Docker clients connect to registries to download ("pull") images for use or upload ("push") images that they have built. Registries can be public or private. The main public registry is Docker Hub. Docker Hub is the default registry where Docker looks for images. [22] [26] Docker registries also allow the creation of notifications based on ...
In distributed computing, a single system image (SSI) cluster is a cluster of machines that appears to be one single system. [1] [2] [3] The concept is often considered synonymous with that of a distributed operating system, [4] [5] but a single image may be presented for more limited purposes, just job scheduling for instance, which may be achieved by means of an additional layer of software ...
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 ...
BAC – an executable image for the RSTS/E system, created using the BASIC-PLUS COMPILE command [17] BPL – a Win32 PE file created with Delphi or C++Builder containing a package. Bundle – a Macintosh plugin created with Xcode or make which holds executable code, data files, and folders for that code.
Originally, LXC containers were not as secure as other OS-level virtualization methods such as OpenVZ: in Linux kernels before 3.8, the root user of the guest system could run arbitrary code on the host system with root privileges, just as they can in chroot jails. [9]
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.
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.
Should the guest system become unusable (through virus attack, accidental system destruction, etc.), the user can delete the overlay and use an earlier emulated disk image. QEMU can emulate network cards (of different models) that share the host system's connectivity by translating network addresses, effectively allowing the guest to use the ...
