Fabric development environment on a single server

This Ansible playbook was written to create simple Hyperledger Fabric networks for the purpose of testing. It installs fabric-dev-servers and its requirements on a single machine. Until now this was tested with Amazon Linux 2 AMI and Ubuntu 18.04.1 LTS (using Vagrant).

Usage

Prerequisite

Make sure you have Ansible and composer-cli installed.

If you just want to test this setup, feel free to use Vagrant. This repository comes with a suitable Vagrantfile, start the machine using vagrant up. Once started, run vagrant ssh to connect to the machine initially. Then append the machines ssh-config to ~/.ssh/config if you like:

vagrant ssh-config >> ~/.ssh/config

You should now be able to run ssh ubuntu-vagrant. ubuntu-vagrant now is the host you can use in the hosts-file (skip the sections of this tutorial until you get to "Setup and configuration"). The public IP, available from your host machine, will be 192.168.50.4.

Server and SSH access

First, create yourself a virtual server somewhere (e.g. AWS EC2). Ensure to have key based SSH access to it, for example by configuration in ~/.ssh/config:

Host my-host
    Hostname my-host-ip-or-name
    User ec2-user
    IdentityFile ~/.ssh/keypairs/my-keypair.pem

Inbound traffic

Make sure to allow inbound traffic to the server (e.g. via a AWS Security Group) to the following ports:

  • 8080 – Composer Playground
  • 7054 – ca.org1
  • 7051 and 7053 – peer0.org1
  • 7050 – Orderer
  • SSH port of your choice
  • Maybe additional ones for different composer-rest-server instances

Setup and configuration

  1. Clone this repository: git clone git@github.com:jverhoelen/hyperledger-fabric-dev-ansible.git && cd hyperledger-fabric-dev-ansible
  2. (Optional) adjust variables.yml for configuration. The default variables should already be stable.
  3. Create your hosts file and insert the host you have access to, e.g. my-host from the SSH config

Provision the server

Let's go:

ansible-playbook -i ./hosts playbook.yml

Note: On the first run(s) there can be an issue with task Download fabric docker images by script. It may complain about your user not having sufficient rights for Docker although the user has been added to the docker group before. Just run it again. If is takes too long, you can also consider to login manually and execute ~/fabric-tools/downloadFabric.sh.
