What is gvisor?
gVisor is an application kernel that provides strong isolation for containers by implementing a Linux-like interface in userspace using memory-safe Go. It addresses the security limitations of traditional containers, where a single kernel vulnerability can lead to container escape, by creating a secure sandbox between applications and the host OS. The project includes an OCI-compatible runtime called `runsc` that integrates with Docker and Kubernetes.
Developers and operators running untrusted or potentially malicious code in containers who need stronger isolation than traditional containers provide. Infrastructure teams managing multi-tenant container environments where security boundaries are critical.
gVisor offers VM-like security with container-like performance by running as a userspace application kernel. Unlike syscall filters or wrapper tools, it implements a complete Linux interface in memory-safe Go, providing defense-in-depth against kernel vulnerabilities while maintaining compatibility with existing container ecosystems.
