rkt - the pod-native container engine
rkt (pronounced like a "rocket") is a CLI for running application containers on Linux. rkt is designed to be secure, composable, and standards-based.
Some of rkt's key features and goals include:
Project status
The rkt v1.x series provides command line user interface and on-disk data structures stability for external development. Any major changes to those primary areas will be clearly communicated, and a formal deprecation process conducted for any retired features.
Check out the roadmap for more details on the future of rkt.
Trying out rkt
To get started quickly using rkt for the first time, start with the "trying out rkt" document.
Also check rkt support on your Linux distribution.
For an end-to-end example of building an application from scratch and running it with rkt, check out the getting started guide.
Getting help with rkt
There are a number of different avenues for seeking help and communicating with the rkt community:
- For bugs and feature requests (including documentation!), file an issue
- For general discussion about both using and developing rkt, join the rkt-dev mailing list
- For real-time discussion, join us on IRC: #rkt-dev on freenode.org
- For more details on rkt development plans, check out the GitHub milestones
Most discussion about rkt development happens on GitHub via issues and pull requests.
The rkt developers also host a semi-regular community sync meeting open to the public.
This sync usually features demos, updates on the roadmap, and time for anyone from the community to ask questions of the developers or share users stories with others.
For more details, including how to join and recordings of previous syncs, see the sync doc on Google Docs.
