How do I get this to work in a docker environment - missing ext-zip extension

I am stuck with these errors for days and I have tried quite a couple of Dockerfile configurations.

Versions

• PHP version: 7.3
• Laravel version: ^6.2
• Package version: ^3.1

Description

Exact errors

  Problem 1
    - Installation request for phpoffice/phpspreadsheet 1.11.0 -> satisfiable by phpoffice/phpspreadsheet[1.11.0].
    - phpoffice/phpspreadsheet 1.11.0 requires ext-zip * -> the requested PHP extension zip is missing from your system.
  Problem 2
    - phpoffice/phpspreadsheet 1.11.0 requires ext-zip * -> the requested PHP extension zip is missing from your system.
    - maatwebsite/excel 3.1.19 requires phpoffice/phpspreadsheet ^1.10 -> satisfiable by phpoffice/phpspreadsheet[1.11.0].
    - Installation request for maatwebsite/excel 3.1.19 -> satisfiable by maatwebsite/excel[3.1.19].

  To enable extensions, verify that they are enabled in your .ini files:
    -
    - /usr/local/etc/php/conf.d/docker-php-ext-bcmath.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-exif.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-gd.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-pcntl.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-pdo_mysql.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-sodium.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
