Software: The Docker daemon, called dockerd, is a persistent process that manages Docker containers and handles container objects. The daemon listens for requests sent via the Docker Engine API. [22] [23] The Docker client program, called docker, provides a command-line interface (CLI) that allows users to interact with Docker daemons. [22] [24]
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
Through the "rules engine daemon" that can automatically move processes of certain users, groups, or commands to cgroups as specified in its configuration. Indirectly through other software that uses cgroups, such as Docker, Firejail, LXC, [19] libvirt, systemd, Open Grid Scheduler/Grid Engine, [20] and Google's developmentally defunct lmctfy.
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.

The dashboard offers basic controls for common tasks as well as advanced controls for the more technological advanced user; CLI or console management is also possible. The Unraid dashboard is particularly useful flagship feature to users who are new or inexperienced in operating Linux, home servers, NAS, Docker, and more.
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 ...
The basic scheduling unit in Kubernetes is a pod, [54] which consists of one or more containers that are guaranteed to be co-located on the same node. [32] Each pod in Kubernetes is assigned a unique IP address within the cluster, allowing applications to use ports without the risk of conflict. [ 55 ]
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 ().
