Ansible playbook for Berachain Validators and RPCs delivered to bare metal servers. This playbook is intended for node runners who utilize bare metal servers, delivering both Beacond and Reth, Geth or Nethermind via Docker.
- Ability to initialize an Berachain node (validator, rpc) via docker containers, including initing the node, configuring beacond, and running container with proper port management.
- Ability to run reth, geth or nethermind as an execution layer engine. Set
execution_clientin the appropriate vars file as well as included the appropriate execution version. - Ability to upgrade to a new versions when requested for planned upgrades.
- This playbook does not include core server setup, security, monitoring, or power management components necessary for server security and performance. These components are the responsibility of the operator.
- Assumes docker is installed and all appropriate firewall rules are in place (docker ports will bypass ufw)
- Utilizes Berachain team provided beacond config files & modifies only necessary components. Therefore if additional chain configurations or tweaks are utilized, re-running these playbooks will add/modify those configurations.
- This repo is entirely impotent and can be re-run indefinitely.
