Hi @Dog2puppy,

There are multiple tools for you to use. Let’s break them down a little bit. So first, if you wish to deploy your application more code based, you can use either git/gitlab/svn etc. I’ll recommend going for git.
Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

If you wish to spin up new droplets and control the configuration they have, you can use either Puppet or Ansible. They are considered the best configuration management tools. Puppet is used for bigger systems which will require a lot of droplets and instances while Ansible can be used to install just the required services such as Nginx and MySQL for instance.

I hope this helped,

Regards,
