Run mail gateway in docker

[tmwl]

Hi,
i was trying to run the mail gateway in a docker container. My Dockerfile looks like this (not complete):

FROM debian:buster

ENV DEBIAN_FRONTEND noninteractive

RUN set -ex; \
    \
    apt-get update; \
    apt-get install -y --no-install-recommends \
        wget \
        gnupg1 \
        bzip2 \
        busybox-static \
    ; \
    \
RUN set -ex; \
    \
    echo "postfix postfix/main_mailer_type string Satellite system" > postfixsettings.txt; \
    debconf-set-selections postfixsettings.txt; \
    apt-get install -q -y postfix; \
    wget http://download.proxmox.com/debian/proxmox-ve-release-6.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg; \
    echo deb http://download.proxmox.com/debian/pmg buster pmg-no-subscription >> /etc/apt/sources.list; \
    apt-get update; \
    apt-get install -y \
        proxmox-mailgateway-container \
    ;\
    \
    rm -rf /var/lib/apt/lists/*

but i get this error:

Maybe someone can help me with this problem.

Sorry, but Proxmox Mail Gateway is not meant to be run inside Docker. Please use a real container (LXC) instead, or run inside a VM.

That's unfortunate. It looks like there is only a problem with the database connection. In future releases maybe you can separate installation and initialization. Then you can use a postgres container and connect it with the mail gateway container.
