Enable Object Caching

Once the initial site configuration performed, navigate to Plugins, activate WP-FFPC and click Settings. Set the following minimal configuration options:

• Cache Type/Select Backend: PHP Memcached
• Backend Settings/Hosts: memcached:11211
• Backend Settings/Authentication: username: Empty
• Backend Settings/Authentication: password: Empty
• Backend Settings/Enable memcached binary mode: Activated

Updating

Because the docker-compose levegare persistent volume in the Wordpress root directory, its required to open a session in the cli container in order to run the command wp core update.

Interactive

Open a terminal session in the cli container.

WP_CLI=$(docker ps -qa -f ancestor=fjudith/wordpress:cli)
docker container exec -it ${WP_CLI} bash

Run the following commands to update the application engine, the plugins and themes.

wp core update
wp plugins update --all
wp theme update --all

Non-interactive

Run the following commands

WP_CLI=$(docker ps -qa -f ancestor=fjudith/wordpress:cli)
docker container exec ${WP_CLI} bash -c 'wp core update && wp plugins update --all && wp theme update --all'
