Yii2 advanced app Docker - adding virtual hosts to apache

Yii 2.0 General Discussions
1

I am struggling to get virtual hosts for my advanced app working in Docker. It currently works perfectly in xampp.

I have copied over the following files from GitHub - yiisoft/yii2: Yii 2: The Fast, Secure and Professional PHP Framework. into the corresponding directories in my repo: -

/docker-compose.yml
/backend/Dockerfile
/frontend/Dockerfile

I altered /docker-compose.yml to add in the virtual hosts volume: -

version: "3.2"
services:
	frontend:
		build: frontend
		ports:
		 - 3000:80
		volumes:
		 # Re-use local composer cache via host-volume
		 - ~/.composer-docker/cache:/root/.composer/cache:delegated
		 # Mount source-code for development
		 - ./:/app
		 # virtual hosts
		 - ./apache_conf:/etc/apache2/sites-enabled/
	backend:
		build: backend
		ports:
		 - 4000:80
		volumes:
		 # Re-use local composer cache via host-volume
		 - ~/.composer-docker/cache:/root/.composer/cache:delegated
		 # Mount source-code for development
		 - ./:/app
		 # virtual hosts
		 - ./apache_conf:/etc/apache2/sites-enabled/

In my ./apache_conf/000-default.conf: -

<VirtualHost \*:80>
	ServerName frontend.myapp
	DocumentRoot /app/frontend/web
</VirtualHost>
<VirtualHost \*:80>
	ServerName backend.myapp
	DocumentRoot /app/backend/web
</VirtualHost>

In my Windows hosts file: -

127.0.0.1 frontend.myapp
127.0.0.1 backend.myapp

However, when I run the container, I get “site can’t be reached” when I try both the frontend and backend domains.

Can anyone help me with this? Thanks.

Hi,
please start docker compose in non detach mode and show the logs.
Then share both dockerfile.

VirtualHost directives were wrong…

try to replace

<VirtualHost \*:80>

with

<VirtualHost *:80>

Thanks for your help.

In my container /etc/apache2/sites-enabled/000-default.conf

<VirtualHost *:80>
        ServerName frontend.myapp
        DocumentRoot /app/frontend/web
</VirtualHost>
