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

Please check if this error is seen when you use --cache flag |
no |
| Please check if your dockerfile is a multistage dockerfile | no |
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
In my case, when add file to .dockerignore, if the Dockerfile use this file, it would cause the COPY to get stuck.
For example, when a makefile accidentally appears in the .dockerignore file and make is used in the Dockerfile.
