This site is running the Ghost Blog platform and at this time updating to a new version takes a little more than a click of a button. The steps for upgrading to a new version of ghost are here: Update Ghost
This is where Ansible comes in and turns the update process into a single command line instruction.
If you don't have ansible installed on your machine you can do so by following their guide. Install Ansible
Here is the playbook I put together to update this blog in a single command with:
$ ansible-playbook update-ghost.yml --ask-become-pass
The update-ghost.yml file contains this:
