Docker has donated containerd, a core container runtime built by Docker with input from major cloud providers, to the Cloud Native Computing Foundation (CNCF). Containerd provides primitives for managing containers and works with projects like Docker Engine, Kubernetes, and CNCF projects. It has over 100 commits per month from many contributors and maintainers and is already widely used through Docker with millions of installs across industries.

10. containerd’s role in Container Ecosystem

11. containerd 1.0 planned for Q2 2017

12. containerd community
• 141 commits per month (avg)
• 17 unique contributors per month (avg)
• 7 new contributors in past 30 days
• 8 maintainers, from 5 companies

13. why CNCF?
Alignment with CNCF goals
• cloud native: container packaged, dynamically managed,
micro-services oriented
• containerd’s goal is to be a great core container runtime for cloud
native systems
Alignment with CNCF projects
• uses GRPC, exposes metrics in Prometheus format
• designed to be a great replacement for Docker as Kubernetes
CRI implementation
