php-laravelHow do I create a Docker image for a Laravel application using PHP?

Creating a Docker image for a Laravel application using PHP is easy.

1. First, create a Dockerfile with the following content:

FROM php:7.2-apache

# Install dependencies
RUN apt-get update && apt-get install -y \
    libzip-dev \
    zip \
    unzip

# Enable Apache mod_rewrite
RUN a2enmod rewrite

# Install PHP extensions
RUN docker-php-ext-install pdo_mysql zip

# Copy our application code
COPY . /var/www/html/

# Set the working directory
WORKDIR /var/www/html

# Expose port 80
EXPOSE 80

2. Then, build the image using the docker build command:

docker build -t laravel-app .

3. Finally, run the container:

docker run -d -p 80:80 laravel-app

The image should be now created and the Laravel application should be running.

Parts of the code explained:

• FROM php:7.2-apache: This line specifies the base image to use for the Docker image.
• RUN apt-get update && apt-get install -y: This command installs the necessary packages for the application.
• RUN a2enmod rewrite: This command enables the Apache mod_rewrite module.
• RUN docker-php-ext-install pdo_mysql zip: This command installs the PHP extensions needed for the application.
• COPY . /var/www/html/: This command copies the application code into the container.
• WORKDIR /var/www/html: This command sets the working directory for the container.
• EXPOSE 80: This command exposes port 80 to the host machine.
