-gVisor is a user-space kernel, written in Go, that implements a substantial
-portion of the Linux system surface. It includes an Open Container Initiative
-(OCI) runtime called runsc that provides an isolation boundary between the
-application and the host kernel. The runsc runtime integrates with Docker and
-Kubernetes, making it simple to run sandboxed containers.
