Tutorial: Integrate GitLab Merge Request approvals with external systems

This post details the deployment of a demo application that integrates with GitLab's External Status Check feature. It outlines the steps to deploy the application to Kubernetes, configure it with a GitLab token, and set up the status check within a GitLab project. The application receives API calls from merge requests, stores them in a database, and provides an interface for external approval/rejection, which then updates the merge request status. Debugging tips for pod logs and database access are also provided.
