Laravel Envoy Deploy

This repository includes an Envoy.blade.php script that is designed to provide a basic "zero-downtime" deployment option using the open-source Laravel Envoy tool.

Requirements

This Envoy script is designed to be used with Laravel 5 projects and can be used within the Laravel root, or downloaded separately and included in your Laravel project.

Installation

Your must have Envoy installed using the Composer global command:

composer global require "laravel/envoy"

Standalone

To download and run out-with your Laravel project, clone this directory and do a composer install.

Laravel

To use within an existing Laravel 5 project, you simply need to download the Envoy.blade.php file to your project root:

wget https://raw.githubusercontent.com/papertank/envoy-deploy/master/Envoy.blade.php

Setup

Config

Envoy Deploy uses DotEnv to fetch your server and repository details. If you are installing within a Laravel project, there will already be a .env file in the root, otherwise simply create one.

The following configuration items are required:

• DEPLOY_SERVER
• DEPLOY_REPOSITORY
• DEPLOY_PATH

For example, deploying the standard Laravel repository on a Forge server, we might use:

[email protected]
DEPLOY_REPOSITORY=https://github.com/laravel/laravel.git
DEPLOY_PATH=/home/forge/example.com
DEPLOY_HEALTH_CHECK=https://example.forge.com

The DEPLOY_PATH (server path) should already be created in your server and must be a blank directory.

Host

Envoy Deploy uses symlinks to ensure that your server is always running from the latest deployment. As such you need to setup your Apache or Nginx host to point towards the host/current/public directory rather than simply host/public.

For example:

server {
    listen 80;
    server_name example.com;
    root /home/forge/example.com/current/public;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }

    location ~ /\.ht {
        deny all;
    }
}

Usage

Init

When you're happy with the config, run the init task on your local machine by running the following.

envoy run init

You only need to run the init task once.

The init task creates a .env file in your root path (from your .env.example file), so make sure and update the environment variables appropriately. Once you have run the init task, you should proceed to run the deploy task (below).

Deploy

Each time you want to deploy simply run the deploy task on your local machine in the repository direcory

envoy run deploy

You can specify the Laravel environment (for artisan:migrate command) and git branch as options

envoy run deploy --branch=develop --env=development

Deploy with Cleanup

If you could like to deploy your repository and cleanup any old deployments at the same time, you can run

envoy run deploy --cleanup

Or alternatively, if you need to:

This will run the deploy script and then delete any old deployments older than 48 hours, limiting the number deleted to 5.

You can also run the cleanup script independently (without deploying) using

envoy run deployment_cleanup

Health Check

If you would like to perform a health check (for 200 response) after deploying, simply add your site's URL in the .env file:

DEPLOY_HEALTH_CHECK=https://example.forge.com

Rollback

To rollback to the previous deployment (e.g. when a health check fails), you can simply run

envoy run rollback

Commands

envoy run init

Initialise server for deployments

Options
    --env=ENVIRONMENT        The environment to use. (Default: "production")
    --branch=BRANCH          The git branch to use. (Default: "master")

envoy run deploy

Run new deployment

Options
    --env=ENVIRONMENT        The environment to use. (Default: "production")
    --branch=BRANCH          The git branch to use. (Default: "master")
    --cleanup                Whether to cleanup old deployments

envoy run deployment_cleanup

Delete any old deployments, leaving just the last 4.

envoy run rollback

In case the health check does not work, you can rollback and it will use the previous deploy.

How it Works

Your $path directory will look something like this after you init and then deploy.

20170910131419/
current -> ./20170910131419
storage/
.env

As you can see, the current directory is symlinked to the latest deployment folder

Inside one of your deployment folders looks like the following (excluded some laravel folders for space)

app/
artisan
boostrap/
composer.json
.env -> ../.env
storage -> ../storage
vendor/

The deployment folder .env file and storage directory are symlinked to the parent folders in the main (parent) path.

Disclaimer

Before using on live server, it is best to test on a local VM (like Laravel Homestead) first.

Changes

V2.2

• Added health_check task and config.
• Added rollback task to update current to previous deployment.
• Updated cleanup to delete old deploys and leave last 4.
• Removed deployment_optimize task (no longer needed for Laravel 5 projects).
• Updated deployment_composer to use --prefer-dist --optimize-autoloader options.

V2.1 - Updated init to only initialize (rather than deploy).

v2.0 - Switched to using DotEnv (removing envoy.config.php) and cleaned up tasks/stories.

v1.0.1 - Added cleanup task and deploy_cleanup macro after changing cleanup command.
