Created by Haitao Yue, last modified by Gari Singh on Sep 17, 2020


Project Health

Now we are re-designing the architecture and rewrite the agent service from docker runner to RESTful API server.

Refine project start shell script, use GUI configuration support, can config the environment for service startup.


The implementation of the new architecture is slow, we need to finish the first demo with docker / k8s restful server agent.


v1.0.0 (In plan)

  • New governing model;
  • Support fabric v1.4 LTS and 2.0 experimentally;
  • K8S / docker RESTful API server agent.

Overall Activity in the Past Quarter

  • Design the new governing model.
  • Completed the new design for the dashboard and initial implementation is also complete.
  • Updated the document for the new architecture.
  • Moved cello build and test onto Azure and optimized the build so that only changed components get build and tested to save resources.

Current Plans

Finish the new dashboard implementation (complete end of this year) High

Add k8s load balancer as a way to expose k8s operator agent created fabric node


API server design and implementation

Support HLF 2.2 LTS and later version (SDK issues on admin capabilities, fallback to CLI?) Medium
