The easiest way is to SSH into your server, cd into your app's current directory and run the Rake task. For this, you'll need to make sure you added your SSH keys to the server so you can login.
cd myapp/currentbundle exec rake mytask
The second option is to use the Scripts feature. You can write your script to do the same thing as above.
First, visit https://www.hatchbox.io/scripts/new to create a new script. Make sure it's set to use the
deploy user and paste in the following script, changing your app name and task name.
#!/usr/bin/env bashset -eexport PATH="$HOME/.rbenv/shims:$PATH"cd /home/deploy/myapp/currentbundle exec rake mytask
Then you can click Run to run your script against the server(s) you want.
