Docker published two blog posts behind the rational for createion of “ runc” and “ containerd”.containerd has full support for starting OCI bundles and managing their lifecycle.Docker also created the “containerd” project for the supervision of the containers spawns out using “runc”.The low level container runtime features were moved to a different project called runc, it was the first OCI runtime spec reference implementation.Some of the runtimes like “rkt” does most of the tasks by itself, where as runtime like “containerd” does some of the high level functions and uses others like “runc” for some of the low level tasks. So in a nutshell the container runtimes does some or all of the below tasks: rkt : rkt is an application container engine developed by.It is a lightweight alternative to using Docker as the runtime for Kubernetes. cri-o : CRI-O is an implementation of the Kubernetes CRI (Container Runtime Interface) to enable using OCI (Open Container Initiative) compatible runtimes.

It was developed by Docker Inc and donated to OCI as the first OCI runtime-spec compliant reference implementation.

runc : runc is a CLI tool for spawning and running containers according to the OCI specification.lxc: LXC provides OS level virtualization through a virtual environment that has its own process and network space, it uses linux cgroups and namespaces to provide the isolation.containerd: A CNCF project, it manages the complete container lifecycle of its host system that includes image management, storage and container lifecycle, supervision, execution and networking.Some of the the popular container runtimes are below ones:

OCI image spec defines how to create an OCI Image, which includes an image manifest, a filesystem (layer) serialization, and an image configuration.

OCI runtime spec defines how to run the OCI image bundle as a container.

OCI currently contains two specifications: the Runtime Specification ( runtime-spec) and the Image Specification ( image-spec).

Established in June 2015 by Docker and other leaders in the container industry.

The Open Container Initiative ( OCI) is a Linux Foundation project to design open standards for containers.

The objective of this blog post is to deep dive into the various aspcts of OCI aka Open Container Initiative and how Docker fits in there.
