nerdctl is yet a new player in container engine scene. It leverages the containerd much more than Docker and offers 2 new features:
* lazy pulling
* image encryption
Though it is quite young, the project is growing steadily. In
https://github.com/containerd/nerdctl/pull/139, the team maintainer adds support for ppc64le.
To me it is a yet another win for Linux ppc64le community
