producing themed PDF using Asciinurse (and she will convert your Asciidoc)

In preparation of my current work assignment I have revisited Asciinurse and enabled here to produce PDF.

Asciinurse is my take to separate Asciidoctor and all it’s dependencies into a single docker container image. With Version 1.3.0 I have enabled her to produce themed PDF out of your asciidoc files, simply by running docker run --rm -t -i -v $PWD:/data -v /etc/localtime:/etc/localtime b4mad/asciinurse asciidoctor-pdf -a pdf-style=rh-ra -v myfile.asciidoc

Looking at the command line, -a pdf-style will do the magic trick for you, it selects the theme to be applied by asciidoctor-pdf.

preparing my Atomic App demo for Red Hat Summit

Beside the hands on lab I co-host with some colleagues – @collier_s @nhripps @erikonopen – I have prepared a short demo on #Atomicapp it gives a short context what we are solving and why, additionally there is one slide that explains what a #Nulecule is. 

From the presentation (and github):

  • Application description and context maintained within a single container through extensible metadata
  • Composable definition of complex applications through inheritance and composition of containers into a single, standards-based, portable description.
  • Simplified dependency management for the most complex applications through a directed graph to reflect relationships.
  • Container and orchestration engine agnostic, enabling the use of any container technology and/or orchestration technology

The second part of the demo is the famous #WordPress Atomic App referencing a pre-built #MySQL Atomic App. 
You will find it on the #RedHatSummit channel and/or the #projectatomic channel on YouTube later this month.

super simple build services for docker container images

Over the course of the past three days I build many dozens of containers. I have not been using any container build service like OSBS for that. Finally, I got tired of checking for the correct docker build command in my history and implemented the super simple build service – ssbs.

It consists of two parts:

  • a LABEL within the Dockerfile and
  • a shell alias


I have put LABEL Build docker build --rm --tag goern/wordpress-centos7-atomicapp . in my docker file. And this shell alias to evaluate it alias docker-build='$(grep LABEL Dockerfile | grep Build | cut -d " " -f 3- )'.
