How to configure and use supervisor to keep up and running Scout's queues?

Level 58

To configure Supervisor to keep Scout's queues running, you need to create a Supervisor configuration file that will manage the Laravel queue worker. Here’s a step-by-step guide to achieve this:

Install Supervisor: Since you mentioned you have already installed Supervisor, we can skip this step. For others, you can install Supervisor using the following command:
```
sudo apt-get install supervisor
```
Create Supervisor Configuration File: Create a new configuration file for your Laravel queue worker. This file is typically placed in /etc/supervisor/conf.d/. For Docker, you might place it in your Docker configuration directory.

Create a file named laravel-worker.conf:
```
sudo nano /etc/supervisor/conf.d/laravel-worker.conf
```
Add Configuration for Laravel Queue Worker: Add the following configuration to the laravel-worker.conf file. This configuration will tell Supervisor to manage the Laravel queue worker process.
```
[program:laravel-worker]
process_name=%(program_name)s_%(process_num)02d
command=php /path/to/your/project/artisan queue:work redis --sleep=3 --tries=3 --timeout=90
autostart=true
autorestart=true
user=your-username
numprocs=1
redirect_stderr=true
stdout_logfile=/path/to/your/project/storage/logs/worker.log
```
Replace /path/to/your/project with the actual path to your Laravel project and your-username with the user that should run the worker.
Update Supervisor Configuration: After creating the configuration file, you need to update Supervisor to read the new configuration.
```
sudo supervisorctl reread
sudo supervisorctl update
```
Start the Laravel Worker: Start the Laravel worker process using Supervisor.
```
sudo supervisorctl start laravel-worker:*
```
Verify the Worker is Running: You can verify that the worker is running by checking the Supervisor status.
```
sudo supervisorctl status
```
You should see an entry for laravel-worker with a status of RUNNING.

Docker Considerations

If you are using Docker, you need to ensure that Supervisor is installed and configured within your Docker container. You can add Supervisor to your Dockerfile and copy the configuration file into the container.

Here’s an example Dockerfile snippet:

# Install Supervisor
RUN apt-get update && apt-get install -y supervisor

# Copy Supervisor configuration
COPY ./docker/laravel-worker.conf /etc/supervisor/conf.d/laravel-worker.conf

# Add Supervisor to the entrypoint
CMD ["/usr/bin/supervisord"]

Make sure to adjust the paths and commands according to your Docker setup.

By following these steps, you should be able to configure Supervisor to keep your Scout's queues running, both in local development and in production.
