Quick Dirty Redis Nspawn Container on Arch Linux
Refer to the Nspawn page for setting up the nspawn container, install redis, and start/enable redis.service. Once you have the container running, it seems all you have to do to get things working in a container subnet is to change the bind address.
# /etc/redis.conf # bind 127.0.0.1 bind 0.0.0.0
you can nmap port 6379, be sure to restart redis
