This repository serves as a curated collection of software packages for Kubernetes application deployment and package management. Its primary purpose is to provide a standardized set of predefined application configurations to ensure consistent software installations across different clusters. The project focuses on maintaining version compatibility and providing a reliable source of verified packages. This allows for a standardized cluster setup by simplifying the installation and versioning of software on a container orchestration platform.

Redis is a high-performance in-memory key-value store that functions as a distributed cache, message broker, and NoSQL database. It provides sub-millisecond read and write access to data stored in RAM and can operate as a vector database for indexing high-dimensional embeddings. The system supports a wide range of data storage and synchronization primitives, including the management of strings, hashes, lists, sets, and JSON documents. It enables real-time data operations through atomic transactions, hybrid persistence using snapshots and append-only logs, and high-availability configurations

This is a Raft consensus library and distributed consensus engine implemented in Go. It provides the primitives necessary to build fault-tolerant distributed services by implementing a replicated state machine that ensures a group of servers agree on a shared system state through leader election and log replication. The project distinguishes itself through a pluggable architecture for storage backends and snapshot storage, decoupling the consensus logic from physical persistence. It includes specialized mechanisms for leadership transfer, protocol version management to support rolling upgrade

Flux is a Kubernetes GitOps delivery tool used to automate application deployments by synchronizing cluster state with configurations stored in Git, OCI, or Helm repositories. It functions as a set of controllers that monitor desired state in external sources and continuously reconcile the live cluster to match those definitions. The system distinguishes itself through a multi-cluster management plane that coordinates application delivery across fleets of remote clusters from a central hub. It provides a dedicated mechanism for automated image updates, which scans container registries for new

k3sup is a command-line tool that installs and manages lightweight Kubernetes clusters entirely over SSH, without requiring any pre-installed software on the target machines. It bootstraps clusters on remote hosts using a single statically-linked binary, then provides immediate kubectl access by fetching and merging the cluster's admin credentials into the local configuration. The tool supports plan-driven cluster topology, allowing users to define node roles and configuration in a YAML file for automated multi-node deployment. The tool distinguishes itself by enabling parallel execution of i

Flux is a Kubernetes GitOps controller and deployment engine that synchronizes cluster state with configurations stored in a Git repository. It serves as a system for continuous delivery, utilizing a manifest generator to create configuration files from templates and a reconciliation loop to ensure the live environment matches the desired state defined in versioned repositories. The project distinguishes itself through a container image automator that scans registries and updates manifests based on semantic versioning or regular expressions. It incorporates secure configuration deployment via

The CNCF Curriculum is an open-source repository that organizes exam domains and learning paths for CNCF certification courses covering Kubernetes and cloud-native technologies. It structures certification content into weighted domains that reflect exam question distribution, providing a structured study guide for candidates preparing for CNCF certifications. The curriculum is organized around multiple cloud-native domains including networking, security, GitOps, platform engineering, and certification preparation. It teaches cloud-native concepts through the lens of building and operating int

Este proyecto es un conjunto de herramientas de despliegue para inicializar y configurar entornos locales de Kubernetes específicamente dentro de Docker Desktop para Mac y Windows. Funciona como un bootstrapper de clúster local que instala componentes esenciales, incluyendo el dashboard de Kubernetes, controladores de ingress y el service mesh Istio. El kit de herramientas incluye un sistema de espejado de imágenes de contenedor que remapea registros a espejos, permitiendo que el entorno evite restricciones de red y acelere la descarga de imágenes durante el proceso de arranque. Las capacidades generales cubren la configuración de entornos de microservicios, incluyendo la configuración de gateways de ingress y la inyección automática de sidecars para la comunicación entre servicios. También proporciona utilidades para gestionar tokens de acceso al clúster y ejecutar comandos dentro de pods activos.

jx es una plataforma de entrega GitOps y orquestador de CI/CD para Kubernetes, diseñado para automatizar la construcción y el despliegue de aplicaciones. Funciona como un gestor de pipelines nativo de la nube que ejecuta secuencias de construcción y despliegue basadas en contenedores utilizando un catálogo de tareas reutilizables. El proyecto se distingue por la orquestación automatizada de entornos de vista previa, que se crean y destruyen según la actividad de las pull requests para permitir la validación antes de fusionar. Emplea un modelo de sincronización de estado basado en GitOps para mantener el estado deseado de los clústeres mediante el sondeo de repositorios git y la aplicación de actualizaciones de configuración verificadas. El sistema cubre una amplia gama de capacidades, incluyendo la gestión de despliegue de Helm charts, la orquestación de múltiples clústeres y la integración con almacenes de secretos externos. También proporciona herramientas de productividad para desarrolladores para la reconstrucción incremental de aplicaciones y la sincronización de código de local a pod. La instalación se gestiona mediante el despliegue del operador git y el arranque de trabajos de clúster para garantizar la consistencia de las herramientas.

Pigsty is a full-stack orchestration suite for deploying, monitoring, and managing high-availability PostgreSQL clusters and their supporting infrastructure. It functions as a cluster management platform and high-availability suite that automates failover, manages virtual IPs, and ensures data consistency through distributed consensus. The project distinguishes itself by providing a comprehensive database infrastructure-as-code framework and a dedicated observability stack. It incorporates a backup and recovery manager supporting point-in-time recovery via S3-compatible object storage, alongs

Cluster API is a declarative framework and multi-cluster management system for automating the creation, scaling, and destruction of Kubernetes clusters across diverse infrastructures. It acts as a cluster provisioning orchestrator and infrastructure provisioner, using a centralized management cluster to operate the full lifecycle of multiple remote workload clusters. The project employs a provider-based plugin architecture that decouples core orchestration logic from specific cloud or bare-metal implementations. This allows the system to standardize the deployment of control planes, the boots

Octelium is a zero-trust network access platform and identity-aware proxy designed to secure private HTTP, SSH, and SQL resources. It functions as a secure gateway that validates human and workload identities using OIDC, SAML, and FIDO2 passkeys before granting access to internal applications and SaaS APIs. The system is distinguished by its secretless access broker, which injects credentials—such as API keys, passwords, and AWS Sigv4 signatures—at the gateway level so users can access databases and cloud resources without managing secrets. It further specializes in AI gateway administration,

This project is a Kubernetes cluster management framework and infrastructure-as-code template designed to bootstrap and maintain Talos Kubernetes clusters on bare-metal or virtual machines.
