生产部署

部署 Potato 用于多用户生产环境标注。

生产部署

为多用户、数据持久化和适当安全性的真实标注任务部署 Potato。

服务器配置

基本生产配置

yaml
server:
  host: 0.0.0.0
  port: 8000
  workers: 4
  timeout: 120

使用 HTTPS

用于安全连接（生产环境推荐）：

yaml
server:
  host: 0.0.0.0
  port: 443
  ssl:
    cert: /path/to/cert.pem
    key: /path/to/key.pem

使用 Gunicorn 运行

为了更好的性能和可靠性：

bash
gunicorn "potato.server:create_app('config.yaml')" \
  --workers 4 \
  --bind 0.0.0.0:8000 \
  --timeout 120

带 SSL

bash
gunicorn "potato.server:create_app('config.yaml')" \
  --workers 4 \
  --bind 0.0.0.0:443 \
  --certfile /path/to/cert.pem \
  --keyfile /path/to/key.pem

反向代理设置

Nginx 配置

nginx
upstream potato {
    server 127.0.0.1:8000;
}
 
server {
    listen 80;
    server_name annotation.example.com;
    return 301 https://$server_name$request_uri;
}
 
server {
    listen 443 ssl;
    server_name annotation.example.com;
 
    ssl_certificate /etc/letsencrypt/live/annotation.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/annotation.example.com/privkey.pem;
 
    location / {
        proxy_pass http://potato;
        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;
    }
 
    # Increase timeouts for long annotation sessions
    proxy_read_timeout 300;
    proxy_connect_timeout 300;
    proxy_send_timeout 300;
}

Apache 配置

apache
<VirtualHost *:443>
    ServerName annotation.example.com
 
    SSLEngine on
    SSLCertificateFile /path/to/cert.pem
    SSLCertificateKeyFile /path/to/key.pem
 
    ProxyPreserveHost On
    ProxyPass / http://127.0.0.1:8000/
    ProxyPassReverse / http://127.0.0.1:8000/
 
    <Proxy *>
        Order allow,deny
        Allow from all
    </Proxy>
</VirtualHost>

Docker 部署

Dockerfile

dockerfile
FROM python:3.10-slim
 
WORKDIR /app
 
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
 
COPY . .
 
EXPOSE 8000
 
CMD ["gunicorn", "potato.server:create_app('config.yaml')", \
     "--workers", "4", "--bind", "0.0.0.0:8000"]

Docker Compose

yaml
version: '3.8'
 
services:
  potato:
    build: .
    ports:
      - "8000:8000"
    volumes:
      - ./data:/app/data
      - ./annotations:/app/annotations
    environment:
      - POTATO_DEBUG=false
    restart: unless-stopped
 
  nginx:
    image: nginx:alpine
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - ./nginx.conf:/etc/nginx/nginx.conf
      - ./certs:/etc/ssl/certs
    depends_on:
      - potato
    restart: unless-stopped

用户认证

受限访问

yaml
allow_all_users: false
authorized_users:
  - user1@example.com
  - user2@example.com
  - user3@example.com

管理员访问

yaml
admin_users:
  - admin@example.com
 
admin_dashboard:
  enabled: true
  path: /admin

会话管理

yaml
session:
  secret_key: "your-secure-secret-key-here"
  timeout: 3600  # 1 hour
  secure_cookie: true  # Requires HTTPS

数据持久化

基于文件的存储

yaml
output:
  path: /var/potato/annotations/
  format: json
  backup_interval: 3600  # Hourly backups

数据库后端

对于更大规模的部署，使用 MySQL：

yaml
database:
  type: mysql
  host: localhost
  port: 3306
  name: potato_db
  user: potato
  password: ${DB_PASSWORD}  # Use environment variable

详见 MySQL 后端。

监控

健康检查端点

yaml
monitoring:
  health_check: /health
  metrics: /metrics

日志配置

yaml
logging:
  level: INFO
  file: /var/log/potato/app.log
  max_size: 100MB
  backup_count: 5
  format: "%(asctime)s - %(name)s - %(levelname)s - %(message)s"

Prometheus 指标

yaml
monitoring:
  prometheus:
    enabled: true
    port: 9090

扩展

水平扩展

用于高流量部署：

yaml
# docker-compose.yml
services:
  potato:
    deploy:
      replicas: 3
    # ... rest of config
 
  nginx:
    # Load balancer
    volumes:
      - ./nginx-lb.conf:/etc/nginx/nginx.conf

负载均衡配置

nginx
upstream potato_cluster {
    least_conn;
    server potato_1:8000;
    server potato_2:8000;
    server potato_3:8000;
}

备份策略

自动备份

bash
#!/bin/bash
# backup.sh
DATE=$(date +%Y%m%d_%H%M%S)
BACKUP_DIR=/var/backups/potato
 
# Backup annotations
tar -czf $BACKUP_DIR/annotations_$DATE.tar.gz /var/potato/annotations/
 
# Backup config
cp /var/potato/config.yaml $BACKUP_DIR/config_$DATE.yaml
 
# Keep only last 7 days
find $BACKUP_DIR -mtime +7 -delete

添加到 crontab：

bash
0 2 * * * /var/potato/backup.sh

安全检查清单

  • 使用有效 SSL 证书的 HTTPS
  • 设置强会话密钥
  • 使用 authorized_users 限制用户访问
  • 保持 Potato 和依赖更新
  • 对敏感数据使用环境变量
  • 配置防火墙规则
  • 启用日志和监控
  • 设置定期备份
  • 生产环境使用数据库后端
  • 定期检查管理员访问权限

环境变量

bash
# .env file
POTATO_SECRET_KEY=your-super-secret-key
POTATO_DB_PASSWORD=database-password
POTATO_ADMIN_EMAIL=admin@example.com

在 Docker Compose 中加载：

yaml
services:
  potato:
    env_file:
      - .env

故障排除

检查日志

bash
# Gunicorn logs
journalctl -u potato -f
 
# Docker logs
docker-compose logs -f potato

常见问题

502 Bad Gateway：检查 Potato 是否正在运行并绑定到正确的端口

会话问题：确保密钥在重启之间保持一致

性能缓慢：增加 worker 数量或添加数据库后端
