Using Docker to get the latest Laravel 5.3, which requires a PHP version I didn't have on my local machine.
We cover using a PHP base Docker image, and adding into it to add tools we need.
We first started trying out installing Laravel on a machine with PHP 5.5 (Laravel 5.3 requires PHP 5.6+).
cd ~/Sites/docker composer create project laravel/laravel my-app dev-develop
This gave us an error, as we'd expect. Rather than spin up a whole VM, I chose to try using Docker.
# This doesn't work, composer is not in the container! docker run --rm -it php:7.0-cli composer --version # This does work, we use my local machine's composer # and make it available to the container docker run --rm -it \ -v $(which composer):/usr/bin/composer \ php:7.0-cli \ composer --version
If we go straight from there, however, we'll still get errors, as composer requires
unzip to be available to get dependencies from GitHub.
So, we create a new
Dockerfile, which will help us add the tools we need to a base PHP image that already had PHP 7 in it.
FROM php:7.0-cli MAINTAINER Chris Fidao RUN apt-get update RUN apt-get install -y zip unzip curl git RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" RUN php composer-setup.php --install-dir=/usr/bin --filename=composer RUN php -r "unlink('composer-setup.php');"
And then we can get Laravel!:
# This doesn't work, composer is not in the container! docker run --rm -it php:7.0-cli composer --version # From dir ~/Sites/docker docker run --rm -it \ -v $(pwd):/opt composer:latest \ composer create-project laravel/laravel /opt/my-app dev-develop
This installs a new Laravel application into the
The last step is to keep using PHP 7 to run Laravel, so we can start hacking on this new project.
We can re-use our
composer container, or use the
php:7.0-cli container - they both have PHP 7 on it.
# From dir ~/Sites/docker/my-app # Note that we're inside of the "my-app" directory! docker run --rm -it \ -p 80:8888 -v $(pwd):/opt composer:latest \ php -S 0.0.0.0:8888 -t /opt/public
If we head to our browser and go to
localhost, we'll see the Laravel 5.3 splash screen - success!
