nerdctl: build fails to include basic commands such as COPY

[bwdmr]

Actual Behavior

containerd api does not interpret the dockerfile correctly

Steps to Reproduce

FROM ubuntu:20.04

# Ensure necessary utilities are installed
RUN apt-get update && apt-get install -y coreutils

# Create a non-root user
RUN useradd -m -s /bin/bash dev

COPY ./entrypoint.sh /entrypoint.sh
RUN chown dev /entrypoint.sh

USER dev
WORKDIR /home/dev

# Ensure /dev/null exists
#RUN mknod -m 666 /dev/null c 1 3

# Set entrypoint with explicit path
ENTRYPOINT ["/usr/bin/tail", "-f", "/dev/null"]

disable kubernetes.
enable docker: success
disable kubernetes
enable containerd: success
enable kubernetes
enable containerd: fail

Result

i cant tell what fails. it just stops working if kubernetes runs. and works if not.

Expected Behavior

the containerd api to interpret the dockerfile correctly.

if you wondering. entrypoint is just #/bin/bash echo hello
here the commands for easy reproduction:

• nerdctl build -t test .
• nerdctl run --rm -it --entrypoint="sh" test -c "ls /entrypoint.sh"

@bwdmr We need additional information to do anything further. Please capture both the exact commands you run and the error messages you get from nerctl build and/or nerdctl run!

Can you also enable debug logging (on the Troubleshooting page) and after you reproduce the failure, collect and attach the logs?

And, are you running the nerdctl build command always from the same directory, and is the directory somewhere under your home directory?

closed. i rebuilt and can confirm it works as described by you.
thanks for the quick reply.
