How to use this image

Create a Dockerfile in your Lumen project:

FROM bfgasparin/lumen-apache:5-onbuild

Put this file in the root of your app, next to the composer.json.

This image includes the minimum packages for a Lumen project to work. It do not include database libraries or memcache libraries, for example. It's up to you to install these libraries. For example, if you are going to use PostgreSQL as database, you will need to install the libraries and binaries to communicate to PostgreSQL as well as the postgres php extension. You can do it in your Dockerfile:

FROM bfgasparin/lumen-apache:5-onbuild

# Install postgres libraries and headers for C language
RUN apt-get update && apt-get install -y \
        libpq-dev \
        && apt-get clean \
        && rm -rf /var/lib/apt/lists/*

# Install postgres php extension
RUN docker-php-ext-install \
        pdo_pgsql \
        pgsql

This image includes multiple ONBUILD triggers which should cover most Lumen applications. The build will:

• ONBUILD COPY composer.json composer.lock /var/www/html
• ONBUILD RUN composer install --prefer-dist --optimize-autoloader --no-dev --profile -vvv
• ONBUILD COPY . /var/www/html
• ONBUILD RUN rm -Rf tests/
• ONBUILD RUN chown -R www-data:www-data /var/www/html/storage/
• ONBUILD VOLUME /var/www/html/storage

The build also sets the default command to apache2-foreground to start apache2 service.

You can now build and run the Docker image:

$ docker build -t my-lumen-app .
$ docker run --name some-lumen-app -d my-lumen-app

You can test it by visiting http://container-ip in a browser or, if you need access outside the daemon's host, on port 8080:

docker run --name some-lumen-app -p 8080:80 -d my-lumen-app

You can then go to http://localhost:8080 or http://host-ip:8080 in a browser.

How to install more PHP extensions

This images extends the php:7-apache Oficial Image, so it provides two convenient scripts named docker-php-ext-configure and docker-php-ext-install, you can use them to easily install PHP extension. See PHP Oficial Image Repository for more details.

Apache

Apache is configured to provide Authorization header to the request.

Apache is also configured to disable .htaccess support on the application directory to increase its performance.

PHP

PHP is configured to run optimized (for this image to be used in production). You can change php configuration adding a custom php.ini configuration. COPY it into /usr/local/etc/php by adding one more line to your Dockerfile:

FROM bfgasparin/symfony-apache:5-onbuild
COPY config/php.ini /usr/local/etc/php

Configuring Lumen

Lumen is configured using environment variable. So to configure your Lumen application, you can use docker:

$ docker run --name some-lumen-app -e "APP_DEBUG=false" -e "DB_CONNECTION=pgsql" -p 8080:80 -d my-lumen-app

Development

When using this image for development, its a good practice to mount the application source directory from your host into the docker container. When you do that, you may probably overwrite the vendors packages.

If it's yours first time, you will probably need to install the application vendors again:

$ docker exec -u Lumen my-lumen-app composer install --prefer-dist

How to configure PHP for development

This image comes with php-fpm configured to be used in production environment, containing settings which hold security, performance and best practices. To customize the php behavior for development environment, COPY a custom php.ini configuration into /usr/local/etc/php (you can use the $PHP_INI_DIR environment variable) by adding one more line to the Dockerfile above and running the same commands to build and run:

FROM bfgasparin/lumen-apache:5-onbuild
COPY config/php.ini $PHP_INI_DIR

Where config/ contains your php.ini file.
