FogLedger is a plugin for Fogbed. It is a framework and toolset integration for the rapid prototyping of fog components in virtualized environments using a desktop approach for DLTs. Its design meets the postulated requirements of low cost, flexible setup, and compatibility with real-world technologies. The components are based on a Mininet network emulator with Docker container instances as fog virtual nodes.
Before installing Fogbed it is necessary to install some dependencies and Containernet, as shown in the steps below:
sudo apt-get install ansible
git clone https://github.com/containernet/containernet.git
sudo ansible-playbook -i "localhost," -c local containernet/ansible/install.yml
sudo pip install -U git+https://github.com/EsauM10/fogbed.git
sudo pip install -U git+https://github.com/larsid/FogLedger.git
cd examples/indy
cd examples/iota
sudo python3 test-local-network.py
sudo python3 test-distributed-network.py
from typing import List
from fogbed import (setLogLevel, FogbedDistributedExperiment)
import time
import os
from fogledger-indy import (IndyBasic, Node)
setLogLevel('info')
if (__name__ == '__main__'):
exp = FogbedDistributedExperiment()
worker1 = exp.add_worker('YOUR_HOST_IP or HOST_NAME')
# Define Indy network in cloud
indyCloud = IndyBasic(
exp=exp, trustees_path='examples/tmp/trustees.csv', config_nodes=[
Node(name='ledger1'),
Node(name='ledger2'),
Node(name='ledger3'),
Node(name='ledger4'),
])
for ledger in indyCloud.ledgers:
worker1.add(ledger)
worker1.add_link(edge1, ledger)
try:
exp.start()
indyCloud.start_network()
input('Press any key...')
except Exception as ex:
print(ex)
finally:
exp.stop()
