With docker-scripts we can have one or more Wordpress containers, and each container can serve one or more sites, as shown in the diagram:

Since all these sites use the ports 80 and 443, we need a reverse HTTP proxy in order to forward each request to the corresponding container that serves that site/domain. The docker-scripts container wsproxy plays this role, using Apache VirtualHost configurations. Not only that, but wsproxy also gets automatically a free LetsEncrypt SSL certificate for each domain/site that it manages, and also redirects automatically all HTTP requests to HTTPS.

All the containers of docker-scripts are placed on the same local network, and wsproxy knows how to access the container of each domain that it manages. So, only the wsproxy container needs to get the ports 80/443 forwarded from the host. The Wordpress containers get their requests from wsproxy through the docker-scripts local network, so they don't need to expose the ports 80/443 to the host or to the outside world.

Each Wordpress container in turn uses Apache VirtualHost configurations to be able to serve several (more than one) sites/domains.

Each Wordpress site needs also a database, and all of them use the docker-scripts container mariadb, which they access through the local network of docker-scripts.

    cd

  2. Install Webserver Proxy:

    ds pull wsproxy

    ds init wsproxy @wsproxy

    cd /var/ds/wsproxy/

    # vim settings.sh # optional

    ds make

    cd

  3. Install MariaDB:

    ds pull mariadb

    ds init mariadb @mariadb

    cd /var/ds/mariadb/

    # vim settings.sh # optional

    ds make

    cd
