A PDF-render sidecar needs scratch space that must disappear when the Pod is deleted. Which volume type fits best?
Select an answer to reveal the explanation.
Short Explanation
emptyDir is a whiteboard in the meeting room: great while the meeting (Pod) is going, wiped when everyone leaves. Perfect scratch space for a PDF sidecar.
Full Explanation
emptyDir provides ephemeral storage that exists as long as the Pod runs on a node and is deleted when the Pod goes away. It can be mounted by multiple containers in that Pod. PVCs and hostPath persist beyond typical scratch needs or couple to nodes; ConfigMaps are for configuration data, not binary scratch pads.
