Execution takes too long for "Unpacking rootfs as cmd COPY"

[zhouya2010]

Actual behavior
Creating a custom kaniko image on k8s using the following Dockerfile when execute "Unpacking rootfs as cmd COPY" takes too long:

Dockerfile:

FROM python:3.8
WORKDIR /app
COPY ./main.py ./main.py
COPY ./requirements.txt ./requirements.txt

RUN pip install --no-cache-dir -r requirements.txt 

CMD python main.py

It took nearly 10 minutes at "Unpacking rootfs as cmd COPY ./main.py ./main.py requires it.":

[2024-04-27T17:02:07Z] Cmd: workdir

Expected behavior
should be executed quickly

Thanks for filing this @zhouya2010. Would you mind elaborating the time took with docker since it is checked off Please check if the build works in docker but not in kaniko
