A docker-compose file to quickly spin up an Ethereum PoS node

Configuration

Before starting the container, there are a few things to configure in docker-compose.yml, errors WILL be thrown if you do not edit these.

• On lines 17 and 55 under volumes, replace <PATH-ON-HOST> with either a docker volume, or a path to mount the volume to on the host.
  
  • For Example: ${HOME}/eth-data would mount the data directory to home in a dir named eth-data
• On line 66 in the flag --p2p-host-ip replace <HOST-IP-HERE> with the host machines IP.
  
  • This can be found quickly with the following command: curl ifconfig.io
  • This flag is not a hard requirement, so can be removed if necessary. But it is reccomended to be a good peer to the network
• On line 64, in the flag suggested-fee-recipiant, put your ETH wallet address in

Run

To run the container, simply run the command docker-compose up -d from within the same directory your docker-compose.yml is in

Firewall & Port Forwarding

In order to have a secured, but reachable node, it is important to make the following changes in both your hosts firewall, and your networks router. A more complete list of firewall security best practices check out Prysm's port and firewall page

• Firewall
  • Port 8445: DENY
  • Port 3500: DENY
  • Port 8551: DENY
  • Port 4000: DENY
  • Port 12000: ALLOW
  • Port 13000: ALLOW
  • Port 30303: Allow
• Port Forwarding
  • Open Port 12000 UDP
  • Open Port 13000 TCP
