runc has been solid, why change it up?

Wait, are we really switching all Pods to gVisor? Sounds risky.

Just created a RuntimeClass named sandboxed. Easy peasy!

Not sure if it's worth the performance hit, though.

I vaguely remember something about annotations in the RuntimeClass definition. Do we need to include those for gVisor?

I feel a bit uncertain about updating all Pods in the namespace. Did we cover how to do that with a command or a YAML file?

This seems similar to a practice question we did on setting up different runtime handlers. I hope I can recall the steps correctly.

I think I remember how to create a RuntimeClass, but I'm not entirely sure about the exact syntax for using runsc.

This seems pretty straightforward. I'll create the RuntimeClass, then update the Pods in the server namespace to use the new RuntimeClass. Shouldn't be too difficult as long as I follow the steps carefully.

I'm a little confused by the context here. Does the cluster already have the runsc runtime handler configured, or do I need to set that up first? I'll need to double-check the requirements before proceeding.

Okay, I think I've got this. First, I'll create the RuntimeClass resource with the runsc runtime handler. Then I'll update the Pod spec for the Pods in the server namespace to use that RuntimeClass.

Hmm, I'm a bit unsure about the steps here. I'll need to review the containerd documentation on how to set up and configure the additional runtime handler.

This looks straightforward. I'll start by creating the RuntimeClass for the runsc runtime handler, then update the Pods in the server namespace to use that RuntimeClass.

Okay, let's see. The label of the object could have been changed, so that's definitely a possibility. And if it's a custom object, Data Loader may not be the best tool to use.

I'm a bit confused on this one. I'm not sure if the deficits should be reported as organization costs or capitalized and amortized. I'll have to review my notes.

I think I saw a question like this in our study materials. My gut says it's true, because minimizing software does help with security.
