  • https://github.com/hyperledger/cello/pull/490
  • https://github.com/hyperledger/cello/pull/492
• Release plan 1.0.0-beta1 Q3 of 2022
  
  • user: update (password): 1pw
  • org
  • channel: Yuanmao Zhu
    •  download the config block file (peer channel fetch config businesschannel_cfg.block -c ${APP_CHANNEL} -o orderer:7050). config-export → latest config json file: 2pw
      • TODO: need feng yang to add a download config menu item for the channel.
    • Add new org MSP Json into channel. Yuanmao Zhu https://github.com/hyperledger/cello/pull/490
      
      • TODO: select ApplicationOrg or OrdererOrg
      • This PR is blocked, it is hard to upload a file and add JSON data at the same time.
        May need to refine the design of the request body,
        e.g. copy/paste the config file in plain text format, then send the request in JSON format data instead of files.
      • Possible solutions:
        • Convert files to base64 format and send them to the backend in a string format.
          feng yang said it should be ok to use json file upload+request body. 
      • TODO: need feng yangto add a button + upload-file dialogue Xichen Panwill help this
  • node: Xichen Pan 
    • create (docker create), start (stopped-->running), stop (stop the container), delete (delete the node own info from DB), restart (docker restart); query (show node information from its uuid), download/update (config file: core.yaml for peer, orderer.yaml for orderer)
      • TODO: need feng yangto help add menu items to download/upload. Xichen Panwill fix this soon! 
      • https://github.com/hyperledger/cello/pull/492
    • Peer join channel. Upload a genesis block file of the channel (peer join channel with the genesis block of the channel: peer channel join -b ${APP_CHANNEL}.block) : 1pw
      • backend API is done: https://github.com/hyperledger/cello/pull/489
      • TODO: help add front-end menu
  • chaincode (wait till channel can add org): TODO: feng yang will draft a design spec first
    • package, install, approve, commit, invoke/query: 2pw
    • chaincode upload: org1 upload a zip file, and share it to org2 to upload.
    • org can approve/commit at its dashboard, and see other orgs' approval status.
• Yuanmao Zhu has contacted community for potential VM resource. sent email to community-architects@hyperledger.org.
  • Got replied, we need to create an issue for requesting VMs from CNCF, here is the link for that issue https://github.com/cncf/cluster/issues/221, feel free to leave comments.
• feng yang suggests the api-engine not check the token when the register/login API is called.  Will create an issue for Yuanmao Zhu
  • The solution is not putting token into register API's header.
  • Check whether the auth header is included when logout. feng yang
    • The answer is yes.
    • Xichen Panwill check if can disable the token checking at API-Engine backend for the register API.
      • register API does not check the token
