The Cloud Native Computing Foundation (CNCF) appears to be suffering an embarrassment of container technology riches. Docker Inc., after pledging to give up control of the lower level run-time Docker functions as promised, is proposing the CNCF will now be responsible for continuing the development of containerd as an open-source project. At the same time, CoreOS announced that it, too, is proposing the CNCF take control over the rival rkt container platform.
