Usually there is a built job on a Continous Delivery Server like Jenkins that will run composer outside of Capistrano once, but in our case we want to be sure that all our Composer dependencies are being met.

Automate composer update

You can add these lines of code either to your deploy.rb or deploy/dev.rb to install all packages for PHP.

run_locally do
  invoke 'composer:local:run', 'install', '--no-interaction'
end

Clearing OPcache

We want to make sure that our app will be fully reloaded after deployment. In order to get this running we will automatically upload a PHP file and call it. This will empty the OpCache of PHP.

Configuration

In our sample application the document_root is the web folder. That means we have to configure our task accordingly so it uploads the clear cache file to location it can reach with curl.

In our deploy.rb we add the following line:

set :remote_web_root_path, 'web'

Run manually

cap dev php:clear_opcache

Output

00:00 php:clear_opcache
      Uploading /Users/dkd-hayes/.rvm/gems/ruby-2.1.8/gems/dkdeploy-php-7.0.0/lib/capistrano/dkdeploy/../../../vendor/opcache_reset.php 100.0%
      Call URL http://localhost:8877/opcache_reset.php
      Result 200 - OK
      01 rm -f /var/www/faker-app/current/web/opcache_reset.php
    ✔ 01 dkd-hayes@localhost 0.009s

As you can see above, the uploaded file will be removed immediately.

Run automatically

In our deploy.rb we add the following lines:

after 'deploy:finished', 'php:clear_opcache'
