man-docker.sh

#! /bin/sh

# Step 1: checkout docker sources, but make sure you do this
# somewhere in /Users directory because boot2docker can only
# share this path with docker containers

git clone https://github.com/docker/docker.git

# Step 2: build docker image
cd docker/man && docker build -t docker/md2man .

# Step 3: build man pages
docker run -v $(realpath ~)/code/docker-manual/docker/man:/docs:rw -w /docs -i docker/md2man /docs/md2man-all.sh

cp -R man* /usr/share/man/
