IBC-Relayer Ansible Setup

Design Philosophy

1. Support both hermes and rly
2. Make config file extensible by DRY principle

Guide

First copy it to your own inventory file so you can customize it to suit your needs:

cp inventory.sample inventory

rly installation

ansible-playbook main_rly_install.yml

Hermes installation

ansible-playbook main_hermes_install.yml

Hermes deployment

Here are two modes to deploy Hermes. For the Scaffolding Mode, you will specify a list of networks in the inventory file. For the Customization Mode, you will maintain your own jinja template.

For both, you will need to specify key_name, memo and a list of target ips in the inventory file. Examples are provided in the sample file.

ansible-playbook main_hermes_config.yml -e "target=mainnet"
ansible-playbook main_hermes_config.yml -e "target=testnet"

Scaffolding Mode

This mode is suitable if you just want to get the relay going quickly among a few networks.

You will fill in the list of networks you want to relay in the mainnet_networks or testnet_networks variables in the inventory file. The scaffolded config file will relay any channels among these networks.

Customization Mode

This mode is suitable when you connect lots of different networks and you want to fine-tune how they connect with each other.

You will leave mainnet_networks or testnet_networks blank in the inventory file. You will customize the mainnet.toml.j2 or testnet.toml.j2 files using our files as the starting point.
