This document outlines a 5-step process to deploy Hyperledger Fabric on multiple nodes. Step 1 involves cloning a GitHub repository containing a Fabric starter kit. Step 2 configures the network by mapping domain names to IP addresses for the orderer and 3 peer organizations. Step 3 generates certificates for each organization. Step 4 generates the orderer genesis block and starts the orderer. Step 5 connects each organization's peers to the channel. Finally, the document describes launching the Fabric API and experimenting with the private blockchain network.

3. Step 0. Prerequisites
Preparatory stage:
Run (if any update needed):
$ sudo apt-get update && sudo apt-get -y install docker-compose git jq
$ sudo usermod -aG docker $USER
$ exit
Environment:
Four working stations or cloud instances with:
▪ Linux Ubuntu 16.04 (or, Cent OS 7)
▪ Docker-CE (v. 17.12.1-ce) and Docker-Compose (v. 1.8.0)

4. Step 1. Get Fabric-Starter form GitHub
Clone the following Altoros’s repository:
$ git clone https://github.com/Altoros/fabric-starter.git
$ cd fabric-starter
On all 4 nodes!

5. Step 2. Network configuration: mapping Nodes
Map domain names to real IPs:
$ export IP_ORDERER=18.222.125.243
IP1=18.191.152.58 IP2=18.222.145.192
IP3=18.191.209.53On all 4 nodes!

6. Step 3. Each member generates Certificates
Organization A on its host:
$ ./network.sh -m generate-peer –o a
Organization B on its host:
$ ./network.sh -m generate-peer –o b
Organization C on its host:
$ ./network.sh -m generate-peer –o c
You can examine what has been
generated on your host:
$ ls -lha

7. Step 4. Generating the Orderer
The Orderer generates a genesis block:
$ ./network.sh -m generate-orderer
Start the Orderer:
$ ./network.sh -m up-orderer

8. Step 5. Orgs connect their Peers
Organization A on its host:
$ ./network.sh -m up-1
Organization B on its host:
$ ./network.sh -m up-2
Organization C on its host:
$ ./network.sh -m up-3

9. Launch the Fabric API
1. Copy the Organization’s IP to the web browser address bar
2. Open the port: 4000
3. Go to admin section

10. Experiment with your private blockchain
