Deploying Laravel with EnvoyJanuary 23, 2015
On a recent project we moved a site from a single server to a series of AWS EC2 instances provisioned with Laravel Forge. With this change we needed to re-think the way we did deployments as they now had to be applied to multiple servers, and we wanted to do it easily and fast. With that in mind we decided to take a look at Envoy, Laravel's task runner.
Here are some excepts from our
envoy.blade.php file, which might be useful to someone else who is considering deployment through Envoy. I've added a little bit of information to each Envoy task to explain what it is and why we use it.
This is the primary deployment task - it deploys the latest code from the
master branch to our two web instances and our worker (queues and crons). We run
composer install as well to get any new dependencies but opt out of development dependencies (not necessary) and use the
--prefer-dist flag to get distribution copies of the dependencies as they should download faster. We don't use parallel deployment in case something goes wrong during deployment so we still have other servers going.
@task('production:deploy', ['on' => ['web1', 'web2', 'worker1']]) cd default php artisan down git pull origin master --force composer install --no-dev --prefer-dist php artisan up @endtask
Just utility tasks to turn the application on and off for whatever reason we might need.
@task('production:up', ['on' => ['web1', 'web2']]) cd default php artisan up @endtask @task('production:down', ['on' => ['web1', 'web2']]) cd default php artisan down @endtask
Migrates the database when necessary. We don't do this in the
production:deploy method just for the peace of mind of having a little bit more control over the database. Furthermore it goes through the worker instance instead of one of the web instances and it also uses the
--force flag so that it doesn't ask "are you sure you want to migrate in production?". So only use this if you're sure you want to migrate in production.
@task('production:migrate', ['on' => 'worker1']) cd default php artisan migrate --force @endtask
In case you stuff it up.
@task('production:migrate:rollback', ['on' => 'worker1']) cd default php artisan migrate:rollback --force @endtask
