放入 /bin 时，Distroless 映像无法安装二进制文件

Question

I'm trying to build a Distroless image for Lume . It's based on a pre-built image from Deno , so I only have to install the lume executable and make it available in the Distroless image — that's my understanding.

This is what I have so far:

FROM docker.io/denoland/deno:debian-1.17.1 AS bin

RUN set -o errexit -o nounset; \
  deno run --allow-all https://deno.land/x/lume@v1.4.2/install.ts

FROM docker.io/denoland/deno:distroless-1.17.1

COPY --from=bin /usr/local/bin/lume /bin/lume

CMD ["lume"]

After running docker build --tag lume-distroless:latest./ , I would expect docker run -it lume-distroless:latest lume --version to successfully be able to use the lume executable and print the version, for instance...but I'm getting this instead:

$ docker run -it lume-distroless:latest lume --version 
error: Found argument 'lume' which wasn't expected, or isn't valid in this context

USAGE:
    deno [OPTIONS] [SUBCOMMAND]

For more information try --help

Any clues what am I missing here?

I would accept a Pull Request with the solution against this issue as well.

The image you built is configured to execute the deno executable on container startup.

To run lume , you have two options:

1. Use an ENTRYPOINT command in your Dockerfile, like ENTRYPOINT ["/bin/lume"] , then build a new image. You can then use docker run -it lume-distroless:latest --version

2. Overwrite the entrypoint when starting a container, like docker run -it --entrypoint=/bin/lume lume-distroless:latest --version
