I also am able to set up the AWS CLI to interact with minio or have the minio client interact with AWS S3.
While redundancy can be implemented with minio, I'll save that as a project for later.
I picked up a Raspberry Pi 4 8 GB model from Amazon ($150) and a 8 TB external USB drive from Costco ($120). One can always step down to a lower model / storage space if needed - just couldn't resist the savings on an 8 TB drive from Costco. :)
I downloaded the Raspbian Lite image, set up regionalization and my hostname. Attached the USB drive and created a brand new ext3 partition on the USB drive, wiping out everything else. Formatted and attached the drive and made sure it came up on reboots.
Then I downloaded minio using the wget process.
sudo ln -s /home/pi/minio /usr/bin/minio
sudo ln -s /home/pi/mc /usr/bin/mc
Then I made a simple shell script (start.sh) to launch minio.
/usr/bin/minio server /mnt/data
Then I made a file
Inside the file I put the following:
Description=Minio Storage Service
I then verified the service worked as intended:
$ sudo systemctl start minio
$ sudo systemctl status minio
Opened my browser, and once I logged in, I was able to access the minio service via browser and I made an alias for my minio client.
