People,

I have been following Fedora Atomic and CoreOS for a while and now I think I want to shift my server (as opposed to my workstation or laptop - I have been testing SilverBlue on the laptop) to CoreOS.  The server is basically used for the systems in the Subject - I will eventually move all the Jekyll and Rails apps (currently running as Docker containers) to other servers but I want to test out CoreOS on my own server first before setting up CoreOS VMs - QMail and EZMLM need to be built from C code and this has been streamlined for me for over a decade - but now I am thinking of creating a Podman container for Qmail and EZMLM.

Can people comment on any likely difficulties I might have?

I am in the process to upgrade my bare metal server from Atomic 29 to CoreOs in the coming weeks. I may share my potential issues and tricks if it can help. Until now, detailed documentation is hard to find.

Thanks for that - I might start experimenting anyway . .

Regards,

Phil.

One experiment:

I have an 8TB backup server installed with Atomic - am I able to do a bare-metal install by booting a live USB and then installing CoreOS BUT not touch the /home partition? - there should be plenty of space to install if the first four standard partitions are zapped?

The installer consumes a block device and overwrites the contents of it as if you were doing a `dd` of the provided disk image we give you. If you want to save the contents of your home partition I would suggest you copy the data off.

Of course there is a more complicated scenario where you've got your /home on a completely separate disk. In that case it might work, but I doubt you have it set up that way.

Right - I had assumed that was the case and recycled a SSD 140GB drive from an old NetBook and used that as the new sda and made the 6TB drive sdb - I had to manually use nmcli to change the IP address but otherwise things went pretty smoothly . .

Correct - copies of old HDs were just in /home (/dev/sda5).

Thanks!

Phil.

If you can build/run your application in a container then Fedora CoreOS should be a good candidate for that.

I have started the process . .

Thanks!
