There is a handy WordPress plugin for that, but of course, it needs redis to be installed and configured properly. That's the part I struggled with as it could not connect to my redis container.

Normally, Redis should work out-of-the-box with WordPress as long as it is accessible via localhost:6379.

The thing is, in a docker setup the redis instance is accessible via its container name.

So in the above example, in order for WordPress to find it, you need to modify the constant WP_REDIS_HOST to "redis" in your wp-config.php file.

define('WP_REDIS_HOST', 'redis');
define('WP_REDIS_PORT', '6379');
    
i did it and works with default theme, but when i try to install hub theme (themeforest.net/item/hub-responsiv...) i got a message like the link has expired.
but if  i use a solution like easyengine.io, which also works under docker, i can install the theme without problem, what am i doing wrong?
          
Looks like this recipe may longer work. I am running into an issues today with the latest plugin release. FYI:
