I think this use case would be effectively served through a combination of:

• Dynamic resource allocation
• Karpenter node management

I can see how its important; however, getting the design right (or even good enough to not have frustrations) will take some work.

My org is very interested in seeing this come to fruition. One of the issues we run into with Nitro Enclaves is random page size allocations; we are supposed to be able to guarantee any arbitrary Huge Page size, but AWS doesn't respect it properly on node provision. We have multiple open tickets with them and I can link findings back here when it becomes appropriate.

For what it's worth, for our nitro enclave usage the main thing missing is the custom resource support, i.e. https://github.com/aws/karpenter-core/issues/751
