Place both files in the same folder and execute this:

# required for elasticsearch
sudo sysctl -w vm.max_map_count=262144
# create folders
mkdir ./data ./logs
# own these in order to have them writable
sudo chown 500:500 -R ./data ./logs
# start via docker-compose
docker-compose up -d

Works on my personal Raspberry Pi 4 with 8GB RAM including a lot of other tools, so plenty room for more.
