You should probably use pip3 with the --break-system-packages and --no-cache-dir arguments, like:
FROM tryton:7.0
RUN pip3 install --break-system-packages --no-cache-dir trytoncommunity-account-es-facturae trytoncommunity-edocument-es-facturae
Also it is better for production to use a pinned series as the upgrade is not necessary supported by the custom module (which by the way only works for 7.0 series).
And you need to set a name for the tag.
