Kubitter

Kubitter is a fictional open-source project used in tutorials to illustrate how a microblogging-style application could be deployed and managed on Kubernetes. It provides a lightweight, Twitter-like interface for posting short updates about workloads, deployments, and cluster events, aimed at developers and operators.

Architecture and components: The project comprises a backend API, a single-page web client, and optional components such as an authentication service and a Kubernetes operator for automated lifecycle management. The backend exposes REST endpoints for posts, timelines, and user management, while the frontend consumes these endpoints. Data is stored in a relational database, with subscribers and relationships modeled in the schema. Security is designed around OAuth2 or token-based authentication, integrated with Kubernetes RBAC for access control.

Deployment and operation: Kubitter is designed to run inside a Kubernetes cluster. It provides Helm charts and Kubernetes manifests for deployment, including deployment, service, ingress, and persistent storage configuration. An optional operator can reconcile cluster resources and auto-scale services based on workload. The project emphasizes GitOps-friendly practices with Helm-based releases and compatibility with Argo CD or Flux workflows.

Features and usage: Typical features include posting short updates, following other users, liking posts, and searching timelines. Real-time updates may be implemented via WebSockets or long-polling in the frontend. The project includes example dashboards for monitoring health and basic audit logs, highlighting common patterns in cloud-native deployments.

Notes: Kubitter is not a real project; it exists as a hypothetical example used to discuss deployment patterns, microservice design, and user interfaces in Kubernetes contexts.
