Hello friend!

This is a great question. The honest truth here is that the sky is the limit. You can automate things in any way that you prefer, or in any way that may be most relevant to the work that you do.

For myself, I automate a lot of tasks by writing bash scripts. Here’s an example of my most recent one: https://gist.github.com/mxroute/93d0e6e19e6ea8c8f05d743a2ef4b505

A lot of others use automation systems like Ansible (for example), you can read about that one here:

The key is to look around for what best fits your needs, and then develop it to conform to the logic that you require it to. There is no one correct path here, there is only what works best and most consistently for your needs.

Kind Regards,
Jarland
