Xdebug

For performance optimization, there's a separate Dockerfile.debug file for building php image with xdebug installed.

How to use this image

Basic usage can be found on php's official docker hub repository.

Port

The image exposes port 9000 for outside access.

Notes:

1. While the image is building, it will run the following command:

   mkdir /root/.ssh && echo "StrictHostKeyChecking no " > /root/.ssh/config

   This command will allow you to mount your host's ssh keys if your app will use a private repository package. You can ignore this if you're not planning to use a private repository, it's safe!

Tagging

PHP

docker build -t $vendor/docker-php:$version .

With Xdebug

docker build -f Dockerfile.debug -t $vendor/docker-php:xdebug-$version .

Try it out!

docker run --rm -it $vendor/docker-php:$version php -v
