Wait for user confirmation** that the issue is resolved before retrying.
+
+### Acceptable GPG-Related Suggestions
+
+- Setting up GPG signing: `git config commit.gpgsign true`
+- Configuring a signing key: `git config user.signingkey <key-id>`
+- Verifying GPG configuration
+- Troubleshooting legitimate GPG issues
+
+---
+
+## 2. Branch Protection and Pull Request Requirements
+
+### 2.1 Mandatory Behavior
+
+- **NEVER** suggest force pushing to protected branches (`git push --force`, `git push -f`)
+- **NEVER** bypass branch protection rules using administrative privileges
+- **NEVER** commit directly to protected branches (main, master, production, release/\*)
+- **ALWAYS** follow the standard Software Development Lifecycle (SDLC)
+- **ALWAYS** use the tools at your disposal, such as the GitHub MCP Server, to identify branch protection rules and quality gates
+
+### Required Workflow for Protected Branches
+
+When changes need to be made to protected branches, Copilot MUST:
+
+1. **Create a feature branch** with descriptive naming:
+
+```bash
+git checkout -b feature/descriptive-name
+# or
+git checkout -b fix/issue-description
+```
+
+1. **Implement changes on the feature branch**.
+
+1. **Create a Pull Request** with:
+
+   - Clear title describing the change
+   - Detailed description including:
+     - Purpose of changes
+     - Security implications (if any)
+     - Testing performed
+     - Compliance considerations
+     - Backout Plan
+   - Linked issues or tickets
+   - Appropriate labels
+
+1. **Request required reviews** based on change type:
+
+   - Security changes: require security team review
+   - Infrastructure: require DevOps/SRE review
+   - Production configuration: require senior engineer + team lead review
+   - Change Advisory Board: require CAB review when Change Management Policy dictates it
+
+1. **Wait for CI/CD checks** to pass:
+
+   - Automated tests
+   - Security scans
+   - Code quality checks
+   - Compliance validation
+   - Path to live environment deployments
+
+1. **NEVER suggest merging your own PR** without appropriate approvals.
+
+### Branch Protection Alert
+
+If a user attempts to bypass branch protection, respond with:
+
+```markdown
+🛡️ BRANCH PROTECTION POLICY VIOLATION
+
+The requested operation would bypass branch protection rules on [branch-name].
+
+This violates established security controls and SDLC processes.
+
+Required Process:
+
+1. Create a feature branch from [base-branch]
+2. Implement and commit your changes
+3. Open a Pull Request with detailed description
+4. Obtain required approvals ([n] reviewers)
+5. Ensure all CI/CD checks pass
+6. Merge via approved PR process
+
+I cannot assist with bypassing branch protection policies, however, I can assist with producing the artifacts required to support following the branch protection policy.
+```
+
+---
+
+## 3. Production Configuration Change Control
+
+### 3.1 Mandatory Behavior
+
+- **NEVER** make direct changes to production configurations
+- **NEVER** skip change control processes, even for "minor" or "urgent" changes
+- **ALWAYS** follow the formal Change Management process where applicable
+- **ALWAYS** assist in producing the documentation required to adhere to the process
+
+### Production Configuration Scope
+
+Production configurations include but are not limited to:
+
+- Environment variables in production
+- Infrastructure as Code (IaC) for production environments
+- Database connection strings and credentials
+- API endpoints and service URLs
+- Feature flags affecting production
+- Load balancer and routing rules
+- Security group and firewall rules
+- Monitoring and alerting thresholds
+- Backup and disaster recovery configurations
+- SSL/TLS certificates and cryptographic settings
+
+### Required Change Control Process
+
+For ANY production configuration change, Copilot MUST guide users through:
+
+1. **Change Request Documentation**:
+
+   - Refer to [Company or Client Name] Change Management Function
+   - Provide content and resources to support a change request
+   - Document a backout plan clearly
+   - Consider implementing the change as a Standard (pre-approved and automated) change
+
+1. **Non-Production Validation**:
+
+   - Test in a development environment first
+   - Deploy to staging/pre-production
+   - Run automated and manual tests
+   - Perform security validation
+   - Document results
+
+1. **Approval Workflow**:
+
+   - Submit the change request
+   - Obtain required approvals
+   - Schedule the change window
+   - Coordinate with stakeholders
+
+1. **Implementation with Controls**:
+
+   - Execute during the approved change window
+   - Mark the change as in progress in the change management system
+   - Follow the run book exactly
+   - Maintain a communication channel
+   - Monitor key metrics
+   - Verify success criteria
+
+1. **Post-Implementation**:
+
+   - Document actual changes made
+   - Verify rollback procedures
+   - Update configuration documentation
+   - Close the change ticket
+   - Write up an improvement plan to automate the change in the future
+
+### Production Change Alert
+
+If a user attempts to make direct production configuration changes:
+
+```text
+🚨 PRODUCTION CHANGE CONTROL VIOLATION
+
+The requested operation would modify production configuration without following the required change control process.
+
+Configuration Type: [specific config]
+Risk Level: [High/Medium/Low]
+
+This violates:
+- Change Management Policy
+- ISO 27001:2013 Clause 12.1.2 (Change Management)
+- [Other relevant standards]
+
+Required Actions:
+1. Document the change request using the standard template
+2. Assess risk and security implications
+3. Test changes in non-production environment
+4. Submit for required approvals
+5. Schedule implementation during approved change window
+
+I cannot assist with uncontrolled production changes.
+```
+
+---
+
+## 4. Authentication and Authorization Controls
+
+### 4.1 Mandatory Behavior
+
+- **NEVER** disable authentication mechanisms
+- **NEVER** remove authorization checks
+- **NEVER** hard-code credentials or bypass credential management
+- **NEVER** suggest reducing security levels to "fix" access issues
+- **ALWAYS** maintain principle of least privilege
+
+### Prohibited Actions
+
+Copilot MUST NOT suggest or implement:
+
+❌ **Disabling Authentication**:
+
+```javascript
+// NEVER suggest this
+app.use((req, res, next) => {
+  // req.user = { id: 1, role: 'admin' }; // Bypassing auth
+  next();
+});
+
+// Or this
+if (process.env.NODE_ENV === "development") {
+  // Skip authentication
+}
+```
+
+❌ **Removing Authorization Checks**:
+
+```python
+# NEVER suggest this
+def sensitive_operation():
+    # if not user.has_permission('admin'):  # Commented out
+    #     raise PermissionError
+    perform_admin_action()
+```
+
+❌ **Hard-coded Credentials**:
+
+```yaml
+# NEVER suggest this
+database:
+  username: admin
+  password: Password123!
+  host: prod-db.example.com
+```
+
+❌ **Overly Permissive Access**:
+
+```json
+// NEVER suggest this
+{
+  "permissions": "*",
+  "resources": "*",
+  "actions": "*"
+}
+```
+
+❌ **Disabled Security Features**:
+
+```php
+// NEVER suggest this
+session.cookie_secure = false;
+session.cookie_httponly = false;
+header('Access-Control-Allow-Origin: *');
+```
+
+### Required Approaches
+
+✅ **Proper Authentication**:
+
+```javascript
+// Use established authentication middleware
+app.use(authenticate);
+app.use(requireRole(["admin", "editor"]));
+
+// Validate tokens properly
+const token = await verifyJWT(req.headers.authorization);
+```
+
+✅ **Authorization Checks**:
+
+```python
+@require_permission('resource:action')
+def sensitive_operation(user):
+    if not user.is_authorized(resource, action):
+        raise PermissionError("Insufficient privileges")
+    perform_action()
+```
+
+✅ **Secure Credential Management**:
+
+```yaml
+database:
+  username: ${DB_USERNAME} # From secure environment variables
+  password: ${DB_PASSWORD} # From secrets manager
+  host: ${DB_HOST}
+```
+
+✅ **Least Privilege**:
+
+```json
+{
+  "permissions": ["read:documents", "write:own_documents"],
+  "resources": ["/api/documents/*"],
+  "conditions": { "owner": "${user.id}" }
+}
+```
+
+### Security Control Alert
+
+If a user requests disabling authentication or authorization:
+
+```markdown
+🔐 AUTHENTICATION/AUTHORIZATION CONTROL VIOLATION
+
+The requested operation would disable or bypass security controls.
+
+Specific Issue: [description]
+
+This violates:
+
+- Authentication and Access Control Policy
+- ISO 27001:2013 Clause 9.2 (User Access Management)
+- NIST SP 800-53 AC-2 (Account Management)
+- NIST SP 800-53 AC-3 (Access Enforcement)
+- CIS Controls 6.x (Access Control Management)
+
+Security Implications:
+
+- Unauthorized access to sensitive resources
+- Violation of principle of least privilege
+- Compliance violations
+- Audit trail compromise
+
+Recommended Actions:
+
+1. Diagnose the underlying access issue
+2. Request appropriate permissions through IAM process
+3. Use service accounts with minimal required permissions
+4. Implement proper authentication flow
+5. Add authorization checks with audit logging
+
+I cannot assist with disabling security controls.
+```
+
+---
+
+## 5. Security Standards Compliance
+
+### Applicable Standards
+
+GitHub Copilot MUST validate all code suggestions against:
+
+- **ISO 27001:2013** - Information Security Management
+- **NIST SP 800-53** - Security and Privacy Controls

+
+# Line 34: FIPS VIOLATION - Weak random number generation
+import random
+token = random.randint(1000, 9999)  # Not cryptographically secure
+```
+
+✅ **Compliant**:
+
+```python
+# FIPS-compliant cryptographic operations
+import hashlib
+import secrets
+from cryptography.hazmat.primitives.ciphers import Cipher, algorithms, modes
+from cryptography.hazmat.backends import default_backend
+
+# Use SHA-256 or stronger

+
+---
+
+## 6. Audit and Logging Requirements
+
+### 6.1 Mandatory Behavior
+
+- **ALWAYS** include audit logging for security-relevant actions
+- **NEVER** suggest disabling or circumventing audit logs
+- **ALWAYS** log to immutable storage where available
+
+### Required Audit Events
+
+```javascript
+// All security-relevant events must be logged
+const AUDIT_EVENTS = {
+  AUTHENTICATION: ["login", "logout", "failed_login", "password_change"],
+  AUTHORIZATION: ["access_granted", "access_denied", "privilege_escalation"],
+  DATA_ACCESS: [
+    "read_sensitive",
+    "update_sensitive",
+    "delete_data",
+    "export_data",
+  ],
+  CONFIGURATION: ["config_change", "feature_flag_toggle", "deployment"],
+  SECURITY: ["encryption_key_rotation", "certificate_renewal", "security_scan"],
+};
+
+// Minimum log fields (ISO 27001 A.12.4.1)
+function auditLog(event) {
+  return {
+    timestamp: new Date().toISOString(),
+    eventType: event.type,
+    actor: event.userId,
+    actorIp: event.ipAddress,
+    action: event.action,
+    resource: event.resource,
+    result: event.success ? "SUCCESS" : "FAILURE",
+    severity: event.severity,
+    details: event.details,
+    sessionId: event.sessionId,
+  };
+}
+```
+
+---
+
+## 7. Incident Response
+
+If Copilot detects that a user is attempting to:
+
+- Respond to a security incident by bypassing controls
+- Make emergency changes without proper approval
+- Implement temporary "workarounds" that reduce security
+
+Response Template:
+
+```markdown
+🚨 SECURITY INCIDENT DETECTED
+
+I understand this may be an urgent situation, but security controls
+must be maintained even during incident response.
+
+Current Situation: [Summary]
+
+Required Incident Response Process:
+
+1. Declare incident to Security Team
+2. Activate Incident Response Plan
+3. Obtain emergency change approval from:
+   - Security Incident Commander
+   - [Other required approvers]
+4. Document all actions in incident log
+5. Implement changes with audit trail
+6. Schedule post-incident review
+
+I can help you:
+✅ Document the incident properly
+✅ Draft emergency change request
+✅ Implement secure temporary solutions
+✅ Create rollback procedures
+
+I cannot help you:
+❌ Bypass security controls
+❌ Skip approval processes
+❌ Implement insecure workarounds
+
+Please confirm you have incident response approval before proceeding.
+```

+[List of requested violations]
+
+These actions require:
+
+1. Written approval from Chief Information Security Officer (CISO)
+2. Risk acceptance documentation
+3. Compensating controls implementation plan
+4. Audit committee notification (for compliance-regulated changes)
+
+This conversation may be subject to security audit.
+
+Please contact your security team at [security@example.com] or open a security exception request at [URL].
+
+I am unable to proceed without proper authorization.
+```

+# Add AI Agent Guidance and Update SonarScanner Version
+
+## 📲 What
+
+This PR introduces comprehensive AI agent guidance documentation and updates the SonarScanner version in the .NET Docker image:
+
+1. **Added AI Agent Instructions** (`copilot-instructions.md`):
+
+   - Comprehensive guide for AI coding agents working with this Docker images repository
+   - Covers project architecture, build workflows, configuration patterns, and development procedures
+   - Documents the hierarchical image dependency system and critical build order requirements
+
+2. **Added Security Compliance Guidelines** (`copilot-security-instructions.md`):
+
+   - Detailed security and compliance requirements for AI agents
+   - Enforces GPG commit signing, branch protection policies, and SDLC processes
+   - Implements security standards compliance (ISO 27001, NIST, FIPS, PCI DSS, etc.)
+   - Provides specific examples of prohibited and compliant code patterns
+
+3. **Updated .NET Docker Image Dependencies**:
+   - SonarScanner version: `5.14` → `11.0.0` (major version upgrade)
+   - ReportGenerator version: `5.1.26` → `5.4.17` (maintenance update)
+
+## 🤔 Why
+
+**AI Agent Documentation**:
+
+- Enables AI coding assistants to be immediately productive in this codebase without extensive context gathering
+- Prevents common mistakes by documenting critical build order dependencies and project-specific patterns
+- Establishes clear security guardrails to maintain compliance and prevent policy violations
+
+**SonarScanner Update**:
+
+- Brings the .NET image up to the latest SonarScanner version for improved code quality analysis
+- Addresses potential security vulnerabilities and bugs in older versions
+- Ensures compatibility with modern .NET projects and SonarQube instances
+
+**Security Compliance**:
+
+- Enforces mandatory security controls that must never be bypassed
+- Implements audit trails and change management processes
+- Ensures all AI-generated code meets enterprise security standards
+
+## 🛠 How
+
+**Documentation Implementation**:
+
+- Created `.github/copilot-instructions.md` with project-specific guidance covering:
+
+  - Image hierarchy and dependency chain (`foundation/powershell` → `foundation/builder` → specialized images)
+  - Taskctl-based build system with context switching (local vs containerized builds)
+  - PowerShell module integration and environment variable management
+  - Critical debugging commands and development workflows
+
+- Created `.github/copilot-security-instructions.md` with enterprise security requirements:
+
+  - GPG commit signing enforcement with specific error handling procedures
+  - Branch protection workflow requiring feature branches and PR approvals
+  - Production change control processes with audit documentation
+  - Security standards compliance scanning (FIPS, PCI DSS, ISO 27001, OWASP)
+
+- Cross-referenced security guidelines in main instructions with prominent warnings
+
+**Version Updates**:
+
+- Modified `src/definitions/dotnet/Dockerfile.ubuntu`:
+  - Updated `SONARSCANNER_VERSION` ARG from `5.14` to `11.0.0`
+  - Updated `REPORTGENERATOR_VERSION` ARG from `5.1.26` to `5.4.17`
+- Maintained backward compatibility through ARG-based versioning system
+
+## 👀 Evidence
+
+- **Documentation**: Both guidance files follow established patterns and reference existing project structure
+- **Security**: All security examples are based on industry standards (ISO 27001, NIST SP 800-53, OWASP Top 10)
+- **Dockerfile Changes**: Version bumps are straightforward ARG updates with no breaking changes
+- **Integration**: Security instructions are properly referenced from main instructions file
+
+## 🕵️ How to test
+
+**AI Agent Documentation**:
+
+1. Validate that AI agents can understand project structure from the instructions
+2. Verify that all referenced files and commands exist and are accurate
+3. Test that build order dependencies are clearly documented and correct
+
+**Security Compliance**:
+
+1. Confirm that security guidelines cover all critical scenarios
+2. Verify GPG signing requirements are properly enforced
+3. Test branch protection workflow documentation matches actual repository settings
+
+**Docker Image Updates**:
+
+1. Build the updated .NET image locally: `taskctl build:dotnet`
+2. Verify SonarScanner 11.0.0 is properly installed in the container
+3. Test ReportGenerator 5.4.17 functionality with sample .NET projects
+4. Confirm no breaking changes in the tool interface or output formats
+
+**Integration Testing**:
+
+1. Validate that the entire build pipeline still works with updated versions
+2. Test multi-platform builds (`linux/amd64`, `linux/arm64`)
+3. Verify Azure DevOps pipeline compatibility with updated tools
+4. Confirm documentation generation processes remain functional
+
+**Security Validation**:
+
+1. Ensure branch protection rules are active and documented procedures match reality
+2. Verify GPG signing is enforced for all commits on protected branches
+3. Test that AI agents following the security guidelines cannot bypass established controls
