A C library providing a convenient API for managing Linux containers throughout their entire lifecycle.
Libct is a C library that provides a convenient API for managing Linux containers throughout their entire lifecycle. It abstracts low-level container primitives like namespaces, cgroups, and filesystem isolation into a structured interface, allowing frontend programs to easily create, configure, and control containers. The library simplifies container orchestration by handling the complex kernel interactions required for container management.
System programmers and developers building container management tools or orchestration systems who need direct, low-level control over Linux containers without relying on higher-level runtimes like Docker.
Libct offers a lightweight, library-based approach to container management with a clean, consistent API that abstracts away the complexity of Linux kernel interfaces. Unlike heavier container runtimes, it provides fine-grained control over container configuration and lifecycle, making it ideal for custom container orchestration solutions.

Abstracts low-level Linux container primitives like namespaces and cgroups into a structured interface, making container management more accessible without dealing with kernel complexities directly.
Supports various container features including namespaces, cgroup controllers, root filesystems with chroot or pivot_root, and network interface assignment, allowing detailed customization as per the README examples.
All API calls, types, and constants are defined in a single header file (libct.h), simplifying integration into C projects and reducing dependency headaches.
Provides fine-grained control over container lifecycle and configuration, ideal for building custom orchestration tools without the overhead of heavier runtimes like Docker.
Requires manual compilation of dependencies like libnl via git submodules and custom builds, as outlined in the compiling instructions, which can be cumbersome for newcomers.
Relies on a single documentation file (libct.txt) and test examples, which may not cover advanced use cases or provide sufficient guidance for troubleshooting.
Admits limitations such as only one type of session and private area, restricting flexibility compared to more mature container management libraries.
Focused on C and Linux with a smaller community, lacking the extensive tooling, integrations, and support found in projects like runc or LXC.
