What is the significance of "Pod overhead" in the context of running workloads with different container runtimes (e.g. gVisor or Kata Containers via RuntimeClass)?
Correct! Well done.
Incorrect.
The correct answer is B) Sandboxed runtimes giving stronger isolation via lightweight VMs consume extra resources beyond the container's own request/limit; "Pod overhead" lets the scheduler account for this cost during placement, preventing nodes being over-committed
Correct Answer
Sandboxed runtimes giving stronger isolation via lightweight VMs consume extra resources beyond the container's own request/limit; "Pod overhead" lets the scheduler account for this cost during placement, preventing nodes being over-committed
RuntimeClass can specify a "overhead" field representing the extra resources consumed by the runtime's sandboxing mechanism (beyond the container itself), which the scheduler factors in to avoid overcommitting node resources.
