Fedora CoreOS out of preview (Fedora Magazine) [LWN.net]

Fedora Magazine reports that the Fedora CoreOS distribution is now deemed ready for use. "Fedora CoreOS is a new Fedora Edition built specifically for running containerized workloads securely and at scale. It’s the successor to both Fedora Atomic Host and CoreOS Container Linux and is part of our effort to explore new ways of assembling and updating an OS. Fedora CoreOS combines the provisioning tools and automatic update model of Container Linux with the packaging technology, OCI support, and SELinux security of Atomic Host."

Flatcar Container Linux (https://www.flatcar-linux.org/) is a drop-in replacement for CoreOS Container Linux if, like us at Kinvolk, you were perfectly happy with how things worked.

It also supports an in-place update from CoreOS Container Linux.

This sounds nice. Maybe it's my fault that I have not heard about Kinvolk before. But running a production machine with a distro by a provider I have not even heard of sounds... frightening. Are you guys at FOSDEM in 2 weeks?

Does AWS provide statistics how often their AMIs have been used?

Well now you have. :)

We've been in business for about 5 years. We worked side-by-side with CoreOS to build the rkt container runtime. Through that work we got a very good understanding of CoreOS Container Linux and felt very comfortable picking it up. In fact, we announced that we were picking this up about 2 weeks after the CoreOSRH acquisition by Red Hat was announce, and published the first images shortly thereafter.

We've got paying subscription customers running several thousand nodes. It's simply that many folks don't want to make big changes for what is essentially an acquisition-driven (not technically-driven) change.

The whole IT business is sending the hot potato to someone else, or "I am not responsible, we have a contract support!"

I loved CoreOS as being an alternative, and Redhat reduced competition in this space.

Now, I have stopped my contributions to Openshift, for the following reasons:

1. Redhat uses Trademark to trump the freedom to make copies
2. IBM is the number one engine for restoring software patents in the US

I run a small CoreOS installation configured via terraform. EOS this year, but migration documentation not even available yet? I have the feeling something will break, even if my configuration is relatively small. Some details have deep dependencies into existing CoreOS configuration files.
