KaunasPHP v.52: Simple dockerized PHP application

README.md

Run simple PHP application in docker

• Install docker
• Download example files: (Dockerfile, index.php)
• Run in terminal:

docker build . -t kaunasphp-example
docker run -p 8080:80 kaunasphp-example

This will build docker container named/tagged kaunasphp-example. Docker client will download all necessary files by the configuration in Dockerfile. . is the name of current path where Dockerfile exists.

Second line runs container (tagged as kaunasphp-example) itself. 80 port is usually already used in many computers, so forwarding host 8080 port to container 80.

After those commands you should see:

Hello from docker. PHP version: 7.2.11

when opened http://127.0.0.1:8080/ in a browser

Useful commands

docker ps to list running containers

Dockerfile

FROM php:7.2-apache

COPY . /var/www/html/

index.php

<?php
echo 'Hello from docker. ';
echo 'PHP version: ' . phpversion();
