CoreOS's Rocket launch aimed directly at Docker

Joab Jackson | Dec. 2, 2014
Citing concerns around Docker's security model and its increasingly complex supporting platform, CoreOS is developing Rocket, an alternative to the open-source container technology.

In contrast, Rocket runs as a simple command line program, containing only the commands to run an App Container Image (ACI). The ACI can be encrypted and distributed across multiple channels, such as BitTorrent, a public object storage service, or mirror networks. Rocket itself can be used not only on CoreOS but with any Linux distribution. CoreOS itself will continue to support Docker as well.

CoreOS posted a development version of the software, version 0.11, on GitHub. Due to Rocket still being in an early stage of development, Polvi did not estimate when a full production-ready version of the software would be available.

CoreOS is not the only Linux distributor working on an alternative to Docker. Last month, Canonical started work on a secure container-based technology, LXD (Linux Container Daemon) which it claims will offer the speed of Docker, but the security of a fully isolated virtual machine.
