Lambda Function URLs support

lambroll can deploy Lambda function URLs.

lambroll deploy --function-url=function_url.json deploys a function URL after the function deploied.

When you want to deploy a public (without authentication) function URL, function_url.json is shown below.

{
  "Config": {
    "AuthType": "NONE"
  }
}

When you want to deploy a private (requires AWS IAM authentication) function URL, function_url.json is shown below.

{
  "Config": {
    "AuthType": "AWS_IAM"
  },
  "Permissions": [
    {
      "Principal": "0123456789012"
    },
    {
      "PrincipalOrgID": "o-123456789",
      "Principal": "*"
    }
  ]
}

• Config maps to CreateFunctionUrlConfigInput in AWS SDK Go v2.
  • Config.AuthType must be AWS_IAM or NONE.
  • Config.Qualifer is optional.
• Permissions is optional.
  • If Permissions is not defined and AuthType is NONE, Principal is set to * automatically.
  • When AuthType is AWS_IAM, you must define Permissions to specify allowed principals.
  • Each elements of Permissons maps to AddPermissionInput in AWS SDK Go v2.
• function_url.jsonnet is also supported like function.jsonnet.
