containerd vs rkt: What are the differences?

Developers describe containerd as "An industry-standard container runtime with an emphasis on simplicity,robustness and portability". An industry-standard container runtime with an emphasis on simplicity, robustness, and portability. On the other hand, rkt is detailed as "App Container runtime". Rocket is a cli for running App Containers. The goal of rocket is to be composable, secure, and fast.

containerd and rkt are primarily classified as "Container" and "Virtual Machine Platforms & Containers" tools respectively.

Some of the features offered by containerd are:

  • OCI Image Spec support
  • OCI Runtime Spec support (aka runC)
  • Image push and pull support

On the other hand, rkt provides the following key features:

  • Composable. All tools for downloading, installing, and running containers should be well integrated, but independent and composable.
  • Security. Isolation should be pluggable, and the crypto primitives for strong trust, image auditing and application identity should exist from day one.
  • Image distribution. Discovery of container images should be simple and facilitate a federated namespace, and distributed retrieval. This opens the possibility of alternative protocols, such as BitTorrent, and deployments to private environments without the requirement of a registry.

rkt is an open source tool with 8.71K GitHub stars and 832 GitHub forks. Here's a link to rkt's open source repository on GitHub.
