Docker Documentation

This directory contains the Docker user manual in the Markdown format. Do not edit the man pages in the man1 directory. Instead, amend the Markdown (*.md) files.

Generating man pages from the Markdown files

The recommended approach for generating the man pages is via a Docker container using the supplied Dockerfile to create an image with the correct environment. This uses go-md2man, a pure Go Markdown to man page generator.

Building the md2man image

There is a Dockerfile provided in the docker/docs/man directory.

Using this Dockerfile, create a Docker image tagged docker/md2man:

docker build -t docker/md2man .

Utilizing the image

Once the image is built, run a container using the image with volumes:

docker run -v /<path-to-git-dir>/docker/docs/man:/docs:rw \
-w /docs -i docker/md2man /docs/md2man-all.sh

The md2man Docker container will process the Markdown files and generate the man pages inside the docker/docs/man/man1 directory using Docker volumes. For more information on Docker volumes see the man page for docker run and also look at the article [Sharing Directories via Volumes] (https://docs.docker.com/use/working_with_volumes/).
