This script will create an OCI image using buildah, which can be run using Podman.

Build the image

To build the image juste run the Podmanfile script

$ ./Podmanfile
$ podman images

Quick start

$ podman run --rm \
	--name=asciidoctor
	-v $(CURDIR):/data:rw,Z \
	quay.io/tinsjourney/asciidoctor-pdf main.adoc -o engagement-journal.pdf

Where:

• $(CURDIR): This location contains files from your host that need to be accessible by asciidoc-pdf. Should be the directory where your asciidoc file are.
• main.adoc: This is the main asciidoc file
• engagement-journal.pdf: The name of the output pdf.

Usage

To find the right command you just need to display the runlabel.

$ podman container runlabel -p --display run quay.io/tinsjourney/asciidoctor-pdf
Command: /proc/self/exe run --rm --name asciidoctor -v $(CURDIR):/data:rw,Z quay.io/tinsjourney/asciidoctor-pdf:latest main.adoc -o engagement-journal.pdf

Optimize pdf

Asciidoctor PDF also provides a shell script that invokes GhostScript (gs) to optimize and compress the generated PDF with minimal impact on quality. See Optional Scripts on asciidoctor-pdf github page for more information.

In order to use it with the container image, we need to overwrite the entrypoint

$ podman run --rm \
	--name=asciidoctor \
	-v $(CURDIR):/data:rw,Z \
	--entrypoint /usr/local/bin/optimize-pdf /
	quay.io/tinsjourney/asciidoctor-pdf engagement-journal.pdf
