Containerdcontainerd 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 [[Open Container Initiative|OCI]] Specification to The Linux Foundation with a reference implementation called runc. Since February 28, 2019 it is an official CNCF project.<ref>{{Cite web | url=https://www.cncf.io/announcement/2019/02/28/cncf-announces-containerd-graduation/ | title=Cloud Native Computing Foundation Announces containerd Graduation| date=28 February 2019}}</ref> Its general availability and intention to donate the project to CNCF was announced by Docker in 2017.<ref>{{Cite web |url=https://www.docker.com/blog/cncf-containerd-1-0-ga-announcement/ |title=Announcing the General Availability of containerd 1.0, the industry-standard runtime used by millions of users |date=2017-12-05 |website=Docker Blog |language=en-US |access-date=2020-01-20}}</ref><ref>{{Cite web |url=https://www.docker.com/blog/docker-donates-containerd-to-cncf/ |title=Docker to donate containerd to the Cloud Native Computing Foundation |date=2017-03-15 |website=Docker Blog |language=en-US |access-date=2020-01-20}}</ref>
