I have one Raspberry Pi (3 Model B) with mostly working software. I will need 6 Pi's (same model) to behave similarly.
So I thought that it would be a grat idea to just clone 6 SD cards from working one and hope that all 6 Pi's will work fine.
However I expect that something can go wrong.
I know that use of Docker or something should be a better solution. But I don't have any experience with Docker and don't have any sufficient time to make this possible.
1) So is cloning if SD card a good solution?
2) If not - what can be a better solution?
So, today I made it: I've cloned 5 8Gb cards from 1 master with Win32 Disk Imager software.
All Pi's worked fine for me. I wasn't able to check if everything was OK. But it looks completely fine. Each SD card took about 7 minutes to write the image, which is not very long but for production can be a pain.
UPDATE 2: important!
Today I made another 8 SD's for same Raspberri pi 3 model b. I didn't expect any problems. However, all 8 pi's didn't even flashes with LAN led's ☹️
I had to flash fresh Buster OS and repeat all setup. After that everything was fine.
So important peace of experience: cloning SD's can give a bad result
