policyDocument

An endpoint policy, which controls access to the service from the VPC. The default endpoint policy allows full access to the service. Endpoint policies are supported only for gateway and interface endpoints. For CloudFormation templates in YAML, you can provide the policy in JSON or YAML format. For example, if you have a JSON policy, you can convert it to YAML before including it in the YAML template, and CFNlong converts the policy to JSON format before calling the API actions for privatelink. Alternatively, you can include the JSON directly in the YAML, as shown in the following `Properties` section: `Properties: VpcEndpointType: 'Interface' ServiceName: !Sub 'com.amazonaws.${AWS::Region}.logs' PolicyDocument: '{ "Version":"2012-10-17", "Statement": [{ "Effect":"Allow", "Principal":"*", "Action":["logs:Describe*","logs:Get*","logs:List*","logs:FilterLogEvents"], "Resource":"*" }] }'` Search the CloudFormation User Guide for AWS::EC2::VPCEndpoint for more information about the expected schema for this property.
