Description: 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.
