In this tutorial, we will learn how to build and deploy a conversational chatbot using Google Cloud Run and Dialogflow. This chatbot will provide responses to user queries on a specific topic, such as weather information, customer support, or any other domain you choose. We will cover the steps from creating the Dialogflow agent to deploying the webhook service on Google Cloud Run.
A Google Cloud Platform (GCP) account.
Basic knowledge of Python programming.
Familiarity with Google Cloud Console.
Step 1: Set Up Dialogflow Agent
Create a Dialogflow Agent: Log into the Dialogflow Console (Google Dialogflow). Click on “Create Agent” and fill in the agent details. Select the Google Cloud Project you want to associate with this agent.
Define Intents: Intents classify the user’s intentions. For each intent, specify examples of user phrases and the responses you want Dialogflow to provide. For example, for a weather chatbot, you might create an intent named “WeatherInquiry” with user phrases like “What’s the weather like in Dallas?” and set up appropriate responses.
Step 2: Develop the Webhook Service
The webhook service processes requests from Dialogflow and returns dynamic responses. We’ll use Flask, a lightweight WSGI web application framework in Python, to create this service.
