How the wordpress stack works

HAProxy on front-end takes requests from users.

WordPress in Docker image based on PHP-FPM + NGINX comes with installed and enabled WP-CLI, nginx-helper, redis-cache, HyperDB plugins.

As a database is used MariaDB in StandAlone configuration with Redis as object cache

In db (MariaDB) service
  1. Click Scale
  2. Choose hosts for slaves
  3. Click Scale service

To scale a WordPress service, you need to scale blog service (Docker) and follow the next steps:

  1. Open a blog service
  2. Click Scale
  3. Choose hosts you want to use for new blog containers
  4. Click Scale service
There is nothing else needs to do. Load balancer works in Sticky session mode by default and balances PHP-FPM containers. HyperDB plugin is already configured and works well with MasterSlave configuration.
