How to use it

Just run:

docker run -it -v <your directory>:/documents/ asciidoctor/docker-asciidoctor

It will be directly mapped with /documents of the container.

Once started, you can use Asciidoctor commands to convert AsciiDoc files you created in the directory mentioned above. You can find several examples below.

• To run Asciidoctor on a basic AsciiDoc file:

  asciidoctor sample.adoc
  asciidoctor-pdf sample.adoc
  asciidoctor-epub3 sample.adoc

• To run AsciiDoc on an AsciiDoc file that contains diagrams:

  asciidoctor -r asciidoctor-diagram sample-with-diagram.adoc
  asciidoctor-pdf -r asciidoctor-diagram sample-with-diagram.adoc
  asciidoctor-epub3 -r asciidoctor-diagram sample-with-diagram.adoc

• To use Asciidoctor Confluence:

  asciidoctor-confluence --host HOSTNAME --spaceKey SPACEKEY --title TITLE --username USER --password PASSWORD sample.adoc

• To use Asciidoctor reveal.js with local downloaded reveal.js:

asciidoctor-revealjs sample-slides.adoc
asciidoctor-revealjs -r asciidoctor-diagram sample-slides.adoc

• To use Asciidoctor reveal.js with online reveal.js:

asciidoctor-revealjs -a revealjsdir=https://cdnjs.cloudflare.com/ajax/libs/reveal.js/3.9.2 sample-slides.adoc
asciidoctor-revealjs -a revealjsdir=https://cdnjs.cloudflare.com/ajax/libs/reveal.js/3.9.2 -r asciidoctor-diagram sample-slides.adoc

• Batch mode. You can use it in a "batch" mode

  docker run --rm -v $(pwd):/documents/ asciidoctor/docker-asciidoctor asciidoctor-pdf index.adoc

How to contribute / do it yourself ?

Requirements

You need the following tools:

• A bash compliant command line

• GNU make

• bats installed and in your bash PATH

• Docker installed and in your path

How to build and test ?

• "bats" is used as a test suite runner. Since the ability to build is one way of testing, it is included.

• You just have to run the bats test suite, from the repository root:

  make test

Include test in your build pipeline or test manually

You can use bats directly to test the image, optional you can use a custome image name:

# If you want to use a custom name for the image, OPTIONAL
export DOCKER_IMAGE_NAME_TO_TEST=your-image-name
bats tests/*.bats

Deploy

The goal of "deploying" is to have the Docker image available with the right "Docker tag" in the DockerHub.

As a matter of trust and transparency for the end-users, the image is rebuilt by the DockerHub itself by triggering a build. This only works under the hypothesis of a minimalistic variation between the docker build in the CI, and the docker build by the Dockerhub.

The following environment variables are required to be set: DOCKERHUB_SOURCE_TOKEN and DOCKERHUB_TRIGGER_TOKEN. Their values come from a DockerHub Trigger URL: https://hub.docker.com/api/build/v1/source/${DOCKERHUB_SOURCE_TOKEN}/trigger/${DOCKERHUB_TRIGGER_TOKEN}/call/.

You might want to set these variables as "secret" values in your CI to avoid any leaking in the output (as curl output for instance).
