DAPS in a Container

DAPS is OpenSUSE’s “DocBook Authoring and Publishing Suite” that is used to build documentation for SUSE and OpenSUSE. It actually requires A LOT of dependencies when being installed and for that reason alone, it’s actually better to run it in a container. This is my image and how I use it.

docker run -v ~/myproject/:/home/user jsevans/daps:latest daps -d DC-project epub

Command Breakdown:

docker run – Run the command in the container:

-v ~/myproject/:/home/user – Maps a local directory called ~/myproject to a directory in the container called /home/user. /home/user is the default directory that is used by the daps command, so it is best to map this directory rather than needing any extra command line components.

jsevans/daps:latest – This is the image that I’ve created. It is based on OpenSUSE Tumbleweed but it is stable enough for this use. However, it is a large image ~1.2GB due to the number of dependencies.

daps -d DC-project epub – This is the actual command line argument for creating an EPUB ebook using DAPS. I use Asciidoc as my markup language since I don’t really want to learn docbook.

My Dockerfile:

FROM opensuse/tumbleweed
MAINTAINER Jason Evans <jsevans@opensuse.com>

RUN zypper refresh
RUN zypper --non-interactive in daps git

ENV HOME /home/user
RUN useradd --create-home --home-dir $HOME user \
&& chown -R user $HOME

WORKDIR $HOME
USER user

CMD [ "/usr/bin/daps" ]
