LinuxKit is a toolkit for building secure, portable, and lean container-based operating systems. Over the past six months, it has gained 75 contributors and seen improvements like support for additional platforms, TPM support, immutable images, and newer kernel versions. Looking ahead, the next six months will focus on stable releases when Containerd 1.0 is available, using LinuxKit as the basis for Docker desktop and cloud editions, and expanding Kubernetes integration and production usage. The LinuxKit Security SIG has also deep dived several security projects and aims to contribute further to upstream Linux security.
