YAML Anchors and References

This is a post to help me remind how YAML Anchors and References work.

What?

In YAML you can make an Anchor:

- first_name: &me Michael

Now the Anchor me contains Michael. To refer to it, do something like this:

- first_name: &me Michael
  give_name: *me

The value for given_name has been set to Michael.

You can also anchor to a whole list item:

people:
  - person: &me
    name: Michael
    family_name: Buluma

No you may refer to the me anchor:

access:
  - person: *me

Now Michael has access.

Good to prevent dry.
