An open-source, next-generation container runtime (runc).
Works below Docker / Containerd (no need to learn new tools).
Empowers containers to run software such as systemd, Docker, Kubernetes, and legacy apps, seamlessly and securely.
No need to learn new tools. Use Docker and Kubernetes as usual.
Microservices, Systemd-in-Docker, Docker-in-Docker, Kubernetes-in-Docker, etc. Plus legacy apps too.
Use Docker and Kubernetes as usual to deploy more secure and powerful containers. Sysbox works under the covers. No need to learn new tools.
With Sysbox, all containers are strongly isolated via Linux user namespace (root in the container maps to an unprivileged user on the host).
Fast & Efficient
Unmatched speed & efficiency: Deploy a 10-node K8s cluster in under 2 minutes and with only 1GB storage overhead!

Use simple Docker run commands and container images that you fully control. No need for complex images, host mounts, or custom container entrypoints.
Easily preload container or pod images using a simple Dockerfile or Docker commit.
Run Sysbox containers along-side regular containers, without conflict.
Sysbox is designed with a simple principle:
Any software that runs in a VM should run in a container, seamlessly and with strong isolation.
No need for complex Docker commands, images, entrypoints, or unsecure containers.
