platformservice v41.16.0

PlatformService

PlatformService is a Lumen app that facilitates a bunch of features for our service Letterhead. It is largely responsible for the management of newsletters, and acts as an API gateway for additional services that handle roles, permissions, users, link resolution, pixel tracking, and so on.

Installation

Using Docker and docker-compose

Let's assume that the user already have docker installed, if not please refer to: https://docs.docker.com/engine/ and https://docs.docker.com/compose/

- Navigate to the project root direcotry.
- Be sure you have a .env file already configured.
- Change the DB_HOST variable into the .env as shown:
    DB_HOST=db-platformservice
- Add the following the the .env file:
    NGINX_HOST=<host_name_you_want>
    Examle:  NGINX_HOST=platformservice.com
- Add the <host_name_you_want> to the host file on your OS.
- Run the following command:
    * docker-compose build dev
    * docker-compose up -d
    * docker-compose exec app composer install
    * docker-compose exec php artisan migrate

That's it! Now visit <host_name_you_want>:8080 Ex: http://platformservice.com:8080

If you want to browse the database, connect to: Host: 127.0.0.1 Port: 3305 Username: The user configured on .env Password: The pass configured on .env

Deploy

DigitalOcean

We can deploy PlatformService on DigitalOcean's App Platform. A template "app spec" lives in the .do/ directory. Treat it like a .env.example. It's a little more verbose, but the principle is the same. Rename the service, and swap {VALUE} with the appropriate values in a file named how you like. You can then deploy it using DigitalOcean's doctl CLI with

doctl apps create --spec path/to/spec

If you have doctl installed, your YAML is valid, and you have the appropriate privileges, this will deploy PlatformService to the app platform at a new url, which you can retrieve from doctl or through the browser by logging into DigitalOcean.

On an Ubuntu server

Scheduled tasks and queues

PlatformService relies on a variety of scheduled tasks (or cron jobs) and queues to perform functions behind the scenes. You'll need to be familiar with Lumen and Laravel. The documentation on Queues, Jobs, Tasks, and the like, is really quite good.

Supervisor

In a live environment you'll find that we rely on Supervisor, which runs in the background on an Ubuntu server and manages processes (like queues!) for us. You can find PlatformService's Supervisor configuration file at the root of this repo :) called lumen-queue-platformservice.conf.

1. Place this in /etc/supervisor/conf.d/
2. supervisorctl reread
3. supervisorctl update
4. supervisorcl restart all

Cron

Our tasks and recurring jobs are found in app/console/Kernel.php. In a live environment, to have the server run these you will need to edit your cron sudo crontab -e and add

* * * * * cd /path/to/platformservice && php artisan schedule:run >> /dev/null 2>&1
