Problem installing in docker container

[SalahAdDin]

I'm trying to make a Dockerfile for install it, i'm getting this error now:

Removing intermediate container 9981adb8e100
Step 12 : RUN composer install
 ---> Running in b878cfa19a0c

  Problem 1

    - facebook/webdriver 1.4.0 requires ext-zip * -> the requested PHP extension zip is missing from your system.

  To enable extensions, verify that they are enabled in your .ini files:
    - 
    - /usr/local/etc/php/conf.d/docker-php-ext-pdo_mysql.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
ERROR: Service 'master' failed to build: The command '/bin/sh -c composer install' returned a non-zero code: 2

This is my Dockerfile:

FROM php:7-fpm

RUN apt-get update > /dev/null \
    && apt-get install -yyq \
    git \
    curl \
    unzip \
    > /dev/null \
    && docker-php-ext-install \
    pdo_mysql \
    iconv \
    pdo \
    > /dev/null \
    && docker-php-ext-enable \
    pdo_mysql \
    iconv \
    pdo \
    > /dev/null \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

RUN php composer-setup.php
RUN php -r "unlink('composer-setup.php');"

RUN mv composer.phar /usr/local/bin/composer

WORKDIR ~
RUN git clone -q https://github.com/zeeshanu/opus.git opus
WORKDIR opus
ADD .env /opus/.env
# TODO: Make posible change branches before install
#active_version=$(git status | head -1)
#if [ "$active_version" != "HEAD detached at $version" ]; then
#    echo "Switching to version $version ..."
#    git fetch -q
#    git checkout -q $version
#fi

RUN composer install

@SalahAdDin You need to enable ext-zip php extension in your php.ini file.

Yes, i did it, it solve, but i have a new problem:

Step 13/15 : RUN php artisan migrate

  [ErrorException]                                                             
  file_get_contents(/var/www/html/~/opus/.env): failed to open stream: No suc  
  h file or directory 

I added the three final commands:

RUN php artisan migrate
RUN php artisan key:generate
RUN php artisan db:seed

What happen here?
