How to Deploy a LangGraph App on Google Cloud Platform (GCP) | Step-by-Step Guide

Описание: In this video, I walk you through deploying a LangGraph application on Google Cloud Platform (GCP) from start to finish. I cover key setup steps, including:

✅ Addressing LangGraph's hosting challenges (requires a paid LangSmith account)
✅ Setting up a Self-Hosted Lite deployment to run on GCP
✅ Configuring Docker images for deployment
✅ Setting up Postgres (Cloud SQL) and Redis (Memorystore for Redis) in GCP
✅ Creating a Virtual Private Cloud (VPC) for secure networking
✅ Building and pushing a Docker image using the LangGraph CLI to Google Artifact Registry
✅ Deploying the application on Cloud Run with proper VPC connectors and Cloud Build triggers

I also ensure the app runs locally before deploying and walk through troubleshooting steps and final validation via LangGraph Studio.
