# Ansible playbooks for deploying cross-chain bridges
|
|
|
|
## Bridge Overview
|
|
|
|
The POA Bridge allows users to transfer assets between two chains in the Ethereum ecosystem. It is composed of several elements which are located in different POA Network repositories:
|
|
|
|
**Bridge Elements**
|
|
1. Deployment Playbooks. Configuration management instructions for validator nodes contained in this repository.
|
|
2. [Bridge Smart Contracts](https://github.com/poanetwork/poa-bridge-contracts). Solidity contracts used to manage bridge validators, collect signatures, and confirm asset relay and disposal.
|
|
3. [Token Bridge](https://github.com/poanetwork/token-bridge). The token bridge oracle written in NodeJS.
|
|
4. [Bridge UI Application](https://github.com/poanetwork/bridge-ui). A DApp interface to transfer tokens and coins between chains.
|
|
5. [Bridge Monitor](https://github.com/poanetwork/bridge-monitor). A tool for checking balances and unprocessed events in bridged networks.
|
|
|
|
|
|
## Playbooks Overview
|
|
|
|
These playbooks are designed to automate the deployment process for cross-chain bridges on bridge validator nodes. This process installs the bridge as a service and sets .env configurations on a remote server. Playbooks for the current token-bridge deployment are located in the [bridge-nodejs](bridge-nodejs) folder.
|
|
|
|
|
|
### Rust Bridge Playbooks
|
|
|
|
The Rust bridge is not currently in production, but an Ansible playbook is developed for this implementation. It is available in the [upgradable-wo-parity](upgradable-wo-parity)folder.
|
|
|
|
## Dependencies
|
|
|
|
The playbooks automatically install `Docker`, `docker-compose`, `Python`, `Git`and it dependencies (such as `curl`, `ca-certificates`, `apt-transport-https`, etc.). Install [Ansible](https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html) to launch playbooks.
|
|
|
|
## Configuration
|
|
|
|
Please see the [bridge-nodejs README](bridge-nodejs/README.md) for configuration and execution details.
|
|
|
|
## Bridge service commands
|
|
|
|
The Bridge service is named `poabridge`. Use the default `SysVinit` commands to `start`, `stop`, `restart`, and `rebuild` the service and to check the `status` of the service.
|
|
|
|
Commands format:
|
|
```bash
|
|
sudo service poabridge [start|stop|restart|status|rebuild]
|
|
```
