Docker Comes Under Rocket Fire from CoreOS
Page 1 of 1
Rocket is completely new and isn't a fork of Docker, Alex Polvi, CEO of CoreOS, told eWEEK. CoreOS is an open-source operating system vendor that uses Docker containers as a basic building block to deploy clustered applications. The first stable CoreOS release debuted on July 25.
CoreOS started the Rocket effort because of a number of perceived deficiencies in Docker.
"We went about this because Docker is no longer a standard composable unit; Docker is a platform which now includes clustering, cloud server provisioning and more," Polvi said. "The community needs a simple composable unit that can be used in a variety systems—this is why we introduced Rocket and the App Container specification."
