CoreOS Takes a Swipe at Docker

This Docker vs. Rocket thing feels like a full-blown go in the Octagon

CoreOS Takes a Swipe at Docker
By JDH

If watching your in-laws awkwardly bicker on Thanksgiving weekend wasn't enough for you, this Docker vs. Rocket thing feels like a full-blown go in the Octagon.

For context, CoreOS announced on Monday that they don't agree with the direction Docker is headed, and are creating their own container runtime called Rocket. They cite less-than-stellar security, speed, and overcomplexity as reasons to compete with Docker, and decided to take the matter into their own hands. The kickoff blog post, which uses a good bit of stern language (in the context of a product introduction anyway), says Docker's security model is "broken" and other bits are "fundamentally flawed."



CoreOS intends to differentiate Rocket by keeping their container model simple and allowing users to avoid the "baggage" of Docker, while providing some novel security enhancements such as giving a unique identity to each instance of a running container and an HSM-like service for signing.

This was met with a comment on Hacker News by Solomon Hykes of Docker, saying he's more than disappointed by CoreOS' mudslinging. He goes on to defend Docker's decision-making, and outlines 13 principles.

ScriptRock makes GuardRail, a DevOps-ready platform for configuration monitoring.

Then we took the concept a step further, giving it a beautiful interface and making it simple enough for our bosses to understand. We named it GuardRail after its function — to allow businesses to move fast and stay safe.

GuardRail scans and tracks much more than just servers in a datacenter. It works with network hardware, Cloud service providers, CloudFlare, Android devices, infrastructure, and more.
