Arc

Bootstrap your new Laravel projects with a highly configurable, production ready Docker environment. Automated build, test and deploy to Kubernetes using Travis CI

Overview

Arc is a simple Laravel package to add the ultimate Docker environment for the majority of your applications. Built upon the amazing ContinuousPipe Dockerfiles, this package will add the correct Dockerfile, Docker Compose and configurations into your Laravel project.

Additionally - if selected, it can also add a Continuous Integration & Continuous Deployment configuration to work with Travis CI and Kubernetes.

The Docker configuration provides the following:

• PHP 7.4 (Configurable for 5.6, 7.0, 7.1, 7.2, 7.3, 7.4)
• NodeJS 11 inc NPM
• NGINX
• MySQL 8
• REDIS 6
• ConfD templating
• SupervisorD for process management
• Configurable queue workers
• Auto start Laravel Horizon processes
• Auto start CRON
• Easily create a CRON only container. Useful for zero downtime deployments to a Kubernetes cluster
• Configure the entire infrastructure with environment variables.

CI/CD Configuration contains the following:

• Travis CI YAML configuration
• Build and Push your Docker image to Docker Hub
• Automated BASH file & Dockerfile linting
• Automated PHP CodeSniffer, PHPMD & PHPStan static code analysis
• Automated PHP Unit tests
• Configure Kubernetes cluster context via the Kubectl tool
• Configure and deploy your application to Kubernetes with the use of Helm & Helm Charts

Requirements

This package is intended for new Laravel 6 projects.

Installation

Require the package in your project

    composer require richdynamix/arc

Run the installer

    php artisan arc:install

You will be prompted to choose if you want CI/CD configurations.

    Would you like a Travis CI and K8s CD configuration? (yes/no) [no]:

Once complete the installer will remove Arc as a composer dependency.

Please Note: If you choose to use the CI/CD configurations then there are some local environment variables that are required before you can run the containers

    export DOCKER_USERNAME=myUsername
    export DOCKER_REPO=my-repo
    export TAG=latest

    export GITHUB_TOKEN=1234567890 # optional

Run the Container

    docker-compose up

Continuous Integration and Deployment

Required environment variables to be added to your Travis CI repository settings -

Static Code Analysis

• PHP CodeSniffer has been configured with a phpcs.xml file that will be in the root of your project. This will follow PSR2 coding styles within your app folder only.
• PHPMD has been configured to use a ruleset.xml file within the root of your project that follows best practices.
• PHPStan has been configured on the lowest possible level 0. If you wish to increase this level you may modify the tools/docker/usr/local/share/container/plan.sh file at the function do_phpstan

You may use your phpcs.xml and ruleset.xml file to configure your IDE such as PHPStorm to automatically check your code during development

From within the container, you may run any of your static code analysis tools at any time using the following commands:

• container phpcs
• container phpmd
• container phpstan

Additionally, you can run container phpunit to run your test suite within the container.

Connecting to the Web Container

As part of the Arc configurations there is a simple bash script added to the root of your project which allows you to call -

    ./ssh web

This is simply a wrapper script for convenience. Under the hood it's simply calling docker exec -it web bash

Addtionally, you may swap the web argument for any of the container names i.e. ./ssh database, ./ssh redis

Configuration

Arc is nothing more than a way to automatically copy the correct Docker configuration into your Laravel project. While you may have come across several Laravel based Docker environments, none of them cover the production ready setup that the ContinuousPipe Dockerfile provides.

ContinuousPipe Dockerfile offers an extremely flexible and solid infrastructure setup using a simple system of ConfD for templates and SupervisorD for controlling the start of services. The contents of tools/docker/etc and tools/docker/usr are copied into the container at build time which means that we can influence any environment variable and configuration.

Rather that explain all the functions and environment variables available to Arc, it is easier to point you to the documentation for the parent images:

• PHP NGINX - The direct parent of the Arc Docker file. By default, it uses PHP 7.4, but you can change this within the Arc Dockerfile to match your needs. (Available versions are 5.6, 7.0, 7.1, 7.2, 7.3, 7.4)
• Ubuntu 16.04 - This is the base image which the PHP image extends. This sets up all the ConfD and SupervisorD configuration.

To manipulate your environment you can add values for any of the environment variables for any of the above. Additionally, there are a few specific to Arc which are all defined in tools/docker/usr/local/share/env/20-arc-env.

Credits

This package would not have been possible would it not have been for the amazing work of the ContinuousPipe team. Also, a special thanks to Samuel for the introduction of ContinuousPipe and Kubernetes. His ability to teach Docker concepts has been of great value. A huge thanks to Kieren for his attention to detail and everlasting patience when helping me to understand the ContinuousPipe Dockerfiles and setup.
