Auto restarting Laravel Horizon on code changes

I have been meaning to look into a solution for restarting Laravel Horizon on code changes for a while. Our team uses Docker for our development environment and a container will start with horizon running. However, any code changes would mean we had to restart that container before the changes would load.

That's when I looked into a solution. It turns out it was pretty simple. There is a handy node tool that will monitor files for changes and restart. I have seen it in use for simple nodejs servers. Enter nodemon

We can install it in an Ubuntu container with

apt-get update && apt-get install npm -y && npm install -g nodemon

Now we launch our horizon with the below command

/usr/local/bin/nodemon --exec /usr/local/bin/php artisan horizon -e php

the -e php tells nodemon to monitor all .php files and restart on a change.

How to deploy OAuth keys on Heroku's ephemeral file system

Deploying a Laravel + Passport App on Heroku can cause some issues with OAuth Keys.

You may see this error

Key path "file:///app/storage/oauth-private.key" does not exist or is not readable

The problem is your Public and Private OAuth keys are quite rightly ignored in your .gitignore

I solved this issue by encrypting the keys and storing them in git, with the help of some custom artisan commands, they are now part of my project but you can grab them.

HerokuEncryptKeys.php

HerokuGenerateKey.php

HerokuInstallKey.php

Step 1

Generate OAuth keys ( if you don't already have some )

php artisan passport:keys

Step 2

Generate an encryption key and add the OENCRYPT_KEY env

php artisan heroku:generatekey

add to your local .env and also add it to Heroku's env settings

OENCRYPT_KEY={the output of php artisan heroku:generatekey}

Step 3

Encrypt your OAuth keys and commit to VCS

php artisan heroku:encryptkeys

Commit storage/app/oauth-private.key.encrypted and storage/app/oauth-pubblic.key.encrypted

Step 4

Add post-install-cmd to composer.json

"scripts": {
        ...
        "post-install-cmd": [ "php artisan heroku:installkeys" ]
    }
