A Kubernetes operator that provides unified APIs to manage multiple database and streaming systems like MySQL, PostgreSQL, Redis, and Kafka.
KubeBlocks is a Kubernetes operator that provides a unified control plane to manage multiple types of databases and streaming systems within Kubernetes environments. It solves the problem of needing to learn and maintain separate operators for each database by offering a single set of APIs and code to handle lifecycle management and day-2 operations for engines like MySQL, PostgreSQL, Redis, MongoDB, and Kafka.
Platform engineers, DevOps teams, and developers who deploy and manage multiple stateful data engines (databases, caches, message queues) on Kubernetes and want to reduce operational complexity and learning curves.
Developers choose KubeBlocks because it replaces the need for multiple dedicated database operators with a single, unified solution that supports over 35 engine types, offers production-grade reliability and observability, and simplifies day-2 operations through consistent declarative APIs and a powerful CLI tool.
KubeBlocks is a Kubernetes Operator designed to manage a variety of databases and streaming systems, including MySQL, PostgreSQL, MongoDB, Redis, RabbitMQ, RocketMQ, and more, within Kubernetes environments.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Abstracts diverse databases into a single set of CRDs, supporting over 35 engines like MySQL, Redis, and Kafka through one API, reducing operator sprawl and learning curves.
Adopted by large enterprises in finance and telecom, with features for high-availability integrations (e.g., Orchestrator, Patroni) and comprehensive backup/recovery options.
Provides consistent tools for scaling, upgrades, and monitoring across all engines via declarative APIs and the interactive kbcli tool, easing maintenance.
Allows integration of new database engines through addons, currently extending to vector databases and data warehouses, with community-driven contributions.
Labeled as alpha in badges, indicating potential API instability and breaking changes that could disrupt production deployments, as noted in the project status.
Licensed under AGPL v3, which imposes copyleft requirements that may complicate use in proprietary or closed-source commercial environments.
Tightly coupled with Kubernetes, making it irrelevant for non-K8s setups and adding dependency on Kubernetes expertise and infrastructure.
