build a container with php/apache

we can search php and apache image on Docker Hub, we will use php:7.0-apache for this demo.

create Dockerfile and src/index.php as below

root@ubunu2004:~/docker_sample# tree
.
├── Dockerfile
└── src
└── index.php
1 directory, 2 files
root@ubunu2004:~/docker_sample# cat  Dockerfile
FROM php:7.0-apache
COPY src/ /var/www/html
EXPOSE 80
root@ubunu2004:~/docker_sample# cat src/index.php
<?php
echo "Hello World!";

build the container
docker build -t hello_world .

run the container
docker run -p 82:80 hello_world
then you can verify it on http://192.168.0.43:82/

if you want mapping the index.php to container, you can start it with
docker run -p 82:80 -v /root/docker_sample/src/:/var/www/html/ hello_world
now if you update index.php, you will get the change immediately on http://192.168.0.43:82/

you can push this image to Docker Hub
