app

Auth0 Application 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 application is a client that can request authentication and authorization from an Auth0 server. Auth0 applications can be of different types, such as regular web applications, single-page applications, machine-to-machine applications, and others. Each application has a set of allowed origins, allowed callback URLs, and allowed web origins.

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.

Stack Level: Global

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

important

Be sure that the context ID does not overlap with the context ID of other Auth0 components, such as auth0/tenant. We use this ID to generate the SSM parameter names.

# stacks/catalog/auth0/app.yaml
components:
  terraform:
    auth0/app:
      vars:
        enabled: true
        name: "auth0-app"

        # We can centralize plat-sandbox, plat-dev, and plat-staging all use a "nonprod" Auth0 tenant, which is deployed in plat-staging.
        auth0_tenant_stage_name: "plat-staging"

        # Common client configuration
        grant_types:
          - "authorization_code"
          - "refresh_token"
          - "implicit"
          - "client_credentials"

        # Stage-specific client configuration
        callbacks:
          - "https://auth.acme-dev.com/login/auth0/callback"
        allowed_origins:
          - "https://*.acme-dev.com"
        web_origins:
          - "https://portal.acme-dev.com"
          - "https://auth.acme-dev.com"

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
end of the list. The elements of the list are joined by the delimiter
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,
except for attributes, tags, and additional_tag_map, which are merged.

Required: No

Default value:

{
  "additional_tag_map": {},
  "attributes": [],
  "delimiter": null,
  "descriptor_formats": {},
  "enabled": true,
  "environment": null,
  "id_length_limit": null,

    "unset"
  ],

Default value: null

descriptor_formats (any) optional

Describe additional descriptors to be output in the descriptors output map.
Map of maps. Keys are names of descriptors. Values are maps of the form
\{<br/> format = string<br/> labels = list(string)<br/> \}
(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.
Default is {} (descriptors output will be empty).

Required: No

Default value: { }

enabled (bool) optional

Set to false to prevent the module from creating any resources
Required: No

Default value: null

Required: No

Default value: null

label_value_case (string) optional

Controls the letter case of ID elements (labels) as included in id,
set as tag values, and output by this module individually.
Does not affect values of tags passed in via the tags input.
Possible values: lower, title, upper and none (no transformation).
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

Set of labels (ID elements) to include as tags in the tags output.
Default is to include all labels.
Tags with empty values will not be included in the tags output.
Set to [] to suppress all generated tags.
Notes:
The value of the name tag, if included, will be the id, not the name.
Unlike other null-label inputs, the initial setting of labels_as_tags cannot be
changed in later chained modules. Attempts to change it will be silently ignored.
