chisel does not generate correct image for Ubuntu 24.04?

[flashdma]

Hello!

I'm using the below Dockerfile:

ARG UBUNTU_RELEASE=24.04

# Stage 1
FROM golang as chisel

RUN apt-get update \
    && DEBIAN_FRONTEND=noninteractive apt-get install -y ca-certificates git \
    && apt-get clean -y \
    && rm -rf /var/lib/apt/lists/*

RUN go install github.com/canonical/chisel/cmd/chisel@latest

# Stage 2
FROM ubuntu:${UBUNTU_RELEASE} AS installer
COPY --from=chisel /go/bin/chisel /bin/

RUN apt-get update \
    && DEBIAN_FRONTEND=noninteractive apt-get install -y ca-certificates git \
    && apt-get clean -y \
    && rm -rf /var/lib/apt/lists/*

ARG UBUNTU_RELEASE

WORKDIR /rootfs

RUN chisel cut --release ubuntu-${UBUNTU_RELEASE} --root /rootfs coreutils_bins
RUN find /rootfs/

# Stage 3
FROM scratch
COPY --from=installer [ "/rootfs/", "/" ]
WORKDIR /usr/bin
CMD [ "ls" ]

If I build it and run, then I get the below error:

exec /usr/bin/ls: no such file or directory

If I change UBUNTU_RELEASE parameter to 22.04 in the Dockerfile, then everything works as expected. Am I doing something incorrectly or there is a problem with Ubuntu 24.04 support?

Hiya!

So, to run these binaries, the glibc libraries are needed. While you are actually installing them, docker can't find it in 24.04 because there are no /lib/ or /lib64/ paths in the rootfs. In 22.04, those paths are created while installing the libc6 and other library slices. But in 24.04, the libraries are installed in /usr/lib/ and base-files is the package which symlinks /lib/ to /usr/lib/.

Install the base-files_base slice too and things should work. You can get away with only installing the library paths from base-files_lib slice if you do not want all the paths from the base slice.

Let me know if it works. Cheers!

Thank you very much! I added base-files_lib slice and it works now!
