Novita 的工作原理

Novita 是一个面向 AI 的无服务器基础设施平台，旨在以低延迟和降低成本来扩展开源模型。它支持数百个生产就绪的模型——包括 Llama、Mistral、Claude 和 Stable Diffusion——并提供优化的 API、按需 GPU 和自定义模型部署，无需任何 DevOps 开销。

​
推荐模型

我们推荐具有 +100k 上下文窗口的优秀编码模型。

​
创建 API 密钥

需要 Novita 账户才能创建 API 密钥。
直接访问 Novita 的 API 密钥页面创建新的 API 密钥。 或者，按照以下步骤操作：
  1. 进入您的 Novita 控制台
  2. 点击”Manage API Keys”按钮或进入您的个人资料图片并点击 API Keys
  3. 点击”Add New Key”并填写’Kodus’或您想要的任何名称
  4. 点击”Confirm”
  5. 复制 API 密钥并将其保存在安全的地方

​
System Requirements

  • Docker (latest stable version) - Node.js (latest LTS version) - Yarn or NPM (latest stable version) - Domain name or fixed IP (for external deployments)
  • 3000: Kodus Web App - 3001: Orchestrator API - 5672, 15672: RabbitMQ - 5432: PostgreSQL - 27017: MongoDB
Internet access is only required if you plan to connect with cloud-based Git services like GitHub, GitLab, or Bitbucket. For self-hosted Git tools within your network, external internet access is optional.

​
Domain Name Setup (Optional)

If you're planning to integrate Kodus with cloud-based Git providers (GitHub, GitLab, or Bitbucket), you'll need public-facing URLs for both the Kodus Web App and its API. This allows your server to receive webhooks for proper Code Review functionality and ensures correct application behavior. We recommend setting up two subdomains:
  • One for the Web Application, e.g., kodus-web.yourdomain.com.
  • One for the API, e.g., kodus-api.yourdomain.com.
Both subdomains should have DNS A records pointing to your server's IP address. Later in this guide, we will configure a reverse proxy (Nginx) to route requests to these subdomains to the correct internal services. This setup is essential for full functionality, including webhooks and authentication.
Note: If you're only connecting to self-hosted Git tools on your network and do not require public access or webhooks, you might be able to use a simpler setup, but this guide focuses on public-facing deployments.

​
Get the Kodus Installer

Clone our installer repository: 
git clone https://github.com/kodustech/kodus-installer.git
cd kodus-installer

​
Configure Environment Variables

First, copy the example environment file: 
cp .env.example .env
Generate secure keys for the required environment variables using: 
# For most security keys
openssl rand -base64 32

# Specifically for API_CRYPTO_KEY and CODE_MANAGEMENT_SECRET
openssl rand -hex 32

# Specifically for CODE_MANAGEMENT_WEBHOOK_TOKEN
openssl rand -base64 32 | tr -d '=' | tr '/+' '_-'
You'll need to generate values for these security keys:
  • WEB_NEXTAUTH_SECRET (use openssl rand -base64 32)
  • WEB_JWT_SECRET_KEY (use openssl rand -base64 32)
  • API_CRYPTO_KEY (use openssl rand -hex 32)
  • API_JWT_SECRET (use openssl rand -base64 32)
  • API_JWT_REFRESHSECRET (use openssl rand -base64 32)
  • CODE_MANAGEMENT_SECRET (use openssl rand -hex 32)
  • CODE_MANAGEMENT_WEBHOOK_TOKEN (use openssl rand -base64 32 | tr -d '=' | tr '/+' '_-')
Never commit your .env file to version control. Keep your API keys and database credentials secure.
Then update your .env file with the following required variables: 
# Core System Settings
WEB_NODE_ENV="self-hosted"                     # Keep as "self-hosted" for self-hosted setup
WEB_HOSTNAME_API="kodus-api.yourdomain.com"    # Public API hostname (e.g., kodus-api.yourdomain.com)
WEB_PORT_API=443                               # Public API port (usually 443 for HTTPS, or 80 if not using SSL yet)
WEB_PORT=3000                                  # Internal Web application port (reverse proxy will handle public port)
GLOBAL_API_CONTAINER_NAME="kodus-orchestrator" # API container name

API_CRYPTO_KEY=                               # Crypto key (generate with: openssl rand -hex 32)
API_JWT_EXPIRES_IN=365d                       # JWT token expiration time
API_JWT_SECRET=                               # JWT secret key

在环境文件中配置 Novita

编辑您的 .env 文件并配置核心设置。对于 LLM 集成，在固定模式下使用 Novita： 
# 核心系统设置（使用您的域名更新）
WEB_HOSTNAME_API="kodus-api.yourdomain.com"
WEB_PORT_API=443
NEXTAUTH_URL="https://kodus-web.yourdomain.com"

# 安全密钥（使用上面的 openssl 命令生成）
WEB_NEXTAUTH_SECRET="your-generated-secret"
WEB_JWT_SECRET_KEY="your-generated-secret"
API_CRYPTO_KEY="your-generated-hex-key"
API_JWT_SECRET="your-generated-secret"
API_JWT_REFRESHSECRET="your-generated-secret"

# 数据库配置
API_PG_DB_PASSWORD="your-secure-db-password"
API_MG_DB_PASSWORD="your-secure-db-password"

# Novita 配置（固定模式）
API_LLM_PROVIDER_MODEL="deepseek-v3-0324"                    # 选择您偏好的模型
API_OPENAI_FORCE_BASE_URL="https://api.novita.ai/v3/openai"  # Novita API URL
API_OPEN_AI_API_KEY="your-novita-api-key"                    # 您的 Novita API 密钥

# Git 提供商 Webhook（选择您的提供商）
API_GITHUB_CODE_MANAGEMENT_WEBHOOK="https://kodus-api.yourdomain.com/github/webhook"
# 或 API_GITLAB_CODE_MANAGEMENT_WEBHOOK="https://kodus-api.yourdomain.com/gitlab/webhook"
# 或 GLOBAL_BITBUCKET_CODE_MANAGEMENT_WEBHOOK="https://kodus-api.yourdomain.com/bitbucket/webhook"
固定模式非常适合 Novita，因为它提供兼容 OpenAI 的 API，并且只需要一个 API 密钥。这大大简化了您的设置。

​
Run the Installation Script

Looking for more control? Check out our docker-compose file for manual deployment options.
Set the proper permissions for the installation script: 
chmod +x scripts/install.sh
Run the script: 
./scripts/install.sh

​
What the Installer Does

Our installer automates several important steps:
  • Verifies Docker installation
  • Creates networks for Kodus services
  • Clones repositories and configures environment files
  • Runs docker-compose to start all services
  • Executes database migrations
  • Seeds initial data
🎉 Success! When complete, Kodus Orchestrator API and Web Application should be running on your machine. You can verify your installation by visiting http://localhost:3000 - you should see the Kodus Web Application interface.
Code Review features will not work yet unless you complete the reverse proxy setup. Without this configuration, external Git providers cannot send webhooks to your instance.

​
6. 设置反向代理（用于生产环境）

对于 Webhook 和外部访问，配置 Nginx： 
# Web 应用（端口 3000）
server {
    listen 80;
    server_name kodus-web.yourdomain.com;
    location / {
        proxy_pass http://localhost:3000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

# API（端口 3001）
server {
    listen 80;
    server_name kodus-api.yourdomain.com;
    location / {
        proxy_pass http://localhost:3001;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

​
验证 Novita 集成

除了基本的安装验证外，确认 Novita 正常工作： 
# 专门验证 Novita API 连接
docker logs kodus-orchestrator-prod | grep -i novita
有关 SSL 设置、监控和高级配置的详细信息，请参阅我们的完整部署指南。

​
故障排除

  • 在 Novita 控制台中验证您的 API 密钥是否正确且处于活动状态
  • 检查您的 Novita 账户中是否有足够的信用额度
  • 确保您的 .env 文件中没有多余的空格
  • 检查配置中的模型名称拼写是否正确
  • 验证该模型在您的 Novita 计划中是否可用
  • 尝试使用我们推荐列表中的其他模型
  • 验证您的服务器是否有互联网访问权限以访问 api.novita.ai
  • 检查是否有任何防火墙限制
  • 查看编排器日志以获取详细的错误消息
