Docker - how to set up Apache + PHP in docker-compose.yml - php

Question

I use this to set up nginx for PHP:
nginx:
image: nginx:latest
ports:
- 8080:80
volumes:
- ./code:/code
- ./site.conf:/etc/nginx/conf.d/site.conf
links:
- php
php:
image: php:7-fpm
volumes:
- ./code:/code
But how about Apache? How can I set up Apache + PHP in docker-compose.yml?
Following this guide:
version: '2'
services:
php:
build: php
ports:
- "80:80"
- "443:443"
volumes:
- ./php/www:/var/www/html
Error:
ERROR: In file './docker-compose.yml' service 'version' doesn't have any configuration options. All top level keys in your docker-compose.yml must map to a dictionary of configuration options.
Any ideas? I'm on Xubuntu 16.04.
EDIT:
After managing to upgrade docker-compose to 1.9, I try with this file below:
version: '2'
services:
php:
build: php
expose:
- 9000
volumes:
- ./php/www:/var/www/html
apache2:
image: webdevops/apache:latest
args:
- PHP_SOCKET=php:9000
volumes:
- ./php/www:/var/www/html
ports:
- 80:80
- 443:443
links:
- php
Error:
$ sudo docker-compose up -d
Building php
ERROR: Cannot locate specified Dockerfile: Dockerfile
Docker is such as pain!
Any ideas how to fix this?

Answer 1

I would choose webdevops dockerized apache, because it has simple configuration:
version: '2'
services:
php:
build: php
expose:
- 9000
volumes:
- ./php/www:/var/www/html
apache2:
image: webdevops/apache:latest
args:
- PHP_SOCKET=php:9000
volumes:
- ./php/www:/var/www/html
ports:
- 80:80
- 443:443
links:
- php

Answer 2

Since the example above does not work, here is a different approach:
docker-compose.yml
version: '3.1'
services:
php:
image: php:apache
ports:
- 80:80
volumes:
- ./php/www:/var/www/html/
Launch the server with
docker-compose up

Answer 3

We need to create a new folders /php/www in current path
Create a file under php folder save as "Dockerfile" which contains as below without quote
"FROM php:5.6-apache
RUN docker-php-ext-install mysqli"
Copy your docker-compose.yml file in your current folder where your "php" folder has.
Create a sample file "index.php" under www folder (/php/www/index.php)
Run in command prompt docker-compose up -d
Open your browser type "localhost" you can see your sample file results.
Note: Above steps as per above mentioned docker-compose.yml file.

Answer 4

You can check this question.
If you use build instead of image, then you need "Dockerfile". Dockerfile would be use as configuration file for building image.
You maybe miss part in guide, where you should create file with name "Dockerfile" inside directory "php". Directory "php" must be in the same directory, where your "docker-compose.yml". In "docker-compose.yml" you have this line.
build: php
The line mean, that configuration file (by default: "Dockerfile") is inside of directory "php". So you should create directory "php" and file "Dockerfile" inside of it.
This is "Dockerfile" from your guide.
FROM php:5.6-apache
RUN docker-php-ext-install mysqli
docker-compose.yml reference version 2
Dockerfile reference

Answer 5

I found an elegant way to dynamically configure the ports and other parameters: In apache2's configuration files you can reference environment variables.
#/etc/apache2/ports.conf
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default.conf
#APACHE_HTTP_PORT_NUMBER:80
#APACHE_HTTPS_PORT_NUMBER:443
Listen ${APACHE_HTTP_PORT_NUMBER}
<IfModule ssl_module>
Listen ${APACHE_HTTPS_PORT_NUMBER}
</IfModule>
<IfModule mod_gnutls.c>
Listen ${APACHE_HTTPS_PORT_NUMBER}
</IfModule>
you can set the variables in Dockerfile or docker-compose.yml

Answer 6

You can set a directory with diferente Dockerfiles an declare in each service:
...
image: php:custom
build:
context: .
dockerfile: ./dockerfiles/Dockerfile-php
...

I have created a working example of PHP, APACHE, MYSQL, and PHPMYADMIN for PHP developers. You may find it useful if you need the original old-school working style. Please note that I am using port 8080 for my website and port 8081 for PHPMyAdmin. You can change these as you like.
