The main classes of Docker objects are images, containers, and services. [22] A Docker container is a standardized, encapsulated environment that runs applications. [25] A container is managed using the Docker API or CLI. [22] A Docker image is a read-only template used to build containers. Images are used to store and ship applications. [22] 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. [1]
OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, including containers (LXC, Solaris Containers, AIX WPARs, HP-UX SRP Containers, Docker, Podman), zones (Solaris Containers), virtual private servers (), partitions, virtual environments (VEs), virtual kernels (DragonFly BSD), and jails ...
Proxmox allows deployment and management of virtual machines and containers. [ 7 ] [ 8 ] It is based on a modified Debian LTS kernel. [ 9 ] Two types of virtualization are supported: container-based with LXC (starting from version 4.0 replacing OpenVZ used in version up to 3.4, included [ 10 ] ), and full virtualization with KVM .
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 ().
Microsoft App-V is an additional component requiring licensing for use. Licensing is user-based and is either acquired by licensing Microsoft Desktop Optimization Pack (MDOP) for use on client operating systems, or as part of the Microsoft Remote Desktop Server Client Access License for use on Remote Desktop Servers.
Sun releases Solaris 8 Containers to enable migration of a Solaris 8 computer into a Solaris Container on a Solaris 10 system – for SPARC only. 2008. The first Linux kernel mainline featuring cgroups (developed by Google since 2006) is released, laying a foundation for later technologies like LXC, Docker, Systemd-nspawn and Podman.
