如何在config.yml文件中配置多个生产分支？

production:
  server:
    host: example.com
    port: 22
    username: admin
    password: password123
  database:
    type: mysql
    host: db.example.com
    port: 3306
    username: dbadmin
    password: dbpassword123
  deploy:
    path: /var/www/html
    version_control: git
    deploy_script: deploy.sh

production2:
  server:
    host: example2.com
    port: 22
    username: admin2
    password: password456
  database:
    type: postgresql
    host: db2.example.com
    port: 5432
    username: dbadmin2
    password: dbpassword456
  deploy:
    path: /var/www/html2
    version_control: svn
    deploy_script: deploy2.sh
