rkt supports running Docker Images[1], Open Container Initiative (OCI) Images[2], and appc images. So, any container image this system builds will run under rkt. rkt is explicitly designed as a container engine not as a container build system. And this is because build and execute are largely separate concerns. And it leaves the door open for new build systems as demonstrated here by Google.
