connection

Auth 0 Connection component. Auth0 is a third-party service that provides authentication and authorization as a service. It is typically used to to authenticate users.

An Auth0 connection is a bridge between Auth0 and an identity provider (IdP) that allows your application to authenticate users. Auth0 supports many types of connections, including social identity providers such as Google, Facebook, and Twitter, enterprise identity providers such as Microsoft Azure AD, and passwordless authentication methods such as email and SMS.

Usage

Before deploying this component, you need to deploy the auth0/tenant component. This components with authenticate with the Auth0 Terraform provider using the Auth0 tenant's client ID and client secret configured with the auth0/tenant component.

Here's an example snippet for how to use this component.

components:
  terraform:
    auth0/connection:
      vars:

Context Variables

The following variables are defined in the context.tf file of this module and part of the terraform-null-label pattern.

additional_tag_map (map(string)) optional

Additional key-value pairs to add to each map in tags_as_list_of_maps. Not added to tags or id.
This is for some rare cases where resources want additional configuration of tags
and therefore take a list of maps with tag key, value, and additional configuration.

Required: No

Default value: { }

attributes (list(string)) optional

ID element. Additional attributes (e.g. workers or cluster) to add to id,
in the order they appear in the list. New attributes are appended to the

and treated as a single ID element.

Required: No

Default value: [ ]

context (any) optional

Single object for setting entire context at once.
See description of individual variables for details.
Leave string and numeric variables as null to use default value.
Individual variable settings (non-null) override settings in context object,

(Type is any so the map values can later be enhanced to provide additional options.)
format is a Terraform format string to be passed to the format() function.
labels is a list of labels, in order, to pass to format() function.
Label values will be normalized before being passed to format() so they will be
identical to how they appear in id.

Set this to title and set delimiter to "" to yield Pascal Case IDs.
Default value: lower.

Required: No

Default value: null

labels_as_tags (set(string)) optional
