The Open Container Initiative (OCI) is a Linux Foundation project, started in June 2015 by Docker, CoreOS, and the maintainers of appc (short for "App Container") to design open standards for operating system-level virtualization ().
The main classes of Docker objects are images, containers, and services. [23] A Docker container is a standardized, encapsulated environment that runs applications. [26] A container is managed using the Docker API or CLI. [23] A Docker image is a read-only template used to build containers. Images are used to store and ship applications. [23] A ...
Singularity is a free and open-source computer program that performs operating-system-level virtualization also known as containerization. [4]One of the main uses of Singularity is to bring containers and reproducibility to scientific computing and the high-performance computing (HPC) world.
In software engineering, containerization is operating-system–level virtualization or application-level virtualization over multiple network resources so that software applications can run in isolated user spaces called containers in any cloud or non-cloud environment, regardless of type or vendor.

Lmctfy is the release of Google's container tools and is free and open-source software subject to the terms of Apache License version 2.0. The maintainers in May 2015 stated their effort to merge their concepts and abstractions into Docker's underlying library libcontainer and thus stopped active development of lmctfy. [2]
Various container software use Linux namespaces in combination with cgroups to isolate their processes, including Docker [17] and LXC. Other applications, such as Google Chrome make use of namespaces to isolate its own processes which are at risk from attack on the internet. [18] There is also an unshare wrapper in util-linux. An example of its ...
Docker, a project automating the deployment of applications inside software containers; Apache Mesos, a large-scale cluster management platform based on container isolation; Operating system-level virtualization implementations; Proxmox Virtual Environment, an open-source server virtualization management platform supporting LXC containers and KVM
Container Linux provides no package manager as a way for distributing payload applications, requiring instead all applications to run inside their containers. Serving as a single control host, a Container Linux instance uses the underlying operating-system-level virtualization features of the Linux kernel to create and configure multiple containers that perform as isolated Linux systems.
