rasax「docker compose」使用模式

Posted on Edited on In

Rasa X 介绍

Rasa X can be used in local mode and in server mode. Rasa X in local mode is helpful for sharing your assistant before you have a server set up. Once your assistant is up and running, you will want to deploy Rasa X to a server so that it’s available 24/7 and everyone on your team can use it to review conversations and annotate new training data.

之前介绍了本地模式，今天来折腾下 docker compose 模式。

要求服务器环境前提安装 python3, docker、docker-compose。

主要四个步骤：

  1. Download
  2. Install
  3. Start
  4. Access

Download

使用 Google Cloud Platform，大家可以搜索下使用方法，我这边主要结合阿里云使用的。

start

就可以创建容器了：

1
docker-compose up -d

access

执行命令：

1
python rasa_x_commands.py create --update admin me <PASSWORD>

好了，利用新密码就可以进入网页了。

总结

其中配置项主要参考官网说的来，这里就不再赘述了。
