I'm running a few bare metal Fedora CoreOS nodes and its been a dream with IPMI, ignition files, containers, and ansible to orchestrate it all.
Havent used Flatcar Linux but I have seen the experience is similar.
CoreOS has indeed since been deprecated, however when Redhat acquired CoreOS in Jan 2018 they merged CoreOS and Project Atomic to create Redhat CoreOS. They also released Fedora CoreOS which shares some technologies with vanilla Fedora and Silverblue.
Shortly after the acquisition, Flatcar Container Linux was released which is an updated derivative of the original CoreOS.
Wow, thank you for this, I had no idea. What a mess made by this acquisition, reusing the name of a deprecated product isn't really a great idea. Though I'm glad to know there are ways to go back to a CoreOS-like experience, that has been my favorite server setup for a while.
Agreed, the original CoreOS is by far my favorite server OS so far. I was very sad to see it get sold to RedHat, though few other people shared my concern at the time[0]. I wish I could say my concern turned out to be unjustified, but alas here we are.
I do recommend Flatcar linux though, and strongly encourage everyone to check it out. Not as jazzed about the name, but what’s in a name?
