⁠What is Composer?

Composer is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.

⁠Is it better than official Composer images⁠?

I'm using official image's script as reference, and major PHP versions (5.6, 7.0, and 7.1) as Base Image. This image also use hirak/prestissimo⁠ for faster downloads.

⁠How to use this image

Basic usage using current user.

docker run --rm \
    --user $(id -u):$(id -g) \
    --volume /local/path:/project \
    herloct/composer[:tag] [<options>]

For example, to install dependencies.

docker run --rm \
    --user $(id -u):$(id -g) \
    --volume /local/path:/project \
    herloct/composer install --ignore-platform-reqs

If you want to cache composer for faster install/update, just add volume to /composer/cache.

docker run --rm \
    --user $(id -u):$(id -g) \
    --volume /local/path:/project \
    --volume /local/composer:/composer/cache \
    herloct/composer install --ignore-platform-reqs

⁠Volumes

• /project: Your PHP project directory.
• /composer/cache: Composer cache directory.
