Hi folks
I've been trying to get the OE layer index example docker setup in shape,
based upon improvements from myself, Michael and Konrad. For the moment I've
taken most of what Michael and I did (with some fixes and tweaks, and broken up
into smaller patches) and a few pieces of the Dockerfile from Konrad's recent
patch and put it here:
http://git.yoctoproject.org/cgit/cgit.cgi/layerindex-web/log/?h=paule/dockerfixes
Konrad, I know you were a little bit more ambitious with your changes but I
wanted to get something closer to what Michael is using and then we can build
upon it. In particular I haven't yet explored docker-compose as you have,
although it looks like it would make deploying all of this a bit easier.
Let me know what you think.
Hello Paul,
I have attached a patch to reduce the layerindex-web image size further.
Docker image layers are like git objects and RUN commands can only hide
files, not remove them once they have been committed. The pip upgrade
caused the following 'pip install' to fail and was removed.
I recommend docker-compose because much of the information in
docker/README can be captured in a compose yaml file. It handles the
network setup and makes managing shared volumes much simpler.

Subject: [PATCH] Dockerfile: Reduce image size by merging RUN stages together
Docker commits changes after each RUN stage and commands that delete
files must part of the sane RUN command to actually reduce image size.
Debian stretch contains pip 9.0.3 and the upgrade to 10 caused pip
install to fail.
