runc
runc is a lightweight, portable container runtime that implements the Open Container Initiative (OCI) specification for creating and running containers. It serves as the core component for spawning and managing containers on Linux systems, providing the low-level functionality to execute containerized applications. It is widely used as the default runtime for Docker and other container platforms.
Developers should learn runc when working with container technologies, especially for building custom container runtimes, debugging container execution, or integrating containers into CI/CD pipelines. It is essential for understanding the underlying mechanics of containerization, enabling fine-grained control over container lifecycle and security features like namespaces and cgroups.
