WORK IN PROGRESS - THIS IS NOT INTENDED FOR PRODUCTION

This example assumes reth and lighthouse are both on localhost.

• Reth --datadir path: /mnt/reth/datadir

Start by installing reth:

 sudo snap install reth

(Optionally) Set the snap to not restart after an automatic upgrade. You need to restart the reth-daemon yourself if set.

 sudo snap set reth endure=true

Install and use with "lighthouse" to participate in the ethereum network.

 sudo snap install lighthouse

Check and change the configuration of reth and/or lighthouse to your liking:

 snap get lighthouse
 snap get reth

Change the location of the --datadir and allow the snap to access some external filsystems/dirs (see: snap interface removable-media)

 sudo snap connect reth:removable-media
 sudo snap set reth service-args='node --full --datadir /mnt/reth/datadir'

Start reth.

 sudo snap start reth

Copy the jwt.hex from where you set the reth --datadir -> lighthouse

 sudo cp /mnt/reth/datadir/jwt.hex /var/snap/lighthouse/common/

Start lighthouse:

 sudo snap start lighthouse

Check logs:

 sudo snap logs reth -f
 sudo snap logs lighthouse -f

Optionally, check the file-log in the snap location:

 sudo tail -f /root/snap/reth/current/.cache/reth/logs/mainnet/reth.log
