Build a Laravel Docker Image Using a Dockerfile
Laravel is a modern web application framework for artisans.
Introduction
Building a dockerfile for a Laravel
application does not need to be tedious. The good folks at
The Coding Machine have created several base images that we can leverage.
Prerequisites
You need to have the following setup on your development machine to proceed with this tutorial
Let’s get started
Create a new laravel project
> laravel new laravel-app
and navigate into the laravel-app
directory and execute the following command:
> php artisan serve
Try it out in your browser localhost:8000
Before we create our Dockerfile
lets first create a .dockerignore
file:
file: laravel-app\.dockerignore
node_modules/
public/hot/
public/storage/
storage/*.key
vendor/
.env.backup
.phpunit.result.cache
Homestead.json
Homestead.yaml
npm-debug.log
yarn-error.log
Dockerfile
docker-compose.yml
docker-compose.yaml
**.git
.idea
**.gitignore
**.gitattributes
**.sass-cache
We can now create our Dockerfile
:
file: laravel-app\Dockerfile
ARG PHP_EXTENSIONS="intl pdo_mysql pdo_pgsql bcmath"
FROM thecodingmachine/php:7.4-v3-slim-apache as php_base
LABEL maintainer "Julius Krah <juliuskrah@gmail.com>"
ENV TEMPLATE_PHP_INI=production
COPY --chown=docker:docker . /var/www/html
RUN composer install --quiet --optimize-autoloader --no-dev
FROM node:10 as node_dependencies
WORKDIR /var/www/html
ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=false
COPY --from=php_base /var/www/html /var/www/html
RUN npm set progress=false && \
npm config set depth 0 && \
npm install && \
npm run prod && \
rm -rf node_modules
FROM php_base
ENV APACHE_DOCUMENT_ROOT=/var/www/html/public
COPY --from=node_dependencies --chown=docker:docker /var/www/html /var/www/html
Build and tag the image:
> docker build -t laravel-app .
Time to test our image with a container
> docker run --rm --name laravel -e DB_CONNECTION=pgsql -p 8000:80 laravel-app
NOTE: You can replace all options in the .env
file with environment variables on the command line e.g.
-e DB_CONNECTION=pgsql
Conclusion
An optional step is to tag and upload your image to docker hub:
> docker tag laravel-app <username>/laravel-app
> docker login
> docker push <username>/laravel-app
