# Should be the same as folder
podName=docker-wordpress

# VirtualHost address
hostRule=wordpress.docker.localhost

# Database credentials
dbName=exampledatabase
dbUser=exampleuser
dbPass=examplepass

# Time Zone
timeZone=Asia/Jerusalem

Network settings

The stack is divided into two networks, backend and frontend.

the idea behind splitting the stack into two networks is to block the access of the reverse proxy to the backend containers.

both networks are unique and will be named with stackname_networname such as:

  • docker-wordpress_backend
  • docker-wordpress_frontend

after running docker-compose up you need to connect your reverse proxy to your new frontend network: you can do that manually using:

  • docker network connect docker-wordpress_frontend PROXY_CONTAINER_NAME

if you are using my Traefik setup there is a ‘connect.sh’ script included that will connect all your frontend networks to your Traefik container.
