Used to create a development (or production) environment of WordPress using the official Docker WP from the store. One huge plus to this if you decide to use it for development, check out the .htaccess file. It rewrites requests to the /wp-content/uploads folder so you don't have to add that to your dev environment :) I opened the MySQL port to …

.htaccess

# ================================================================================
#   Redirects uploads to production.
# ================================================================================
<IfModule mod_rewrite.c>
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^wp-content/uploads/(.*)$ https://www.some-website.com/wp-content/uploads/$1 [R=301,NC,L]
</IfModule>

    RewriteRule . /index.php [L]
