• Fedora Atomic Host comes bundled with a version of Docker based on this project atomic repo that moves no faster than the upstream Kubernetes project can abide (currently docker-1.13.1).

  • While (pretty much) everyone who’s using docker is running it on Linux, and while lots of people run docker on their laptops and desktops, most aren’t running it directly on Linux desktops and laptops. Instead, most individual docker users are relying on some sort of purpose-built Linux distribution running as a virtual machine on their […]
