Running a DCLedger Node using Ansible (Prerequisites)

Requirements (local machine)

1. Clone DCL project

git clone https://github.com/zigbee-alliance/distributed-compliance-ledger.git

2. Install Python and Pip

sudo apt-get update
sudo apt-get install -y --no-install-recommends python3
sudo apt install python3-pip python3-testresources

3. Install Ansible and its dependencies

Run the following commands from the DCL project home

sudo pip install -r deployment/requirements.txt
ansible-galaxy install -r deployment/galaxy-requirements.yml

Requirements (target machine)

Hardware requirements

Minimal:

  • 1GB RAM
  • 25GB of disk space
  • 1.4 GHz CPU

Recommended (for highload applications):

  • 2GB RAM
  • 100GB SSD
  • x64 2.0 GHz 2v CPU

Operating System

Current delivery is compiled and tested under Ubuntu 20.04 LTS so we recommend using this distribution for now. In future, it will be possible to compile the application for a wide range of operating systems (thanks to Go language).

Install Python

Python3 needs to be installed on target machine to run ansible playbooks

sudo apt-get update
sudo apt-get install -y --no-install-recommends python3
