This documentation is destined for drupal.org. Created first as a gist to make initial comments easier. Rewrites and clarifications welcome. Code samples are simplified for clarity. Perhaps a bit too much?

When talking about extensibility, there are several distinct use cases:

1. Reacting to an action that has already happened.

The reaction can be anything; outputting a message, sending an email, modifying a related object, etc. Examples:

• "A node has been saved"
• "A product has been added to the cart".

# each mapRoles entry maps an IAM role to a username and set of groups
# Each username and group can optionally contain template parameters:
#  1) "{{AccountID}}" is the 12 digit AWS ID.
#  2) "{{SessionName}}" is the role session name, with `@` characters
#     transliterated to `-` characters.
#  3) "{{SessionNameRaw}}" is the role session name, without character
#     transliteration (available in version >= 0.5).
mapRoles:
# statically map arn:aws:iam::000000000000:role/KubernetesAdmin to cluster admin
- roleARN: arn:aws:iam::000000000000:role/KubernetesAdmin
