Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. [5] The service has both free and premium tiers. The software that hosts the containers is called Docker Engine. [6] It was first released in 2013 and is developed by Docker, Inc. [7]
Proxmox Virtual Environment (Proxmox VE or PVE) is a virtualization platform designed for the provisioning of hyper-converged infrastructure. Proxmox allows deployment and management of virtual machines and containers .
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 ...
By default, Alpine running in this mode will only load a few key packages, but a tool called LBU (Alpine Local Backup) [21] is made available that allow changes in this boot configuration to be written to a special file called an APK overlay file (usually shortened to apkovl), a tar.gz file that by default stores a copy of all files in /etc ...
In computing, cp is a command in various Unix and Unix-like operating systems for copying files and directories.The command has three principal modes of operation, expressed by the types of arguments presented to the program for copying a file to another file, one or more files to a directory, or for copying entire directories to another directory.
Solaris Containers (including Solaris Zones) is an implementation of operating system-level virtualization technology for x86 and SPARC systems, first released publicly in February 2004 in build 51 beta of Solaris 10, and subsequently in the first full release of Solaris 10, 2005.
By default, cmp is silent if the files are the same; if they differ, the byte and line number at which the first difference occurred is reported. cp — copy files. dd — convert and copy a file. du — estimate file system usage (space used under a particular directory or files on a file system). df — report free disk space.
Though there are some examples of such file formats (e.g. Microsoft Windows's DLL files), most container formats are specialized for specific data requirements. For example, since audio and video streams can be coded and decoded with many different algorithms, a container format may be used to provide the appearance of a single file format to ...
