How to cache package manager downloads for docker builds?

If I run composer installfrom my host, I get into the local composer cache:

  - Installing deft/iso3166-utility (1.0.0)
    Loading from cache

However, when creating a container that has in its Dockerfile:

RUN composer install -n -o --no-dev

I load all things, for example:

  - Installing deft/iso3166-utility (1.0.0)
    Downloading: 100%

It was expected, but I would like to avoid it. As with recovery, it will also download everything again.

I would like to have a universal cache for the composer, which I could also use for other docker projects.

I studied this and found an approach for defining a volume in a Dockerfile :

ENV COMPOSER_HOME=/var/composer
VOLUME /var/composer

I added this to my Dockerfileand expected that the files will be downloaded only once, and then it will go to the cache.

, -o composer, -o -o docker build. , .
