cfn-saml-provider

A CloudFormation custom resource provider for adding a SAML identity provider.

Syntax

To create a SAML provider using your AWS CloudFormation template, use a Custom::SAMLProvider resource with reference to the metadata URL:

  SAMLProvider:
    Type: Custom::SAMLProvider
    Properties:
      Name: auth0
      URL: https://auth0.com/mytenant/providerurl
      ServiceToken: !Sub 'arn:${AWS::Partition}:lambda:${AWS::Region}:${AWS::AccountId}:function:cfn-saml-provider'

or with the metadata itself:

  SAMLProvider:
    Type: Custom::SAMLProvider
    Properties:
      Name: auth0
      Metadata: |
        <EntityDescriptor entityID="urn:binxio.auth0.com" xmlns="urn:oasis:names:tc:SAML:2.0:metadata">
                ....
        </EntityDescriptor>
      ServiceToken: !Sub 'arn:${AWS::Partition}:lambda:${AWS::Region}:${AWS::AccountId}:function:cfn-saml-provider'

On completion, it will return the ARN of the SAML Provider.

Deploy the provider

To deploy the provider, type:

aws cloudformation create-stack \
        --capabilities CAPABILITY_IAM \
        --stack-name cfn-saml-provider \
        --template-body file://cloudformation/cfn-saml-provider.json

aws cloudformation wait stack-create-complete  --stack-name cfn-saml-provider

This CloudFormation template will use our pre-packaged provider from 463637877380.dkr.ecr.eu-central-1.amazonaws.com/xebia/cfn-saml-provider:2.0.0.

Demo

To install the simple sample of the SAML provider, type:

aws cloudformation create-stack --stack-name cfn-saml-provider-demo \
        --template-body file://cloudformation/demo-stack.json
aws cloudformation wait stack-create-complete  --stack-name cfn-saml-provider-demo

to validate the result, type:

aws iam list-saml-providers
