gitlab-stack-creator（GitLab stack creator 搜索）

GitLab Stack Creator

Expert assistance for creating new GitLab stack projects with proper structure, git configuration, validation scripts, and comprehensive documentation.

When to Use This Skill

This skill should be triggered when:

• Creating a new GitLab stack project
• Initializing a Docker stack with proper structure
• Setting up a project with./config,./secrets,./_temporary directories
• Configuring git repository for stack projects
• Setting up validation hooks and scripts
• Bootstrapping a stack project with best practices

Core Principles

This skill follows the GitLab Stack Management patterns:

1. Everything configured through docker-compose.yml and./config
2. Secrets stored in./secrets and Docker secrets
3. docker-entrypoint.sh scripts only when containers don't support native secrets
4. All container files owned by the user running docker (no root-owned files)
5. ./_temporary directory for transient setup files (cleaned up after use)
6. Complete validation before considering stack creation complete

Stack Creation is Complete When

A stack creation is considered COMPLETE only when:

1. ✅ stack-validator skill reports NO issues
2. ✅ secrets-manager skill is satisfied with NO open issues
3. ✅ docker-validation skill is satisfied with NO issues
4. ✅ All validation scripts execute successfully
5. ✅ Git repository is properly initialized and configured
6. ✅ Documentation is complete in./docs

IMPORTANT: NEVER use workarounds. If the direct approach is not working, STOP and ask the user what to do instead.

Stack Creation Workflow

Phase 1: Project Initialization

1.1 Gather Requirements

Ask the user:

• Project name
• Primary services needed (nginx, PostgreSQL, Redis, etc.)
• Remote git repository URL (if any)
• Environment (development, staging, production)
• Special requirements

NEVER assume - always ask if information is missing.

1.2 Check Existing Setup

Before creating anything:

• Check if directory already exists
• Check if git repository exists
• Ask user how to proceed if conflicts exist
• NEVER overwrite without explicit permission

Phase 2: Directory Structure Creation

Create the standard directory structure:

project-name/
├── .git/                       # Git repository
│   ├── hooks/                  # Git hooks (validation scripts)
│   └── config                  # Git configuration
├── config/                     # Service configurations
│   ├── nginx/                  # Nginx configs (if needed)
│   ├── postgres/               # PostgreSQL configs (if needed)
│   └── redis/                  # Redis configs (if needed)
├── secrets/                    # Docker secrets files
│   └── .gitkeep               # Keep directory in git
├── _temporary/                 # Temporary files (gitignored)
├── scripts/                    # Validation and utility scripts
│   ├── pre-commit              # Pre-commit validation hook
│   ├── validate-stack.sh       # Full stack validation
│   └── setup-hooks.sh          # Hook installation script
├── docs/                       # Project documentation
│   ├── decisions/              # Architecture decision records
│   ├── setup.md                # Setup instructions
│   └── services.md             # Service documentation
├── docker-compose.yml          # Main compose file
├── .env.example                # Environment template
├── .gitignore                  # Git exclusions
├── .dockerignore               # Docker exclusions
├── CLAUDE.md                   # Claude Code instructions
└── README.md                   # Project overview

Actions:

1. Create directories: mkdir -p config secrets _temporary scripts docs/decisions
2. Create placeholder files: touch secrets/.gitkeep
3. Set proper permissions: chmod 700 secrets

Phase 3: Git Repository Setup

3.1 Initialize or Connect Repository

If NO git repository exists:

• Strongly suggest creating a local repository
• Ask if remote repository should be added
• Initialize with git init
• Set main as default branch: git config init.defaultBranch main

If remote repository URL provided:

• Clone repository: git clone <url> <project-name>
• Or add remote: git remote add origin <url>
• Verify remote connection: git remote -v

If setup fails: STOP and ask user for guidance. NEVER attempt workarounds.

3.2 Configure Git

Set required git configuration:

# Set main as branch name
git config init.defaultBranch main

# Set ff-only merge strategy
git config pull.ff only
git config merge.ff only

# Ensure no rebase by default
git config pull.rebase false

# Set user info if not set globally
git config user.name "User Name"
git config user.email "user@example.com"

If configuration fails: Ask user to set configuration manually or provide correct values.

3.3 Create.gitignore

Generate comprehensive.gitignore:

# Secrets - NEVER commit
secrets/*
!secrets/.gitkeep
*.key
*.pem
*.crt
*.p12
*.pfx

# Environment files
.env
.env.local
.env.*.local

# Temporary files
_temporary/
*.tmp
*.temp
.cache/

# Docker
.docker/

# IDE
.vscode/
.idea/
*.swp
*.swo
*~

# OS
.DS_Store
Thumbs.db
*.log

# Backup files
*.bak
*.backup

3.4 Create.dockerignore

Generate.dockerignore:

.git
.gitignore
README.md
docs/
_temporary/
*.md
.env
.env.example
secrets/
.vscode/
.idea/

Phase 4: Validation Scripts Setup

4.1 Create scripts/validate-stack.sh

Generate comprehensive validation script that:

• Calls stack-validator skill
• Calls secrets-manager skill validation
• Calls docker-validation skill
• Reports all issues
• Returns exit code 0 only if all pass

Template:

#!/usr/bin/env bash
set -euo pipefail

echo "=== GitLab Stack Validation ==="
echo

# Colors for output
RED='\033[0;31m'
GREEN='\033[0;32m'
YELLOW='\033[1;33m'
NC='\033[0m' # No Color

ERRORS=0

echo "1. Validating stack structure..."
if ! claude-code-cli run stack-validator; then
    echo -e "${RED}✗ Stack validation failed${NC}"
    ((ERRORS++))
else
    echo -e "${GREEN}✓ Stack validation passed${NC}"
fi
echo

echo "2. Validating secrets configuration..."
if ! claude-code-cli run secrets-manager --validate; then
    echo -e "${RED}✗ Secrets validation failed${NC}"
    ((ERRORS++))
else
    echo -e "${GREEN}✓ Secrets validation passed${NC}"
fi
echo

echo "3. Validating Docker configuration..."
if ! claude-code-cli run docker-validation; then
    echo -e "${RED}✗ Docker validation failed${NC}"
    ((ERRORS++))
else
    echo -e "${GREEN}✓ Docker validation passed${NC}"
fi
echo

if [ $ERRORS -gt 0 ]; then
    echo -e "${RED}Validation failed with $ERRORS error(s)${NC}"
    exit 1
fi

echo -e "${GREEN}All validations passed!${NC}"
exit 0

Make executable: chmod +x scripts/validate-stack.sh

4.2 Create scripts/pre-commit

Generate pre-commit hook:

#!/usr/bin/env bash
set -euo pipefail

echo "Running pre-commit validation..."

# Check for secrets in staged files
if git diff --cached --name-only | grep -qE "secrets/.*[^.gitkeep]|\.env$"; then
    echo "ERROR: Attempting to commit secrets or .env file!"
    echo "Secrets should never be committed to git."
    exit 1
fi

# Check for root-owned files
if find . -user root -not -path "./.git/*" 2>/dev/null | grep -q .; then
    echo "ERROR: Root-owned files detected!"
    echo "All files should be owned by the user running Docker."
    exit 1
fi

# Run quick validation (if available)
if [ -x "./scripts/validate-stack.sh" ]; then
    echo "Running stack validation..."
    if ! ./scripts/validate-stack.sh; then
        echo "ERROR: Stack validation failed!"
        echo "Fix issues before committing, or use 'git commit --no-verify' to skip."
        exit 1
    fi
fi

echo "Pre-commit validation passed!"
exit 0

Make executable: chmod +x scripts/pre-commit

4.3 Create scripts/setup-hooks.sh

Generate hook installation script:

#!/usr/bin/env bash
set -euo pipefail

echo "Installing git hooks..."

# Check if .git directory exists
if [ ! -d ".git" ]; then
    echo "ERROR: Not a git repository!"
    exit 1
fi

# Install pre-commit hook
if [ -f "scripts/pre-commit" ]; then
    cp scripts/pre-commit .git/hooks/pre-commit
    chmod +x .git/hooks/pre-commit
    echo "✓ Installed pre-commit hook"
else
    echo "✗ scripts/pre-commit not found"
    exit 1
fi

echo "Git hooks installed successfully!"

Make executable: chmod +x scripts/setup-hooks.sh

After creating scripts: Run ./scripts/setup-hooks.sh to install hooks.

Phase 5: Docker Configuration

5.1 Create docker-compose.yml Template

Generate initial docker-compose.yml based on user requirements:

IMPORTANT: Use the docker-validation skill to ensure the docker-compose.yml follows all best practices.

Basic template structure:

services:
  # Services will be added based on requirements

  # Example: nginx service
  nginx:
    image: nginx:alpine
    container_name: ${PROJECT_NAME:-project}_nginx
    restart: unless-stopped
    ports:
      - "${NGINX_PORT:-80}:80"
    volumes:
      - ./config/nginx:/etc/nginx/conf.d:ro
    networks:
      - app-network

networks:
  app-network:
    driver: bridge

# Secrets will be defined here when needed
secrets: {}

# Volumes for persistent data
volumes: {}

Actions:

1. Generate docker-compose.yml with selected services
2. Use docker-validation skill to validate
3. Fix any issues reported
4. NEVER proceed if validation fails - ask user for guidance

5.2 Create.env.example

Generate environment template:

# Project Configuration
PROJECT_NAME=myproject

# Service Ports
NGINX_PORT=80
# Add more as needed

# Database Configuration (if applicable)
# POSTGRES_PORT=5432
# REDIS_PORT=6379

# IMPORTANT: Copy this file to .env and configure for your environment
# .env is gitignored and should contain actual secrets

Phase 6: Configuration Files

Use the config-generator skill to create service-specific configuration files:

Actions:

1. For each service (nginx, PostgreSQL, Redis), invoke config-generator
2. Generate configs in./config//
3. Validate generated configs with config-generator validation
4. NEVER proceed with invalid configs - ask user for guidance

Example invocation:

• "Generate nginx production configuration for this stack"
• "Create PostgreSQL development configuration"
• "Generate Redis configuration with persistence"

Phase 7: Secrets Management

Use the secrets-manager skill to set up secrets:

Actions:

1. Identify services that require secrets
2. Use secrets-manager to create secure secrets
3. Configure docker-compose.yml with secret references
4. Generate docker-entrypoint.sh scripts ONLY if containers don't support native Docker secrets
5. Validate with secrets-manager that NO secrets are in.env or docker-compose.yml environment
6. NEVER proceed if secrets-manager reports issues - ask user for guidance

Example invocation:

• "Set up database password secret for PostgreSQL"
• "Create Redis password secret"
• "Generate secure random secret for JWT_SECRET"

Phase 8: Documentation Generation

8.1 Create docs/setup.md

Generate setup documentation:

# Setup Instructions

## Prerequisites

- Docker Engine 20.10+
- Docker Compose V2
- Git

## Initial Setup

1. Clone the repository:

git clone <repository-url> cd <project-name>

1. Copy environment template: `cp.env.example.env`
2. Configure environment:
  - Edit.env with your settings
  - NEVER commit.env to git
3. Set up secrets:
  - Follow secrets/README.md for secret creation
  - Use `docker secret create` for each secret
4. Install git hooks: `./scripts/setup-hooks.sh`
5. Validate stack: `./scripts/validate-stack.sh`
6. Start services: `docker compose up -d`

## Validation

Always run validation before deploying:

./scripts/validate-stack.sh

This checks:

- Stack structure
- Secrets configuration
- Docker configuration
- File ownership
- Git exclusions

8.2 Create docs/services.md

Document all services:

# Services Documentation

## Service Overview

| Service | Port | Purpose | Configuration |
|---------|------|---------|---------------|
| nginx | 80 | Web server | ./config/nginx |
| ... | ... | ... | ... |

## Service Details

### Nginx

**Image**: nginx:alpine
**Purpose**: Web server and reverse proxy
**Configuration**: ./config/nginx/
**Secrets**: None
**Volumes**:
- ./config/nginx:/etc/nginx/conf.d:ro

### [Other Services]

Document each service similarly...

8.3 Create docs/decisions/0001-stack-architecture.md

Create architecture decision record:

# 1. Stack Architecture

**Date**: YYYY-MM-DD

## Status

Accepted

## Context

This project uses GitLab Stack Management patterns to ensure:
- Consistent configuration management
- Secure secrets handling
- Proper file ownership
- Validated deployments

## Decision

We will follow these principles:
1. All configuration in docker-compose.yml and ./config
2. All secrets in ./secrets and Docker secrets
3. docker-entrypoint.sh only when necessary
4. No root-owned files
5. ./_temporary for transient files
6. Complete validation before deployment

## Consequences

**Positive**:
- Consistent structure across all stacks
- Automated validation prevents issues
- Secure by default
- Easy to maintain and update

**Negative**:
- Initial setup requires more steps
- Must follow strict patterns
- Validation gates can slow rapid iteration

## Compliance

- stack-validator: Ensures structure compliance
- secrets-manager: Ensures secure secrets
- docker-validation: Ensures Docker best practices

8.4 Create CLAUDE.md

Generate Claude Code instructions for the project:

# CLAUDE.md

This file provides guidance to Claude Code when working with this stack project.

## Project Structure

This is a GitLab Stack project following strict patterns:
- Configuration: docker-compose.yml and ./config/
- Secrets: ./secrets/ and Docker secrets
- Temporary: ./_temporary/ (gitignored)
- Documentation: ./docs/
- Validation: ./scripts/

## Required Skills

This project uses these Claude Code skills:
- **stack-validator**: Validate entire stack structure
- **secrets-manager**: Manage Docker secrets securely
- **docker-validation**: Validate Docker configurations
- **config-generator**: Generate service configs

## Git Configuration

**Branch**: main
**Merge Strategy**: ff-only (fast-forward only)
**Hooks**: Pre-commit validation enabled

## Validation Requirements

BEFORE any git commit, ALL these must pass:
1. stack-validator reports NO issues
2. secrets-manager is satisfied
3. docker-validation is satisfied
4. No root-owned files exist
5. No secrets in .env or docker-compose.yml environment

## Making Changes

### Adding a Service

1. Update docker-compose.yml
2. Use config-generator to create configs
3. Use secrets-manager to handle secrets
4. Run ./scripts/validate-stack.sh
5. Fix ALL issues before committing
6. NEVER commit if validation fails

### Modifying Configuration

1. Edit configuration files
2. Validate with docker-validation
3. Run ./scripts/validate-stack.sh
4. Fix ALL issues before committing

### Working with Secrets

1. Use secrets-manager for ALL secret operations
2. NEVER put secrets in .env or docker-compose.yml
3. Use Docker secrets or ./secrets/ directory
4. Validate with secrets-manager before committing

## Commit Standards

**Pre-commit Hook**: Automatically validates before commit
**Skip Hook**: `git commit --no-verify` (emergency only)
**Commit Messages**: Use conventional commits format

Example:

feat: add Redis service with persistence fix: correct nginx proxy configuration docs: update setup instructions

## Important Rules

1. NEVER commit secrets to git
2. NEVER create root-owned files
3. NEVER skip validation without asking
4. NEVER use workarounds - ask user instead
5. ALWAYS run validation before committing
6. ALWAYS document decisions in ./docs/decisions/
7. ALWAYS use ff-only merge strategy
8. ALWAYS use main as branch name

## Troubleshooting

### Validation Fails

1. Review validation output
2. Use respective skill to investigate (stack-validator, secrets-manager, docker-validation)
3. Fix reported issues
4. Re-run validation
5. Ask user if stuck - NEVER use workarounds

### Git Conflicts

1. NEVER use rebase without explicit permission
2. Use ff-only merges
3. Ask user how to resolve conflicts

### Permission Issues

1. Check file ownership: `find . -user root`
2. Fix with: `sudo chown -R $USER:$USER .`
3. Validate with stack-validator

Phase 9: Final Validation

9.1 Run Complete Validation

Execute full validation workflow:

# Run validation script
./scripts/validate-stack.sh

This must check:

1. stack-validator: Full structure validation
2. secrets-manager: All secrets properly configured
3. docker-validation: Docker configs valid
4. File ownership: No root-owned files
5. Git setup: Proper.gitignore, hooks installed

9.2 Verification Checklist

Manually verify:

• All directories created
• Git repository initialized
• Git configured (main branch, ff-only)
• .gitignore and.dockerignore created
• Validation scripts created and executable
• Git hooks installed
• docker-compose.yml created and valid
• .env.example created
• Service configs generated (if applicable)
• Secrets properly configured (if applicable)
• All documentation created
• CLAUDE.md created
• README.md created
• stack-validator: ✓ NO issues
• secrets-manager: ✓ NO issues
• docker-validation: ✓ NO issues

9.3 Complete Stack Creation

ONLY mark stack creation as complete when:

• All validation passes with NO errors
• All documentation is complete
• Git repository is properly configured
• User confirms everything is correct

If ANY validation fails:

1. Report the issue clearly
2. Ask user how to proceed
3. NEVER use workarounds
4. Fix the issue properly
5. Re-validate

Phase 10: Initial Commit

Once all validation passes:

# Stage all files
git add .

# Commit (pre-commit hook will validate)
git commit -m "feat: initial stack setup

- Created directory structure
- Configured git with main branch and ff-only
- Set up validation scripts and hooks
- Generated docker-compose.yml
- Created service configurations
- Set up secrets management
- Added comprehensive documentation"

# Push to remote (if configured)
git push -u origin main

If commit fails due to pre-commit hook:

1. Review validation output
2. Fix issues
3. Re-run validation
4. Try commit again
5. Ask user if issues persist

Communication Style

When creating a stack:

• Ask clarifying questions for missing information
• Explain each phase before executing
• Report validation results clearly
• NEVER proceed if validation fails
• Ask user for guidance when stuck
• Confirm important decisions before executing

- Redis (port 6379, password in Docker secret)

Next steps:
1. Review secrets in ./secrets/
2. Customize .env from .env.example
3. Run: docker compose up -d"

Summary

The stack-creator skill:

1. Integrates with stack-validator, secrets-manager, docker-validation, config-generator
2. Enforces complete validation before considering creation complete
3. NEVER uses workarounds - always asks user for guidance
4. Configures git properly (main branch, ff-only merges)
5. Installs validation hooks and scripts
6. Documents everything in./docs/
7. Creates production-ready stacks following GitLab Stack Management patterns

Stack creation is complete ONLY when all three validators pass with NO issues and all documentation is in place.
