feng yang : https://github.com/hyperledger/cello/issues/602
Yuanmao Zhu : python lib for fabric cli call, change backend to plugin(RPC Call with Go), FE → BE(business logic, Django) → RPC Server(Go, SDK server, use RESTful API first) → fabric cli call(Go pkg).
feng yang and Xichen Pan + haoyu li are absent today.
Xichen Pan : working with Xiao Ran for the install issue: https://github.com/hyperledger/cello/issues/621. Run commands with peer cli.
Xiao Ran : Reading BE code. Chaincode v2 API Spec. Check the Approve API, learn to run fabric peer client.
- Install still has issues, will recheck. Xichen Pan help. Fixed node version, django dependency issue.
~~Welcome~~ ~~Haibo Yang and haoyu li : create wiki account, join github id to hyperledger team → cello org. https://github.com/hyperledger/cello~~
~~LFDT is revising the charter for each project. Please help review and see if there's any comment:~~
feng yang suggest revise the creating peer node API:
- Only create one peer with the specified name
- Yuanmao Zhu will help fix the issue
feng yang suggests:
- When downloading channel config, remove the hint of downloading succeed
- When creating channel, no need to edit orderer nodes
- When updating the channel (add an org), why need to input the msp_id? Need to update the steps into docs.
Haibo Yang Intern plan: Project Plan - Decentralized Blockchain Network Operation Dashboard
- Docker image for HLF v2.5 (latest is v2.5.9): update all required images
- https://github.com/hyperledger/cello/pull/627: Suggest upgrade node.js to 20+, lots of changes are needed. https://github.com/hyperledger/cello/pull/628
  - The https://www.npmjs.com/package/netlify-lambda is deprecated, need to replace to https://github.com/netlify/cli.
haoyu li 2nd year master of UIUC, still reading the docs.
- Hyperledger Fabric, Cello (create, operate, use)
New Fabric Cli RPC Server Yuanmao Zhu : Use restful API first (to replace the rpc call, which is good for large-scale)
- arch: https://excalidraw.com/#json=KOxuJqTyxXY2cpuFHDnFj,qJqkiXqeu38C4u2-zms-1w
- requirement:
  - api-engine client - RPC Server communication
  - lib: gRPC
  - API design
  - Container config
  - Todo: check different SDKs and decide language for the server
- Questions:
  - API Engine can use restful API to call the fabric operator?
  - The operator will use which SDK?
Others
- TODO: update HLF version from 2.2 LTS → 2.5 LTS
  - HLF 2.5.0 is released.
- TODO: integrate hlf-operator into Cello as the k8s agent.
  - feng yang mentioned that the release-0.9.0-h3c branch may contain some k8s APIs and code
