support/docker/Dockerfile

# This Dockerfile generates the docker image that gets used by Gitlab CI
# To build it (YYYYMMDD.HHMM is the current date and time in UTC):
#   sudo docker build -t buildroot/base:YYYYMMDD.HHMM support/docker
#   sudo docker push buildroot/base:YYYYMMDD.HHMM

# We use a specific tag for the base image *and* the corresponding date
# for the repository., so do not forget to update the apt-sources.list
# file that is shipped next to this Dockerfile.
