Laravel Heroku Deploy

This Laravel 7+ package allows you to configure your Heroku Review Apps instance for Laravel applications. You can manage custom domains using Cloudflare, apply Automated Certificate Management (ACM) with Lets Encrypt and update Config Vars using Heroku's postdeploy and pr-predestroy script events.

Installation

Require this package with composer:

composer require codegreencreative/laravel-heroku-deploy

Configuration

The command below will add a new heroku-deploy.php config file in your config folder.

php artisan vendor:publish --tag="heroky_deploy_config"

    // Heroku Platform API token, learn more here:
    // https://devcenter.heroku.com/articles/authentication
    'heroku_token' => env('HEROKU_DEPLOY_HEROKU_TOKEN', null),
    // Cloudflare token, get yours here:
    // https://dash.cloudflare.com/profile/api-tokens
    'cloudflare_token' => env('HEROKU_DEPLOY_CLOUDFLARE_TOKEN', null),

    // {
    //     "mydomain.com": ["id", "account", "support", "policies"]
    // }
    'cloudflare_zones' => json_decode(env('HEROKU_DEPLOY_ZONES', '[]'), true),
    // You can attach addons from other applications
    // {
    //      "addon_id": "confirming_app (id or name)"
    // }
    'heroku_addon_attachments' => json_decode(env('HEROKU_DEPLOY_ADDON_ATTACHMENTS', '[]'), true),
    // Enable automated certificate management in Heroku for each subdomain
    'enable_acm' => env('HEROKU_DEPLOY_ENABLE_ACM', true)
];

.env

Example .env entry.

HEROKU_DEPLOY_HEROKU_TOKEN=addyourtokenehere
HEROKU_DEPLOY_CLOUDFLARE_TOKEN=addyourtokenehere
HEROKU_DEPLOY_ZONES="{\"mydomain.com\": [\"id\", \"account\", \"support\"]}"
# Optional
# This connects Heroku Postgres database or Heroku Redis, for example
HEROKU_DEPLOY_ADDON_ATTACHMENTS="{\"xxxx-xxxx-xxxx-xxxx-xxxx\": \"xxxxxxxxx\"}"
HEROKU_DEPLOY_ENABLE_ACM=false

app.json

Add the postdeploy and pr-predestroy commands to your app.json file.

{
    "environments": {
        "review": {
            "scripts": {
                "postdeploy": "php artisan heroku:postdeploy",
                "pr-predestroy": "php artisan heroku:pr-predestroy"
            }
        }
    }
}

Config Vars

Two additional config vars are added/updated depending on your own configuration, APP_BASE_DOMAIN and APP_URL. The first domain you define in HEROKU_DEPLOY_ZONES will be considered your base/primary domain as you can only have one. The first subdomain of your first domain is considered your APP_URL. We also use the pull request number to keep review apps unique. Pull request numbers are provided by Heroku as environment variables.

For example, these will be added to your environment automatically:

APP_BASE_DOMAIN=pr-125.mydomain.com
APP_URL=https://id.pr-125.mydomain.com

Should you not enable ACM, session cookies will be set to insecure.

SESSION_SECURE_COOKIE=false

Session cookies will be created with a unique name.

SESSION_COOKIE=PR125_SID

Any other config vars that need to be added can be done so in your Heroku pipeline.

Bug Reporting

If Bugsnag is installed, exceptions will be reported in Bugsnag.

Todo

• Check logging config for errorlog | bugsnag
• Redirect default herokuapp.com subdomain to root domain
