For Scott K.  per our conversation about enabling https for package management.  I add the following just after FROM on registry-base and comanage-registry-shibboleth-sp-base

// code placeholder

ENV DEBIAN_FRONTEND noninteractive
RUN mkdir /apt-local
COPY *.deb /apt-local/
RUN apt-get -y install /apt-local/*.deb; \
        sed -i 's/http:/https:/g' /etc/apt/sources.list && sed -i 's/bullseye\/updates/bullseye-security/g' /etc/apt/sources.list; \
        apt-get update ;\
        apt-get -y install wget curl openssl ca-certificates apt-utils procps findutils net-tools git vim ; \
       /bin/rm -rf /apt-local

The COPY command is grabbing
apt-utils_2.2.4_amd64.deb  ca-certificates_20211016_all.deb  openssl_1.1.1n-0+deb11u3_amd64.deb
which are necessary for https connections to work.  and then grabbing procps, findutils, net-tools, git, vim is for convenience but nice to have!

Do let me know if you have any questions.
