Container Runtime
A container runtime creates and manages isolated processes using container configuration and filesystem images. Low-level runtimes implement execution, while higher-level services can also handle image retrieval, networking, and container lifecycle management.
Also known as: OCI runtime
Why it matters
Containerized jobs require a functioning execution service as well as image-building tools.
Practical example
A working Docker CLI alone is insufficient if the runner cannot reach a compatible container service.
