This project leverages K8S features to run a various-functioned chatbot system, which includes member signup, member authentication, pushing messages to members regularly.

I wrote a blog post about this project in Chinese, and here is link.

Flow chart

• User is required to signup through Register frontend and Register backend
• Register backend stores user's information to database through Users API
• User sends message via LINE App which sends a webhook event to our Webhook service
• Webhook handles webook events from LINE and authenticates with Users API
• CronJob executes pushing messages scripts regularly
