Docker LEMP:

Docker multi-project setup for LEMP Stack: Linux + Nginx + MariaDB + PHP

You can have multiple virtual host for Nginx like: app1.localhost, app1.localhost etc.

Before start it you need to find your Docker Host Ip and adding it to the Environment variables, it allows you to connect to Mariadb.

Get my docker host ip address

ip -4 addr show docker0 | awk '$1=="inet" {print $2}' | cut -d/ -f1

Result

172.17.0.1

Setting Environment variables

Create a dont env file with the next essencial variables:

DATABASE_HOST: <<Your docker host ip>>
DATABASE_NAME: themariadatabasename
DATABASE_USER: root
DATABASE_PASSWORD: themariadatabsepassword
