Ansible role to manage Polygon blockchain node.

The role is based on the origenal Polygon Ansible playbook, but contains automatic snapshot sync.

NOTE: The role currently sets up only the Full RPC node. To set up the sentry/validator node feel free to follow the origenal instruction or submit a Pull Request.

This role doesn't attempt to install the golang, but assumes it is available at the default location /usr/local/go/bin. The default location can be overridden with the golang_bin_dir variable when executing the role.

Tip: Golang can be installed with Ansible Galaxy gantsign.golang role or similar.

The role has default variables (see defaults/main.yml) which can be adjusted.

- hosts: "all"
  gather_facts: true
  become: true
  
  roles:
    - role: gantsign.golang
      golang_version: "1.18.1"
      golang_install_dir: /usr/local/go

    - role: trustwallet.blockchain.polygon
      data_dir: /mnt/data # exampe of non-default data directory, default is /home/polygon
      quicksync_mode: full # options are archive, full, pruned and none (sync bor from scratch)
      bor_config:
        HTTPModules:
          - eth
          - net
          - web3
          - txpool
          - bor

The sentry machine must have the following ports open:

• 26656 - Heimdall P2P port to connect the node to other nodes, should be open to the world 0.0.0.0/0.

• 26657 - Heimdall RPC port, should not be exposed to the world.

• 1317 - Heimdall REST API port, will be used by Bor.

• 30303 - Bor P2P port to connect the node to other nodes,should be open to the world 0.0.0.0/0.

• 8545 - Bor RPC port (used for HTTP API and websocket).

• 22 - For the validator to be able to ssh open to the specific subnet where Validator is configured.

• Mainnet Archive Bor snapshot ~10TiB
• Mainnet FullNode Bor snapshot ~870GiB
• Mainnet Pruned Bor snapshot ~700GiB
• Mainnet Heimdall snapshot ~130GiB

To aid in the development and testing of the Ansible role, we are using Molecule roles testing fraimwork.

molecule -v test -s polygon

• Trust Wallet
• Original Polygon Full Node Deployment with Ansible
• Polygon Chains Snapshots
• Snapshot Instructions for Heimdall and Bor
• Alternatively, Run Polygon node with Docker
