Init docker swarm and overlay network, once

docker swarm init --task-history-limit 1
docker network create --driver=overlay --attachable --opt encrypted electrsnet

Do the following line only if data doesn't already exist / isn't already mounted

sudo mkfs.ext4 /dev/vdc
cd ; mkdir data ; sudo mount /dev/vdc data/

Build the image -- if updating, remove all cached images

./build.sh
