How to use it

Just run:

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

Docker maps your directory with /documents directory in the container.

After you start the container, you can use Asciidoctor commands to convert AsciiDoc files that 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

To convert files in batch:

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. Optionally, you can specify a custom 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 for deploying is to make the Docker image available with the correct Docker tag in Docker Hub.

As a matter of trust and transparency for the end-users, the image is rebuilt by Docker Hub 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 Docker Hub.

Deploying the image requires setting the following environment variables: DOCKERHUB_SOURCE_TOKEN and DOCKERHUB_TRIGGER_TOKEN. Their values come from a Docker Hub 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).
