cosmos-operator
A Kubernetes operator for deploying and managing highly-available Cosmos SDK blockchain nodes and supporting chains like Penumbra.
What is cosmos-operator?
Cosmos Operator is a Kubernetes Operator that automates the deployment and management of blockchain nodes built with the Cosmos SDK and other CometBFT-based chains like Penumbra. It provides Custom Resource Definitions (CRDs) to define node configurations as YAML files, enabling highly-available, fault-tolerant infrastructure with minimal manual oversight. The tool solves the complexity of manually orchestrating blockchain nodes in Kubernetes by applying the operator pattern to capture domain-specific operational knowledge.
DevOps engineers, SREs, and blockchain infrastructure teams who manage Cosmos SDK-based blockchain nodes in Kubernetes environments and want to automate node lifecycle management. It's also for organizations running validator sentries, RPC nodes, or seed nodes that require production-grade reliability and scalability.
Developers choose Cosmos Operator because it provides a specialized, production-tested solution for Cosmos ecosystem nodes, going beyond generic Kubernetes StatefulSets by offering chain-specific features like scheduled upgrades, automatic PVC resizing, and support for validator sentry configurations. Its deep integration with Cosmos SDK conventions and support for tools like horcrux and heighliner images reduces operational overhead compared to manual or generic orchestration approaches.
