[READ-ONLY] Docker image for building Read the Docs documentation (mainly) for PHP projects

Read the Docs Docker image

Docker image for building Read the Docs documentation (mainly) for PHP projects.

Usage

Run the following commands in order to build the documentation:

$ docker run --rm --interactive --tty --volume $PWD:/doc webplates/readthedocs
$ # You are now in the docker image
$ make html
$ make spelling

Alternatively you can run the commands directly from the host without entering the container shell:

$ docker run --rm --tty --volume $PWD:/doc webplates/readthedocs make html
$ docker run --rm --tty --volume $PWD:/doc webplates/readthedocs make spelling

There are also simple shortcuts for the two commands above:

$ docker run --rm --tty --volume $PWD:/doc webplates/readthedocs build
$ docker run --rm --tty --volume $PWD:/doc webplates/readthedocs check

Last, but not least there is a watch command to watch for changes:

$ docker run --rm --tty --volume $PWD:/doc webplates/readthedocs watch

Note about permissions

Unless configured otherwise Docker containers run processes with root user. Furthermore the root user inside containers is also not "mapped" to any other user on host machines by default, although it is possible.

These facts usually end up in permission issues on the host machine (build artifacts are owned by root).

Therefore it's a good idea to manually override the UID and GID when running the containers:

$ docker run --rm --tty --volume $PWD:/doc --user $(id -u):$(id -g) webplates/readthedocs ...

Shell support

Typing the above commands is not really convenient. With a simple alias you can simplify the executed commands:

alias doc='docker run --rm --tty --interactive --volume $PWD:/doc --user $(id -u):$(id -g) webplates/readthedocs'

(Put this in your shell startup script: ~/.bashrc, ~/.zshrc, etc)

Then the commands again:

$ doc build
$ doc check
$ doc watch
