A Docker image is a read-only template used to build containers. Images are used to store and ship applications. [22] A Docker service allows containers to be scaled across multiple Docker daemons. The result is known as a swarm, a set of cooperating daemons that communicate through the Docker API. [22] Registries: A Docker registry is a ...
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 ().
Docker, Inc. is an American technology company that develops productivity tools built around Docker, which automates the deployment of code inside software containers. [1] [2] Major commercial products of the company are Docker Hub, a central repository of containers, and Docker Desktop, a GUI application for Windows and Mac to manage containers.
Container clusters need to be managed. This includes functionality to create a cluster, to upgrade the software or repair it, balance the load between existing instances, scale by starting or stopping instances to adapt to the number of users, to log activities and monitor produced logs or the application itself by querying sensors.
They need to provide fast and reliable storage for databases, root images and other data used by the containers. In addition to the landscape, the Cloud Native Computing Foundation (CNCF), has published other information about Kubernetes Persistent Storage including a blog helping to define the container attached storage pattern.
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 ...
Using other enterprise container solutions like Docker in HPC systems would require modifications to the software. [35] Docker containers can be automatically converted to stand-alone singularity files which can then be submitted to HPC resource managers. [36] Singularity seamlessly integrates with many resource managers [37] including ...
