Minecraft on Raspberry Pi cluster with metrics

Ever wanted to put your Rapsberry Pi cluster to great use? Our team is working remotely, so we started to play Minecraft. I decided I would host the Minecraft server on my Raspberry Pi cluster. This gist will guide you through the steps I took to get a k3s cluster up with k3sup and later installed Minecraft as well as metrics exporter and Prometheus Operator

Why?

Quoniam Possumus - Because we can

You'll need

ancap

#Nginx debug# Use strace. First, you need to detect PID of nginx process:

# ps ax | grep nginx
25043 ?        Ss     0:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
25044 ?        S      0:02 nginx: worker process

Ok, so 25044 is the worker process. Now, we trace it:

# strace -p 25044 2>&1 | grep gz
