Substrate Private Network Ansible Repo

This Repo contains different ansible roles for different Purpose

You can learn about substrate private network setup at https://substrate.dev/docs/en/tutorials/start-a-private-network-with-substrate

Ansible Roles

• substrate-role: This Role is used to deploy a private substrate or polkadot network of two nodes with a custom genesis file.
• explorer-ui: This Role is used to deploy the polkadot Explorer UI.
• monitoring:This Role is used to setup and configure the ELK System.
• metrics: This role is used to configure & push the monitoring metrics such as system, nginx, etc on the ELK system.

Prerequitics:

• The Roles are tested on ubuntu 16.04
• Ansible version is 2.8.6

Instructions to setup the whole system:

Setup Ansible Server:

• Launch an ec2 server in aws
• Install Ansible
• Modify the hosts file and create multiple hosts as per your requirement.

Sample host file:

[explorer-ui]
54.162.7.156
[monitoring]
54.84.164.236
[substrate-node]
54.224.47.244
3.90.115.34 

Change the ansible.cfg according to the requirement.
   A. host_key_checking = False
   B. remote_user = ubuntu
   C. private_key_file = /home/ubuntu/demo.pem

Setup the Substrate Nodes:

1. Launch 2 aws ec2 Instances ( Please use atleast t2.medium )
2. Add the public IPs of both the instances in the host file.
3. Add both these also in the substrate-node.yml file to make one node as validator node ( where the custom genesis file is generated ) and other node called as additional node.

Sample substrate-node.yml file:

---
- hosts: substrate-node
  vars:
    consensus_authorities: []
    validator_node_id: ""
    validator_node: 54.224.47.244
    additional_node: 3.90.115.34
  roles:
    - substrate-node

• After this, Please run the playbook: ansible-playbook substrate-node.yml
• This is configure both the nodes and create the network. You can check by log in to the instances.

Setup the Explorer UI server:

• Launch an aws EC2 instance ( atleast t2.medium )
• Add the public IP of the instance in the host file.
• Run the ansible playbook:ansible-playbook explorer-ui.yml
• It will Setup the explorer-ui and setup nginx also. You can open on http://PUBLIC_IP_OF_INSTANCE.

Setup the ELK server:

• Launch an aws EC2 instance ( atleast t2.medium )
• Add the public IP of the instance in the host file.
• Run the ansible playbook: ansible-playbook monitoring.yml
• It will Setup the elasticsearch, kibana, nginx. You can open the kibana dashboard on http://PUBLIC_IP_OF_INSTANCE.

Setup and configure the Metrics to push on ELK Server:

• You can use this role with any other playbooks like with explorer-ui , substrate-node etc. This role is used to setup the metricbeat and heartbeat on the required servers.
• You need to change the default variable values like elasticsearch and kibana URL so that beats can push the metrics on the ELK or monitoring Server.
• For adding defined metrics, Please change the default files for the services
