+# Design Document
+
+## Overview
+
+The Docker socket permission error (EACCES) occurs because the homelabarr-backend container lacks proper permissions to access the Docker daemon socket at `/var/run/docker.sock`. The current implementation attempts to change socket permissions using `chmodSync()`, but this fails because the container runs as a non-root user (`node`) and cannot modify system-level socket permissions.
+
+The solution involves configuring proper Docker group membership and socket access through container orchestration rather than runtime permission changes.
+
+## Architecture
+
+The fix operates at multiple layers:
+
+1. **Container Build Layer** - Ensure proper user/group configuration in Dockerfile
+2. **Container Runtime Layer** - Configure group membership and socket mounting in docker-compose
+3. **Application Layer** - Implement robust error handling and retry logic
+4. **Monitoring Layer** - Add proper logging and health checks for Docker connectivity
+
+## Components and Interfaces
+
+### Docker Group Configuration
+- **Host Group Mapping**: Map the host's docker group ID to the container
+- **User Group Membership**: Add the container user to the docker group
+- **Socket Permissions**: Ensure socket is accessible to docker group members
+
+### Container Configuration
+- **Dockerfile Updates**: Configure proper group membership during build
+- **Docker Compose Updates**: Set correct group_add configuration
+- **Environment Variables**: Configure socket path and connection settings
+
+### Application Layer Improvements
+- **Connection Retry Logic**: Implement exponential backoff for failed connections
+- **Error Handling**: Graceful degradation when Docker is unavailable
+- **Health Monitoring**: Enhanced health checks for Docker connectivity
+
+### Security Considerations
+- **Least Privilege**: Grant minimal necessary permissions
+- **Group-based Access**: Use group membership instead of privileged mode
+- **Socket Protection**: Maintain socket security while enabling access
+
+## Data Models
+
+### Docker Connection Configuration
+```javascript
+interface DockerConfig {
+  socketPath: string;
+  timeout: number;
+  retryAttempts: number;
+  retryDelay: number;
+  healthCheckInterval: number;
+}
+```
+
+### Connection State Management
+```javascript
+interface DockerConnectionState {
+  isConnected: boolean;
+  lastError: Error | null;
+  lastSuccessfulConnection: Date | null;
+  retryCount: number;
+  nextRetryAt: Date | null;
+}
+```
+
+### Error Classification
+```javascript
+interface DockerError {
+  type: 'permission' | 'connection' | 'timeout' | 'unknown';
+  code: string;
+  message: string;
+  recoverable: boolean;
+  retryAfter?: number;
+}
+```
+
+## Error Handling
+
+### Permission Errors (EACCES)
+- **Root Cause**: Container user lacks docker group membership
+- **Detection**: Monitor for EACCES errors on socket connection
+- **Resolution**: Configure proper group membership in container
+- **Fallback**: Log error and continue with degraded functionality
+
+### Connection Failures
+- **Retry Strategy**: Exponential backoff with maximum retry limit
+- **Circuit Breaker**: Temporarily stop retrying after consecutive failures
+- **Recovery**: Automatic reconnection when Docker becomes available
+
+### Socket Unavailability
+- **Detection**: Monitor socket file existence and permissions
+- **Logging**: Detailed error messages for troubleshooting
+- **Graceful Degradation**: Continue serving non-Docker endpoints
+
+## Testing Strategy
+
+### Permission Testing
+- Verify container can access Docker socket after configuration changes
+- Test that docker group membership is properly configured
+- Validate socket permissions are correctly set
+
+### Connection Resilience Testing
+- Test behavior when Docker daemon is stopped/started
+- Verify retry logic works correctly with various failure scenarios
+- Test graceful degradation when Docker is unavailable
+
+### Security Testing
+- Ensure container doesn't run with unnecessary privileges
+- Verify socket access is limited to required operations
+- Test that security boundaries are maintained
+
+### Integration Testing
+- Test full container deployment with fixed configuration
+- Verify Docker operations work correctly after fix
+- Test health check endpoints report correct Docker status
+
+## Implementation Approach
+
+### Phase 1: Container Configuration Fix
+1. Update Dockerfile to properly configure docker group
+2. Modify docker-compose.yml to set correct group_add values
+3. Remove ineffective chmod attempts from application code
+
+### Phase 2: Application Layer Improvements
+1. Implement robust Docker connection management
+2. Add retry logic with exponential backoff
+3. Enhance error logging and monitoring
+
+### Phase 3: Health and Monitoring
+1. Improve health check to properly report Docker status
+2. Add connection state monitoring
+3. Implement graceful degradation for Docker unavailability
+
+### Phase 4: Security Hardening
+1. Verify minimal privilege configuration
+2. Add security validation for Docker operations
+3. Implement proper error boundaries
+
+## Security Considerations
+
+### Docker Socket Access
+- Use group-based permissions instead of privileged mode
+- Limit socket access to necessary operations only
+- Monitor and log all Docker API calls
+
+### Container Security
+- Run as non-root user with minimal required permissions
+- Use specific group membership rather than broad privileges
+- Implement proper input validation for Docker operations
+
+### Host System Protection
+- Ensure container cannot escape to host system
+- Limit Docker operations to safe, necessary functions
+- Implement proper audit logging for security monitoring

+# Requirements Document
+
+## Introduction
+
+This feature addresses the Docker socket permission error (EACCES) that prevents the homelabarr-backend from accessing Docker containers. The application is running in a Docker container and needs to communicate with the Docker daemon on the host system to manage other containers, but lacks the necessary permissions to access /var/run/docker.sock.
+
+## Requirements
+
+### Requirement 1
+
+**User Story:** As a homelabarr-backend service, I want to access the Docker socket, so that I can fetch and manage Docker containers without permission errors.
+
+#### Acceptance Criteria
+
+1. WHEN the backend attempts to connect to /var/run/docker.sock THEN the connection SHALL succeed without EACCES errors
+2. WHEN the Docker socket is mounted in the container THEN the backend process SHALL have read/write permissions
+3. WHEN fetching containers THEN the API calls SHALL complete successfully without permission denials
+
+### Requirement 2
+
+**User Story:** As a system administrator, I want secure Docker socket access, so that the container can manage Docker resources without compromising host security.
+
+#### Acceptance Criteria
+
+1. WHEN mounting the Docker socket THEN only necessary permissions SHALL be granted
+2. WHEN the container accesses Docker THEN it SHALL use the least privilege principle
+3. WHEN running in production THEN Docker socket access SHALL be properly secured
+
+### Requirement 3
+
+**User Story:** As a developer, I want consistent Docker socket access across environments, so that the application works reliably in development, testing, and production.
+
+#### Acceptance Criteria
+
+1. WHEN running via docker-compose THEN Docker socket access SHALL work consistently
+2. WHEN running on different host systems THEN the socket mounting SHALL adapt to the environment
+3. WHEN deploying to different platforms THEN Docker access SHALL remain functional
+
+### Requirement 4
+
+**User Story:** As a homelabarr user, I want the backend to gracefully handle Docker connection failures, so that the application remains stable even when Docker access is temporarily unavailable.
+
+#### Acceptance Criteria
+
+1. WHEN Docker socket access fails THEN the backend SHALL log appropriate error messages
+2. WHEN Docker is temporarily unavailable THEN the backend SHALL implement retry logic with exponential backoff
+3. WHEN Docker access is restored THEN the backend SHALL automatically reconnect without requiring restart

+```
+
+## Troubleshooting
+
+### Common Issues and Solutions
+
+#### 1. Permission Denied (EACCES)
+**Symptoms**: Socket access denied errors
+**Solutions**:
+- Verify Docker group membership: `groups $USER`
+- Check Docker socket permissions: `ls -la /var/run/docker.sock`
+- Ensure DOCKER_GID is set correctly in docker-compose.yml
+- Restart Docker service if needed
+
+#### 2. Docker Daemon Not Running
+**Symptoms**: Connection refused errors
+**Solutions**:
+- Start Docker Desktop (Windows/macOS)
+- Start Docker daemon: `sudo systemctl start docker` (Linux)
+- Verify Docker status: `docker info`
+
+#### 3. Server Not Running
+**Symptoms**: Health check tests fail with connection refused
+**Solutions**:
+- Start the server: `npm run dev`
+- Or start backend only: `node server/index.js`
+- Verify server is listening on port 3001
+
+#### 4. Missing Dependencies
+**Symptoms**: Module not found errors
+**Solutions**:
+- Install dependencies: `npm install`
+- Verify package.json exists
+- Check Node.js version compatibility
+
+#### 5. Container Group Membership Issues
+**Symptoms**: Tests pass locally but fail in container
+**Solutions**:
+- Verify group_add configuration in docker-compose.yml
+- Check DOCKER_GID environment variable
+- Ensure container user is added to docker group at runtime
+
+### Docker Group Configuration
+
+#### Finding Docker Group ID
+```bash
+# Linux
+getent group docker | cut -d: -f3
+
+# Alternative
+grep docker /etc/group | cut -d: -f3
+
+# macOS
+dscl . -read /Groups/docker PrimaryGroupID
+```
+
+#### Setting DOCKER_GID
+```bash
+# Set environment variable
+export DOCKER_GID=$(getent group docker | cut -d: -f3)
+
+# Use in docker-compose
+DOCKER_GID=$(getent group docker | cut -d: -f3) docker-compose up -d
+```
+
+## Integration with CI/CD
+
+### GitHub Actions Example
+```yaml
+- name: Test Docker Socket Access
+  run: |
+    export DOCKER_GID=$(getent group docker | cut -d: -f3)
+    node test-docker-socket-fix.js
+```
+
+### Docker Compose Testing
+```bash
+# Test with docker-compose
+DOCKER_GID=$(getent group docker | cut -d: -f3) docker-compose up -d
+node test-docker-socket-fix.js
+docker-compose down
+```
+
+## Test Configuration
+
+### Customizing Test Behavior
+
+The test script supports various configuration options:
+
+```javascript
+const TEST_CONFIG = {
+  socketPath: process.env.DOCKER_SOCKET || '/var/run/docker.sock',
+  timeout: 10000,
+  testContainerName: 'homelabarr-socket-test',
+  testImage: 'alpine:latest',
+  backendContainerName: 'homelabarr-backend',
+  frontendContainerName: 'homelabarr-frontend'
+};
+```
+
+### Environment-Specific Testing
+
+#### Development Environment
+```bash
+NODE_ENV=development node test-docker-socket-fix.js
+```
+
+#### Production Environment
+```bash
+NODE_ENV=production DOCKER_SOCKET=/var/run/docker.sock node test-docker-socket-fix.js
+```
+
+## Security Considerations
+
+The tests validate that:
+- Container runs with minimal required permissions
+- Docker socket access is group-based, not privileged mode
+- No unnecessary system privileges are granted
+- Socket permissions are properly restricted
+
+## Performance Testing
+
+The tests include timing information for:
+- Connection establishment

+## Docker Socket Configuration
+
+The backend container needs access to the Docker socket to manage containers. This is configured automatically, but you may need to adjust settings for your system.
+
+### Windows (Docker Desktop)
+```powershell
+# Run the detection script
+.\scripts\detect-docker-gid.ps1
+
+# This will configure the DOCKER_GID in your .env file
+```
+
+### Linux
+```bash
+# Run the detection script
+./scripts/detect-docker-gid.sh
+
+# Or manually find your docker group ID
+getent group docker | cut -d: -f3
+
+# Set the environment variable
+export DOCKER_GID=$(getent group docker | cut -d: -f3)
+docker-compose up -d
+```
+
+### Manual Configuration
+If the scripts don't work, you can manually set the Docker group ID in your `.env` file:
+
+```bash
+# Add to .env file
+DOCKER_GID=999  # Replace with your system's docker group ID
+DOCKER_SOCKET=/var/run/docker.sock
+```
