That method does not use docker. You must use docker to have a supported install of Discourse. As a benefit the docker install is much simpler to install and upgrade.
Take a look at these instructions: [discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub](https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md)
The process of getting Docker installed on CentOS might differ, but once you get past that part it should be pretty smooth sailing using those instructions.

Might be time to ask Digital Ocean to upgrade their documentation…
