Docker Setup for CI/CD

Docker is a powerful tool for setting up a replicable environment for your project. Below is a specific example to use eQual with Docker using an official PHP image.

Setup

Go ahead and install Docker. On Windows, it comes with Docker Compose, which automates the deployment process.

Dockerfile

The Dockerfile is used to build an image with additional requirements. Here's an example using eQual with a PHP-Apache image:

FROM php:7.3-apache
COPY . /var/www/html
RUN docker-php-ext-install pdo_mysql mysqli \
    && chown -R www-data:www-data /var/www \
    && cp /etc/apache2/mods-available/rewrite.load /etc/apache2/mods-enabled/
WORKDIR /var/www/html

docker-compose.yml

The docker-compose.yml file is used to deploy containers. Here's an example:

version: '3'
services:
  localhost:
    build:
      context: .
      dockerfile: .docker/Dockerfile
    image: todolist
    ports:
      - 80:80
    links:
      - mysql
  mysql:
    image: mysql:5.7
    environment:
      MYSQL_DATABASE: equal

To launch the containers:

docker-compose up -d

Automating the Process & Database Initialization

To automate the setup process, you can use a script to build the Docker image, deploy the containers, and initialize the database.

Example script:

docker build --file .docker/Dockerfile -t todolist .
docker-compose up -d
sleep 10
docker exec -ti localhost /bin/bash .docker/init.sh

The init.sh script inside the container:

php run.php --do=init_db
php run.php --do=init_package --package=core
