Issues

Unable to edit files

make perm

cannot open 'wp/wp-content/debug.log' for reading: No such file or directory

Normally in wp/wp-config.php you should have near line 80 define('WP_DEBUG', true);. Replace it by the following:

// Show debug logs in wp-content/debug.log
define('WP_DEBUG', true);
define( 'WP_DEBUG_DISPLAY', false );
define( 'WP_DEBUG_LOG', true );

make logs-sql shows nothing

MariaDB has to restart to load the configuration file db-conf/enable-general-logs.cnf.

make down up

WordPress asks for a FTP server

Add the following line to wp-config.php:

// Don't download through FTP
define('FS_METHOD', 'direct');

Other commands

Stop the stack:

docker-compose down

Start the stack and see logs in terminal:

docker-compose up
