Thanks skj.. any plans of supporting containers other than docker ?
Briefly, you can run any container image as a build step with this service, including one that builds rocket containers, and including one that pushes them. But, we're not currently offering any direct support for this ability.
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.
