Dependencies

• virtual machine environment
• docker
• fabric binaries

Installation

• Download the vagrant environment https://drive.google.com/file/d/1VEA_GMVkFieWBnGa8zVvSfcCO5VVnngc/view?usp=sharing and extract the file to obtain the vagrant machine directory.
• Navigate to the directory and run vagrant up.
• After the VM is up, run vagrant ssh, this will connect your terminal to the Ubuntu VM via CLI that we will be using for interacting with our environment. (Keep atleast 4 terminals open).
• The necessary identities that are required to put up a network are already created, only use the CA client to add new users to the network.
• Run the clean.sh scripts in the orderer and peer directory and clean-peer-ledger-folder.sh in the peer directory.

Running the CA Server

• The CA server must be running in order to register and enroll new identities to the network.

$ export FABRIC_CA_SERVER_HOME=/vagrant/demoforlab/ca/multi-org-ca/server
$ fabric-ca-server start

Running the orderer node

• The CA server must be running in order to register and enroll new identities to the network.

$ cd demoforlab/orderer/multi-org-ca/
$ ./generate-genesis.sh
$ ./generate-channel-tx.sh
# ./launch.sh

Running the peer node

• Following commands show how to run a peer node and join the healthcare channel.

$ cd demoforlab/peer/multi-org-ca/
$ . set-env.sh healthcare peer1 7050 admin
$ ./sign-channel-tx.sh
$ ./submit-create-channel.sh
$ ./launch.sh healthcare peer1 7050 

• Now switch to another terminal connected to the vagrant machine.

$ . set-env.sh healthcare peer1 7050 admin
$ ./join-healthcare-channel.sh

Registering a new user

• The CA server must be running in order to register and enroll new identities to the network.
• Only the healthcare-admin is capable of adding users with the custom attributes that shows association with a user.

$ cd demoforlab/ca/multi-org-ca/
$ . setclient.sh healthcare admin

• Available affiliations : "healthcare.patient", "healthcare.staff", "healthcare.others", "research", "thirdparty".

$ fabric-ca-client register --id.name <enrollment-ID> --id.type user --id.affiliation <appropriate affiliation> --id.secret <enrollment-secret> --id.attrs <dataOwner#>=<#level>:ecert
$ . setclient <org-name> <enrollment-ID>

$ fabric-ca-client enroll -u http://<enrollment-ID>:<enrollment-secret>

• Example

$ fabric-ca-client enroll -u http://dataOwner1:pw@localhost:7054

• Here "dataOwner1" is the enrollment-id and "pw" is the enrollment secret.
