How to build and run an Apache container with PHP in a docker

ENVIRONMENT
  • Docker: 18.03.1-ce
  • Host: Windows 10 Pro
INSTRUCTIONS
  •  Create a Dockerfile in your project with the following content:
FROM php:7.0-apache
COPY src/ /var/www/html/
EXPOSE 80
  • Create an src folder to store your website files and folders
  • Create an index.php file inside the src folder as below :
<?php 
echo "Hello World !";

The folder structure at this point would look like this :

folder_structure

  • Build Docker Image using command:
docker build -t phpapache .

build

docker build command downloads the referenced images and creates a new build as per the instructions in the Dockerfile in your local repository.

  • Run docker container using command :
docker run -d --name phpapache-runtime-3 -p 8080:80 -v "$(pwd)/src:/var/www/html/" phpapache

Here we are doing the following :

running the container in the detached mode

naming the container as phpapache-runtime,

mapping the host port 8080 to the container port 80

mounting the src folder in the present working directory in host machine to the /var/www/html/ inside the container. This will allow a real-time change of the website hosted by Apache.

docker_run

 You can list all running containers using command: docker ps

TESTING :
  1. Access the website using url : http://localhost:8080/index.php

indexphp

Next, modify the index.php file in the src directory as below and refresh the page and test again :


<?php
echo "Hello World Changed!";

afterchange

Note:

To mount the host machine folder as a volume in the container, you will first need to enable share drive.

You can do this in docker settings window:

docker_shareddrive
