+# Default Rails Deploy Script On Hatchbox
+
+I deployed a Rails app to [Hatchbox](https://hatchbox.io) recently. When
+following along in the log during a deploy, I can see most of what is happening
+as part of the deploy. Though it is too verbose to look through every line. I'd
+rather see the contents of the deploy script.
+
+I did quite a bit of digging around while SSH'd into my hatchbox server, but I
+couldn't find if or where that file might be stored.
+
+Instead, there is a [_Help Center_
+article](https://hatchbox.relationkit.io/articles/55-what-is-the-default-rails-deploy-script)
+where Chris Oliver shares what is in the script.
+
+```bash
+bundle install -j $(nproc)
+yarn install
+bundle exec rails assets:precompile
+[[ -n "${CRON}" ]] && bundle exec rails db:migrate
+```
+
+It does a parallelized `bundle install`, then a `yarn install` (make sure your
+project is using `yarn.lock`), Rails asset precompilation, and then if `CRON`
+is set (Cron role is available by checking _Cron_ under _Server
+Responsibilities_ for your Hatchbox server), it will run Rails migrations.
+
+From app settings, the deploy script can be overridden, or pre- and post-deploy
+steps can be added.
