using a custom alpine base image for my custom package #4114
Description
Hello!
I want to build a pkg that runs lldpd (https://pkgs.alpinelinux.org/package/edge/community/x86/lldpd)
from the documentation, I added 'lldpd' to tools/alpine/packages and built my custom alpine image with make build, that created an image I can see in my local docker images:
linuxkit/alpine 89cad7757a4a4957f711437c93df5ac890bd30f7-arm64 455525acc948 17 minutes ago 1.79GB
I have created a lldpd folder in pkg/ , with its build.yml and created a Dockerfile with:
FROM linuxkit/alpine:89cad7757a4a4957f711437c93df5ac890bd30f7-arm64 AS mirror
RUN mkdir /out
RUN apk add --no-cache --initdb -p /out lldpd
FROM scratch
ENTRYPOINT []
CMD []
WORKDIR /
COPY --from=mirror /out/ /
when I try to build my pkg image, it fails when trying to reference my custom base alpine image
linuxkit pkg build --hash 111 pkg/lldpd --force --platforms linux/arm64

I understand that docker is trying to ge the image from docker.io, but I want to instead use my locally built alpine image,
if i run (inside pkg/lldpd) docker build ., the image is built as desired, but there is something going on between linuxkit and docker build causing the issue
thanks!
