Shell-operator is a tool for running event-driven scripts in a Kubernetes cluster

Agones is a Kubernetes game server orchestrator designed for deploying, scaling, and managing dedicated multiplayer game server processes across a distributed cluster. It provides the core infrastructure needed to provision individual or grouped server processes to support real-time multiplayer gaming sessions. The system includes a fleet manager to automate the lifecycle of server groups based on player demand and a health monitor to track the connectivity and operational status of active processes. It integrates with cluster autoscalers to synchronize server resource requirements with cloud

KubeEdge is a distributed edge computing framework that extends Kubernetes to manage containerized workloads and hardware devices at the edge. It functions as a Kubernetes edge orchestration system, allowing the deployment and management of applications across distributed edge nodes using native Kubernetes APIs and workflows. The project distinguishes itself through a specialized focus on IoT integration and node autonomy. It employs digital-twin state modeling to represent physical hardware devices as virtual objects, utilizing an MQTT-based messaging bus for communication with heterogeneous

Descheduler is a Kubernetes workload rebalancer and pod eviction manager designed to optimize resource distribution and maintain cluster stability. It identifies and removes pods that no longer satisfy scheduling constraints or health requirements, allowing the cluster to relocate them to more suitable nodes. The project provides specialized capabilities for balancing node resource utilization, enforcing topology spread constraints, and removing duplicate pods to improve distribution. It also functions as an autoscaler helper by compacting workloads onto fewer nodes to facilitate the downscal

An opinionated platform engineering roadmap - in the form of a website

DevOps-Roadmap is a comprehensive educational repository and knowledge base designed to guide technical professionals through the complexities of modern software engineering. It functions as a structured curriculum and reference library, covering the full spectrum of skills required to master system architecture, infrastructure management, and cloud operations. The project distinguishes itself by bridging the gap between high-level architectural design and the practical realities of engineering leadership. It provides curated insights into distributed systems, data consistency, and scalable d

OpenCost is an open-source tool for monitoring and allocating Kubernetes and cloud infrastructure costs. It provides real-time visibility into spending by distributing asset costs to workloads based on resource requests and usage, breaking down spend by namespace, deployment, pod, and label. The system functions as both a Kubernetes cost allocation engine and a multi-cloud cost analyzer, ingesting billing data from AWS, Azure, and GCP to present unified cost metrics alongside cluster costs. The tool distinguishes itself through its allocation-based cost model, which compares requested versus

This project is an administrative reference for Docker, providing guides and command references for system maintenance, image building, network configuration, and security hardening. It serves as a comprehensive manual for managing the container lifecycle and performing general system administration. The reference covers the construction and optimization of images through build files, layering strategies, and registry integration. It also provides instructions for configuring isolated virtual networks, mapping ports, and implementing security hardening using Linux capabilities and read-only f
