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/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/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/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/).
