runc Description

runc is a command-line interface utility designed to create and manage containers in accordance with the OCI specification, but it is limited to Linux environments. For compilation, it requires Go version 1.17 or higher, and to activate seccomp features, libseccomp must be installed on your system. The tool offers optional build tags that allow for the inclusion of various functionalities, many of which are activated by default. Currently, runc allows its test suite to be executed through Docker, and simply typing `make test` initiates this process. Although there are additional make targets available for testing outside of a container, this practice is discouraged since the tests assume permission to read and write files freely. You can also specify individual test cases using the TESTFLAGS variable, or focus on a particular integration test with the TESTPATH variable; for rootless integration tests, the ROOTLESS_TESTPATH variable should be used. It’s important to remember that runc serves as a foundational tool rather than one intended for end-user interaction, making it more suitable for developers who need lower-level container management capabilities. Ultimately, understanding its purpose and use cases is essential for effective application.
