fabric-operator

fabric-operator is an open-source, cloud-native Operator for managing Hyperledger Fabric networks on Kubernetes. The operator follows the CNCF Operator Pattern, reducing the minutia of performing repetitive, detailed configuration tasks to automated activities performed under the guidance of software-based controllers.

Using the operator, a Fabric network is realized in a declarative fashion by applying a series of CA, Peer, Orderer, and Console resources to the Kubernetes API. In turn, the controller executes a reconciliation loop, orchestrating containers, storage, and configuration to achieve the desired target state.

In nautical terms, fabric-operator serves as the eXecutive Officer / XO of a vessel. It allows you, the captain, to invest valuable time and energy formulating strategic objectives for a blockchain deployment. The operator, or XO, is responsible to enact the plan, and "make it so."

Fabric, Ahoy!
