Atomic Host.

Share this link

If you like containers, at some point you will deploy them into production. And you will need a dedicated server to host them.
Atomic Host is the RedHat solution for this.
It is a lightweight version of RHEL/CentOS 7 (there is also a Fedora version) where :

  • only the /etc and /var directories are writable,
  • all the OS can be upgraded or rolled back atomically (hence the name) through the rpm-ostree mechanism,
  • there is no yum command nor man pages.

Take the time to discover this new animal through the Atomic Host tutorial.
