What are Red Hat OpenShift sandboxed containers?
Red Hat OpenShift sandboxed containers, based on the Kata Containers open source project, provide an Open Container Initiative (OCI)-compliant container runtime using lightweight virtual machines (VMs) running your workloads in their own isolated kernel. This contributes an additional layer of isolation to Red Hat’s defense-in-depth strategy.
Features & benefits
Isolated developer environments and privileges scoping
Legacy containerized workload isolation
Multi-tenancy and resource sharing (CI/CD jobs, CNFs, etc.)
Additional isolation with native Kubernetes user experience
