Followup to this post.

I’ve encountered a few difficulties today, when my Wercker setup started failing while installing the few extra packages needed to deploy this blog.

I’m not sure exactly what happened, but I suspect that this is a case of the debian docker image being cached too aggressively on Wercker, which made packages installation more difficult (trying to access the wrong version or something). Anyway, that was always a hack, and Docker images should be as self-contained as possible.

Therefore, I built my own “box” (in Wercker lingo), that contains everything that’s needed to run the Hugo build, and GitHub pages deployment.

The image itself is very simple:

FROM ubuntu:15.10
MAINTAINER Yann Hodique <>

RUN apt-get update -q \
  && DEBIAN_FRONTEND=noninteractive apt-get install -qy git openssh-client python-pygments curl \
  && apt-get clean \
  && rm -rf /var/lib/apt

On the blog side, it now looks like this:

box: sigma/blog-builder:v0.1.3
    - arjen/hugo-build@1.8.1
    - slack-notifier:
        url: $SLACK_URL
        username: wercker
    - lukevivier/gh-pages@0.2.1:
        token: $GIT_TOKEN
        basedir: public

Next step will be to figure out why my first Alpine-based attempt ended up deploying something completely absurd…

Looks like there’s no end to yak shaving.
