In computing, Podman (pod manager) is an open source Open Container Initiative (OCI)-compliant [2] container management tool from Red Hat used for handling containers, images, volumes, and pods on the Linux operating system, [3] with support for macOS and Microsoft Windows via a virtual machine. [4]
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.
The docker compose CLI utility allows users to run commands on multiple containers at once; for example, building images, scaling containers, running containers that were stopped, and more. [30] Commands related to image manipulation, or user-interactive options, are not relevant in Docker Compose because they address one container. [31]
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 ...
Docker, a project automating the deployment of applications inside software containers; Apache Mesos, a large-scale cluster management platform based on container isolation; Operating system-level virtualization implementations; Proxmox Virtual Environment, an open-source server virtualization management platform supporting LXC containers and KVM
The OCI organization includes the development of runc, which is the reference implementation of the runtime-spec, [7] [8] a container runtime that implements their specification and serves as a basis for other higher-level tools. runc was first released in July 2015 as version 0.0.1 [9] and it reached version 1.0.0 on June 22, 2021.
Vagrant is a source-available software product for building and maintaining portable virtual software development environments; [5] e.g., for VirtualBox, KVM, Hyper-V, Docker containers, VMware, Parallels, and AWS. It tries to simplify the software configuration management of virtualization in order to increase development productivity.
