== Containers

If you prefer not having to install Rust & Cargo and have Podman or Docker installed, you may prefer to run a containerized
version of {cli}. This chapter explains how to proceed.

{prj} is designed to work at the repository level and you need to mount your repo as `/repo` into the {prj} container.

    podman run --rm -it -v $PWD:/repo paritytech/prdoc --help

----
    ENGINE=podman
    DOC_PATH="$PWD/tests/data/some"
    $ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc --help
    $ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc scan --all
    $ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc check
    $ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc load
----

NOTE: The container image is working by default in `/repo` so it makes it simpler if you mount your repo there as shown
above.

=== Run

 podman run --rm -it -v $PWD:/repo paritytech/prdoc --help

----
    ENGINE=podman
    DOC_PATH="$PWD/tests/data/some"
    $ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc --help
    $ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc scan --all
    $ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc check
    $ENGINE run --rm -it -v $DOC_PATH:/repo paritytech/prdoc load
----

NOTE: The container image is working by default in `/repo` so it makes it simpler if you mount your repo there as shown
above.

Commands can end up quite lengthy so you may like to set an alias:

[subs="attributes+"]
----
    alias {prj}='podman run --rm -it -v $PWD:/repo paritytech/prdoc'
----

After setting this alias, you may use {cli} by simply invoking the {cli} command:

[subs="attributes+"]
----
    {prj} --version
----

This is out of the scope of this documentation but note that you can just invoke `{prj} check` and expect it to work in
your repo as long as it contains a valid configuration file and schema. Check out the <<Configuration>> chapter for more
details.

=== Build

You can pull the container image from `paritytech`/{cli} or build you own:

[subs="attributes+"]
----
    podman build -t {prj} .
