Cannot set a property of cognito userpool client via cloudformation

Question

I am trying to run congnito via cloudformation and everything works but there is section in cognito as follows:

As you see there is section \"Enable identity pr

Answer 1

As other answer suggest, this can't be done in CloudFormation natively as of yet. However, as ASR answer advises it is possible to do so through CloudFormation custom resource.

My employer has open sourced its collection of custom resources, including CognitoUserPool and CognitoDomainName (which is also not supported in CloudFormation). Custom resources source code can be found on github

Below are manual directions on setting this up - you can always automate things further by placing Custom Resource backing Lambda in CloudFormation as well.

All commands below are for Mac. You may need to modify base64 flags for other platforms

1. Create IAM Role For Lambda

aws iam create-role --role-name LambdaRoleCognito --assume-role-policy-document '{
      "Version": "2012-10-17",
      "Statement": [
      {
          "Effect": "Allow",
          "Principal": {
              "Service": "lambda.amazonaws.com"
          },
          "Action": "sts:AssumeRole"
      }
  ]
  }'
aws iam attach-role-policy --role-name LambdaRoleCognito \
  --policy-arn  arn:aws:iam::aws:policy/CloudWatchLogsFullAccess

aws iam attach-role-policy --role-name LambdaRoleCognito \
  --policy-arn  arn:aws:iam::aws:policy/AmazonCognitoPowerUser

2. Download lambda source code, upload to your local bucket, and create lambda

wget https://github.com/base2Services/cloudformation-custom-resources-nodejs/releases/download/1.0.0/ccr-nodejs-1.0.0.zip
account_id=$(aws sts get-caller-identity --query Account --output text)
aws s3 mb s3://${account_id}.cfncustomres.source
aws s3 cp ccr-nodejs-1.0.0.zip s3://${account_id}.cfncustomres.source/ccr-nodejs-1.0.0.zip

aws lambda create-function --function-name CfnCrCognitUPC --runtime nodejs6.10 \
    --role arn:aws:iam::${account_id}:role/LambdaRoleCognito  \
    --timeout 30 \
    --memory-size 512 \
    --code S3Bucket=${account_id}.cfncustomres.source,S3Key=ccr-nodejs-1.0.0.zip \
    --handler cognito-user-pool-client/index.handler

3. Optional Test lambda by invoking with test payload

aws lambda invoke --function-name CfnCrCognitUPC --payload '{
  "StackId": "arn:aws:cloudformation:us-west-2:EXAMPLE/stack-name/guid",
  "ResponseURL": "http://pre-signed-S3-url-for-response",
  "ResourceProperties": {
    "ClientName": "MyCCRCreatedUP",
    "SupportedIdentityProviders": [
      "COGNITO"
    ],
    "UserPoolId":"!! REPLACE WITH YOUR USER POOL ID !!"
  },
  "RequestType": "Create",
  "ResourceType": "Custom::TestResource",
  "RequestId": "unique id for this create request",
  "LogicalResourceId": "MyTestResource"
}' --log-type Tail --invocation-type RequestResponse output.txt --query LogResult --output text | base64 -D

4. Create custom resource in CloudFormation template

For list of all supported properties checkout custom resource JSON schema

Resources:
  MyPoolApplication:
    Type: Custom::CognitoUserPool
    Properties:
      ServiceToken: arn:aws:lambda:<>:<>:function:CfnCrCognitUPC
      ClientName: ApplicationClientNameHere
      UserPoolId: 
        Ref: UserPool
      SupportedIdentityProviders:
        - COGNITO
      .... other support properties ....
