rkt

What do you like best?

Rocket (rkt) is a container runtime engine, unlike Docker (the main container technology today), it is build from the ground up with security in mind. Its is also integrated with linux security standards like SELinux. For instance, it allows you to sign images and check the integrity of images before running them. It also build around the unix binary standard and thus it can easily integrated with init systems (e.g. systemd).

What do you dislike?

It still lack a lot of features that make it easily start using it. For instance, unlike docker it doesn't have a GUI and runs only on Unix-like systems (no runtime for Windows or OS X). It's stil a young project that's not very mature and it lacks integrations with tools in the container ecosystem (e.g. kubernetes).

Recommendations to others considering the product:

Rocket is a project to watch closely, it is in ints early stage but seems promising as the company (i.e. CoreOS) behind is putting a lot of efforts.

What problems are you solving with the product? What benefits have you realized?

I looked for rkt when I was looking for a containerasation solution, I find it a good solution but as it was not very mature (especially it's integration with other toolings) I've end up not choosing it.
