peitho

Peitho - Hyperledger Fabric chaincode Cloud-native managed system

The chaincode of Hyperledger Fabric can be handed over to k8s for management, which is suitable for deploying the Hyperledger Fabric alliance chain on k8s, and solves the problem of chaincode being free from k8s control.

简体中文

Features

• K8s fully managed chaincode
• There is no intrusion to the fabric, just configure the CORE_VM_ENDPOINT environment variable to Peitho service.
• Support fabric 1.4.x 2.0 and above

kubectl apply -f peitho-deployment.yaml

1. change peer env

- name: CORE_VM_ENDPOINT
  value: tcp://peitho:8080
