It works on my mac k8s instance, but not in my raspberry pi instance. Essentially im trying to set up a k8s cloud implementation of pihole. That way, I can monitor it, and keep it containerized as opposed to running outside the scope of the application. Ideally, im trying to containerize everything for cleanliness.

I am running on a 2 node Raspberry Pi 4, 4G /ea cluster.

When running the following file on my mac it builds correctly, but on the pi, named: master-pi, it will fail:

The YAML i implemented was pretty simple seemingly:

Other notes: I made sure I created the folders previously, and they are both chmod 777. df produces:

pi@master-pi:~/Documents/pihole$ df

So i believe the location has the size needed ( /home/pi/Documents/etc ) is just 1G but it looks half full, so ~15G available.

I can give more information, but I am just confused as to why this
