Dockerfile.mlatclient

# This container is meant to be used as a build/download container for Wiedehopf's mlat-client
# it uses debian:bookworm-slim as basis
# ----------------------------------------------------------------------------------------
# HOW TO USE IN YOUR Dockerfile:
# 1. Create a downloader image like this:
# FROM ghcr.io/sdr-enthusiasts/docker-baseimage:mlat-client as downloader
#
# 2. In your target image, start your RUN command like this:
# RUN --mount=type=bind,from=downloader,source=/,target=/downloader set -x && \
#
# 3. In your target image in that same RUN command, make sure to add this to the APT install list:
# KEPT_PACKAGES+=(python3-pkg-resources) && \
#
# 4. Also in the same RUN command for your target image, do this:
# tar zxf /downloader/mlatclient.tgz -C / && \
# ----------------------------------------------------------------------------------------
