Add support for rkt (alternative container solution)
rkt is a another container implementation (like Docker) that is gaining popularity. See https://coreos.com/rkt/ https://coreos.com/rkt/docs/latest/rkt-vs-other-projects.html#rkt-vs-docker
"The Docker Engine is an application container runtime implemented as a central monolithic API daemon. Docker can resolve a “Docker Image” name, such as quay.io/coreos/etcd, and download, execute, and monitor the application container. Functionally, this is all similar to rkt; however, along with “Docker Images”, rkt can also download and run “App Container Images” (ACIs) specified by the App Container Specification (appc).
Besides also supporting ACIs, rkt has a substantially different architecture that is designed with composability and security in mind."
I believe rkt's approach is a better, more unix-like way of doing things, not requiring a daemon to run as root to operate.
When I saw the post on HN I searched for "rkt" and only found one comment about it, but I am sure there are others like me and the guy on HN that would like to see support for rkt on GitLab. https://news.ycombinator.com/item?id=11756744
What would be required to support rkt containers in the container registry?
