Create .img file

Make the Pi-Node base .img.gz file for reuse

Put your micro sd card in your local machine and locate what it's called in /dev. For my laptop it is /dev/mmcblk0. Yours will likely be different.

sudo fdisk -l

After locating move into the directory you wish to save the image to and create the image.

>_ Terminal
# example
# sudo cat /dev/mmcblk0 > pi-node.img
sudo cat /dev/<your sd card> > pi-node.img

info

cat is better than dd for this. cat will use all of your systems cpu cores, whereas dd uses one core. cat is faster 🙀

Once that completes we will use PiShrink.sh to deflate partitions and compress (among a few other tricks).

>_ Terminal
wget https://raw.githubusercontent.com/Drewsif/PiShrink/master/pishrink.sh
chmod +x pishrink.sh
sudo mv pishrink.sh /usr/local/bin

>_ Terminal

sudo pishrink.sh -aZ pi-node.img Pi-Node.img.gz

pishrink.sh: Shrunk Pi-Node.img.gz from 7.5G to 1.3G ...

And there you have it! 🧙♂
