SemanticVersion: 2.1.9
SourceCodeUrl: https://github.com/aws-samples/cloudfront-authorization-at-edge
Parameters:
EmailAddress:
Type: String
Description: The email address of the user that will be created in the Cognito User Pool. Leave empty to skip user creation.
Default: ""
RedirectPathSignIn:
Type: String
Description: The URL path that should handle the redirect from Cognito after sign-in

If you provide those domain names now (comma-separated) the necessary Cognito configuration will already be done for you (unless you're bring your own User Pool from a different AWS account).
Alternatively, update the Cognito configuration yourself after deployment: add sign in and sign out URLs for your custom domains to the user pool app client settings.
Default: ""
CookieSettings:
Type: String
Description: >
The settings for the cookies holding e.g. the JWTs. To be provided as a JSON object, mapping cookie type to setting.
Provide the setting for the particular cookie type as a string, e.g. "Path=/; Secure; HttpOnly; Max-Age=1800; SameSite=Lax".
If left to null, a default setting will be used that should be suitable given the value of "EnableSPAMode" parameter.

Default: "true"
AllowedValues:
- "true"
- "false"
CreateCloudFrontDistribution:
Type: String
Description: >
Set to 'false' to skip the creation of a CloudFront distribution and associated resources, such as the private S3 bucket and the sample React app.
This may be of use to you, if you just want to create the Lambda@Edge functions to use with your own CloudFront distribution.
Default: "true"
AllowedValues:
- "true"
- "false"
CookieCompatibility:
Type: String
Description: >
Specify whether naming of cookies should be compatible with AWS Amplify (default) or Amazon Elasticsearch Service. In case of the latter, turn off SPA mode too: set parameter EnableSPAMode to false

UserPoolArn:
Type: String
Description: "Specify the ARN of an existing user pool to use that one instead of creating a new one. If specified, then UserPoolClientId must also be specified. Also, the User Pool should have a domain configured"
Default: ""
UserPoolAuthDomain:
Type: String
Description: >
The auth domain of the existing User Pool, whose ARN you specified as UserPoolArn, e.g. "my-domain.auth.<region>.amazoncognito.com".
If you don't provide this value, it will be looked up for you automatically. This automatic lookup only works if the pre-existing User Pool is in the same AWS account as this stack,
so if it's not, make sure to explictly specify the UserPoolAuthDomain.
Default: ""
UserPoolClientId:
Type: String
Description: >
Specify the ID of an existing user pool client to use that one instead of creating a new one. If specified, then UserPoolArn must also be specified.

Default: ""
UserPoolClientSecret:
Type: String
Description: >
The client secret of the existing User Pool Client, whose ClientId you specified as UserPoolClientId.
If you don't provide this value, it will be looked up for you automatically. This automatic lookup only works if the pre-existing User Pool Client is in the same AWS account as this stack,
so if it's not, make sure to explictly specify the UserPoolClientSecret.
Default: ""
UserPoolGroupName:
Type: String
Description: >
Specify a group that users have to be part of to view the private site. Use this to further protect your private site, in case you don't want every user in the User Pool to have access.

If the UserPoolGroup is created and the default user is also created (when you specify EmailAddress), that user will also be added to the group.
Default: ""
Version:
Type: String
Description: "Changing this parameter after initial deployment forces redeployment of Lambda@Edge functions"

- "error"
- "debug"
