rpupdate

My setup:

• Hybrid setup running in dockerized containers.
• Docker network created with: docker network create --gateway 192.168.32.1 --subnet 192.168.32.0/24 net
• Hybrid eth1 and eth2 containers are named eth1 and eth2, with the same port config as Rocket Pool default settings.
• All containers connect to the external net network.
• I changed the user ID on certain containers because I prefer to not use docker volumes, and this way I can include them with my backups when running this script.
