Fatal error: Uncaught Error: Call to undefined function CommonMark\Parse()

First of all

$ lsb_release -a

$ docker-compose -v
docker-compose version 1.29.2, build unknown

Let’s get to the point

$ docker run php -r 'CommonMark\Parse();'
Fatal error: Uncaught Error: Call to undefined function CommonMark\Parse() in Command line code:1

Maybe some extension is missing?
From what I see from the page PHP: CommonMark\Parse - Manual I think it should be the cmark extension.
Let’s do another test…

$ cat docker-compose.yml 
        build: .

$ cat Dockerfile 
FROM php
RUN docker-php-ext-install cmark

$ docker-compose run php -r 'CommonMark\Parse();'

if custom ./configure arguments are necessary, see docker-php-ext-configure

Some of the above modules are already compiled into PHP; please check
the output of "php -i" to see which modules are already loaded.
ERROR: Service 'php' failed to build : The command '/bin/sh -c docker-php-ext-install cmark' returned a non-zero code: 1

How can I solve?
