Developers of Linux distribution Fedora announced the release of Fedora CoreOS publicly available.
Fedora CoreOS is a completely new edition of Fedora distribution, replacing Fedora Atomic Host and CoreOS Container Linux products. The distribution developers urge users to migrate to Fedora CoreOS in a prompt manner, since the support for CoreOS Container Linux will be discontinued in the near future, and for Fedora Atomic Host it has already been discontinued.
We remind you that from version 21 Fedora distribution is released in three editions:
- Fedora Workstation — for personal computers.
- Fedora Server — for servers.
- Fedora Atomic — for cloud computing and containerizing.
The new edition offers secure containerized environment deployment at scale.
Since Fedora CoreOS is based on Fedora version 31, its components include Linux 5.4 kernel, Systemd 243 system manager, and Ignition 2.1 tools.
Podman 1.7 and Moby 18.09 ensure support for OCI and Docker Container.
cgroups v1 is enabled by default,
cgroups v2 should be activated via configuration.
The new Fedora CoreOS combines initialization tools and an automatic update model of CoreOS Container Linux, and package management technology, OSI (Open Container Initiative) support, and SELinux security of Fedora Atomic Host.
Fedora CoreOS can be installed on different platforms such as physical servers, QEMU, OpenStack and VMware, Alibaba, AWS, Azure, and GCP.
