I'm getting this error:

WordPress not found in /var/www/html - copying now...
Complete! WordPress has been successfully copied to /var/www/html

That is not an error, that is how it works the first time that it is started with an empty /var/www/html.

@yosifkit But I'm getting No 'wp-config.php' found in /var/www/html, but 'WORDPRESS_...' variables supplied; copying 'wp-config-docker.php' (WORDPRESS_ADMIN_PASSWORD WORDPRESS_ADMIN_USER WORDPRESS_DB_HOST WORDPRESS_DB_NAME WORDPRESS_DB_PASSWORD WORDPRESS_DB_USER WORDPRESS_EMAIL WORDPRESS_INSTALL_TYPE WORDPRESS_SITE_TITLE WORDPRESS_TABLE_PREFIX) error.

Upon looking at wp-config.php, none of the variables were copied:

// ** Database settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define( 'DB_NAME', getenv_docker('WORDPRESS_DB_NAME', 'wordpress') );

/** Database username */
define( 'DB_USER', getenv_docker('WORDPRESS_DB_USER', 'example username') );

/** Database password */
define( 'DB_PASSWORD', getenv_docker('WORDPRESS_DB_PASSWORD', 'example password') );

/**

 * (However, using "example username" and "example password" in your database is strongly discouraged.  Please use strong, random credentials!)
 */

/** Database hostname */
define( 'DB_HOST', getenv_docker('WORDPRESS_DB_HOST', 'mysql') );

/** Database charset to use in creating database tables. */
define( 'DB_CHARSET', getenv_docker('WORDPRESS_DB_CHARSET', 'utf8') );

/** The database collate type. Don't change this if in doubt. */
define( 'DB_COLLATE', getenv_docker('WORDPRESS_DB_COLLATE', '') );

The variables are not embedded into the file anymore -- they get loaded at runtime instead so that changes are applied correctly without any hacky file editing.

[seba-i]

@tianon any way to see what the output looks like, now that its runtime only?
(for debugging: I can see the docker env vars but WP doesn't seem to be picking up on them).

[tianon]

I don't know if WP-CLI has something that would show you the effective configuration, but you should be able to write a wordpress plugin or something like that which does.

Try this method :

chmod 777 -R /opt/wordpress/sites
