Who is Linux Containers?
Linux Containers (LinuxContainers.org) provides open source system containers and related tooling for running Linux environments in isolated, lightweight, and manageable instances on a shared kernel.
- Open source system container technologies and projects
- Tools for managing containerized Linux system and application workloads
- Focus on OS-level virtualization using the Linux kernel
- Support for container lifecycle management, orchestration, and configuration
- Community-driven development, documentation, and reference implementations

More About Linux Containers
Linux Containers focuses on system containers, which provide OS-level virtualization that allows multiple isolated Linux environments to run on a single host kernel. These environments behave similarly to separate machines from a user and process perspective, while sharing the underlying Operating System (OS). This model differs from hardware virtualization, which uses hypervisors and full guest operating systems per Virtual Machine (VM).
The organization maintains and coordinates container technologies that use core Linux kernel features such as namespaces, control groups (cgroups), capabilities, and layered filesystems. These kernel constructs provide isolation for process IDS, networking, mounts, users, and resource control. On top of these primitives, Linux Containers projects expose higher-level abstractions for creating, starting, stopping, configuring, and monitoring containers, and for integrating them into existing infrastructure and automation workflows.
In enterprise and institutional environments, Linux Containers offerings are used for workload consolidation, dev/test environments, application sandboxes, and infrastructure services that benefit from near bare-metal performance while retaining isolation. System containers are often deployed on bare-metal servers or virtual machines as building blocks for multi-tenant platforms, hosting environments, and internal Platform-as-a-Service (PaaS) architectures. Their compatibility with standard Linux distributions, init systems, and package managers supports traditional operations models as well as newer cloud-native practices.
From a marketplace perspective, Linux Containers fits into the container infrastructure and OS-level virtualization category, alongside application container platforms. While application containers typically package single processes or microservices, system containers run full Linux systems or complex multi-process workloads. This distinction positions Linux Containers technologies as an option for organizations that want container density and manageability without refactoring applications into microservices or changing existing operating models.
Linux Containers projects integrate with common enterprise infrastructure components such as Software Defined Networking (SDN), storage backends, and identity and access management systems, using standard Linux networking, storage protocols, and authentication mechanisms. The organization’s documentation and tooling cover topics such as container images, security hardening using kernel security modules, and automation through configuration management and orchestration tools. In directories and catalogs, Linux Containers can be categorized under container infrastructure, OS-level virtualization, and systems management for Linux-based data center and cloud platforms.
