  1. Challenge

    Install gVisor and Create a containerd Sandbox Configuration

    Install gVisor on both the control plane node and the worker node.

    Create a containerd runtime configuration called runsc on both servers as well.

  2. Challenge

    Create a RuntimeClass for the Sandbox

    Create a RuntimeClass called runsc-sandbox. Configure it to use the runsc containerd configuration.

  3. Challenge

    Move All Pods in the questionablesoft Namespace to the New Runtime Sandbox

    Move all Pods in the questionablesoft namespace to the new runtime sandbox. You will need to delete and re-create the Pods to accomplish this. For convenience, you can find manifest files for these Pods in /home/cloud_user.

    Note: If you wish to compare the sandboxed Pods to a non-sandboxed Pod, there is a non-sandboxed Pod called securicorp-api in the default namespace.
