I'm trying to set the laravel 5.6 in Docker image, but when executing the command:

 docker run -it --rm  \
     -v $(pwd):/app {user_dockerHub}/docker-laravel \ 
     composer create-project laravel/laravel app

I'm getting the following error:

To enable extensions, verify that they are enabled in your .ini files:
- /etc/php7/php.ini
- /etc/php7/conf.d/00_ctype.ini
- /etc/php7/conf.d/00_curl.ini
- /etc/php7/conf.d/00_dom.ini
- /etc/php7/conf.d/00_json.ini
- /etc/php7/conf.d/00_mbstring.ini
- /etc/php7/conf.d/00_mcrypt.ini
- /etc/php7/conf.d/00_opcache.ini
- /etc/php7/conf.d/00_openssl.ini
- /etc/php7/conf.d/00_pdo.ini
- /etc/php7/conf.d/00_session.ini
- /etc/php7/conf.d/00_tokenizer.ini
- /etc/php7/conf.d/00_xml.ini
- /etc/php7/conf.d/01_mysqlnd.ini
- /etc/php7/conf.d/01_pdo_pgsql.ini
- /etc/php7/conf.d/01_pdo_sqlite.ini
- /etc/php7/conf.d/01_phar.ini
- /etc/php7/conf.d/02_pdo_mysql.ini



You can also run 'php --ini' inside terminal to see which files are used by PHP in CLI mode.

Dockerfile

RUN mkdir -p /app
WORKDIR /app
RUN chmod -R 755 /app
EXPOSE 82 445
CMD ["supervisord", "-c", "/etc/supervisord.conf"]

I have already searched the web, tested possible solutions and did not have a satisfactory result.

If someone has already had this problem and wants to share it, I thank them right away.

Looking calmly, your error is identical to an error reported in your comments reference :

phpunit/php-code-coverage 6.0.7 requires ext-xmlwriter * -> the requested PHP extension xmlwriter is missing from your system.

It is the xmlwriter dependencies that have not been added to your image.

In your Dockerfile , add: php7-xmlwriter in the dependency list and build again. When running the new image will work correctly.
