"""
This module implements an Ansible plugin that is triggered at the start of a playbook.

The plugin dynamically generates a tag for each role. Each tag has the same name as its role.
The advantage of this is that it saves you some boilerplate, because you don't have to wrap
all tasks of a role in an additional block and assign a tag to that.
Additionally, it works automatically when you add new roles to your playbook.

Usage is exactly the same as without this plugin:

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

There are three easy to make mistakes in go. I present them here in the way they are often found in the wild, not in the way that is easiest to understand.

All three of these mistakes have been made in Kubernetes code, getting past code review at least once each that I know of.

1. Loop variables are scoped outside the loop.

What do these lines do? Make predictions and then scroll down.

func print(pi *int) { fmt.Println(*pi) }
