Containerd is an industry-standard core container runtime. It is currently available as a daemon for Linux and Windows, which can manage the complete container lifecycle of its host system. In 2015, Docker donated the OCI Specification to The Linux Foundation with a reference implementation called runc. Since 28 February 2019, it is an official CNCF project. Its general availability and intention to donate the project to CNCF was announced by Docker in 2017.
Troubleshooting containers
For debugging or troubleshooting on Linux nodes, you can interact with containerd using the portable command-line tool built for Kubernetes container runtimes: crictl. crictl supports common functionalities to view containers and images, read logs, and execute commands in the containers. Refer to the crictl user guide for the complete set of supported features and usage information.
View container logs with systemd:
$ journalctl -u containerd
