Two containers in one Pod must exchange intermediate files quickly during a request. What is the most direct built-in approach?
Select an answer to reveal the explanation.
Short Explanation
Containers in one Pod already share the apartment. Drop a shared emptyDir “kitchen counter” between them and pass files across—no separate Pods or public downloads required.
Full Explanation
Containers in a Pod share volumes declared on the Pod spec. An emptyDir volume is the usual ephemeral shared filesystem for co-located helpers. Splitting into multiple Pods adds network and PVC coordination complexity for what is inherently local scratch sharing. hostPath and Ingress are poor defaults for this in-Pod exchange.
