    Hi guys.

    Would you know how to use WORDPRESS_CONFIG_EXTRA as an argument to docker/podman command? Like with usual -e I’ve been trying some variations but am unable to get resulting wp-config.php hold any extra definitions.

    I’m hoping for WP_HOME & WP_SITEURL so such WP would be deployed under a sub-path, eg.: https://some.thing/word

    many thanks, L

    Hi, you pass it like any other env var. Something along these lines works: docker run -e “WORDPRESS_CONFIG_EXTRA=define(‘WP_HOME’, ‘https://some.thing/word’); define(‘WP_SITEURL’, ‘https://some.thing/word’);” … The official image entrypoint appends the value to the end of wp-config.php when the container starts, so it just has to be valid PHP. I find it easier to keep it in a compose file with a block scalar rather than one long -e flag. One heads up for your sub-path setup: once the defines are in place, also make sure your reverse proxy passes the real Host header through, because otherwise WordPress can still build URLs with the container’s internal hostname.
