Enhancements to Windows Containers

Everyone, I have created a github issue list for getting Windows Containers on par with linux containers:

Here are the issues I documented:

  • Syscall/capability-scoped restriction policy for process-isolated containers (seccomp/capabilities parity) #649 — Syscall/capability-scoped restriction policy for process-isolated containers (seccomp/capabilities parity)
  • True PID namespace isolation for process-isolated containers (server silos) #650 — True PID namespace isolation for process-isolated containers (server silos)
  • CimFS-backed overlay mount performance parity with Linux overlayfs for container image layers #651 — CimFS-backed overlay mount performance parity with Linux overlayfs for container image layers
  • Decouple container base image version from host OS version for process-isolated containers #652 — Decouple container base image version from host OS version for process-isolated containers

Please check them out and upvote them. We need to make Windows containers as capable as Linux containers.

    First thank you for the feedback and thank you for the well-articulated details. I replied on each with at least an initial response and I'll also make sure our engineering manager and team see these so they can monitor and weigh-in as resonable.
