docker-compose up -d

Nos da un error por ip6 de php-fpm, se soluciona así:

docker-compose exec wordpress sed -i 's/listen = \[::\]:9000/listen = 9000/g' /etc/php/7.3/fpm/pool.d/www.conf

Instalamos wordpress:

docker-compose exec -u 1000 wordpress divi-dev setup

URL:       http://local.divi-dev.site
Username:  divi-dev

local.divi-dev.site apunta a nuestra ip local 127.0.0.1

Ya podemos entrar en:
