Tool for easy Hyperledger Fabric network reconfiguration by committing a new configuration transaction

Reference

• Connect new organization

• Connect new RAFT orderer

Connect new organization

1. Build Fabchanger:

   go build -o fabchanger cmd/main.go
   

2. Generate new crypto materials

   Edit config/config.yaml

   Generate configs:

    ./fabchanger --mode generate --join org
   

3. Create connection profile and refer to it from config/config.yaml.

4. Run command:

   ./connectOrg.sh
   

5. Sign configuration transaction

   Sign as admin specified in config/config.yaml:

   ./fabchanger --mode sign -f ./wrappedDelta.pb -o ./wrappedDelta.pb 
   

   Repeat this step for all orgs (change credentials in config/config.yaml and run command specified above)

   Commit tx to orderer:

   ./fabchanger --mode update -f ./wrappedDelta.pb
