研究方向
The issue requests the ability to download the tar artifact created by kaniko during a skaffold build. The user can build the image with tarPath set but cannot retrieve the tar. Investigation should focus on how skaffold handles kaniko pods and whether the tar is stored in the pod's filesystem or elsewhere. Check the kaniko builder code in pkg/skaffold/build/kaniko/ for how the tar archive is handled after the build. Also review any existing comments in the issue for proposed solutions or workarounds. Consider implementing a feature to copy the tar from the kaniko pod using kubectl cp or similar tool.
