assumeRolePolicyDocument

The trust relationship policy document that grants an entity permission to assume the role.

In IAM, you must provide a JSON policy that has been converted to a string. However, for CloudFormation templates formatted in YAML, you can provide the policy in JSON or YAML format. CloudFormation always converts a YAML policy to JSON format before submitting it to IAM.

The regex pattern used to validate this parameter is a string of characters consisting of the following:

• Any printable ASCII character ranging from the space character (\u0020) through the end of the ASCII character range

• The printable characters in the Basic Latin and Latin-1 Supplement character set (through \u00FF)

• The special characters tab (\u0009), line feed (\u000A), and carriage return (\u000D)

Upon success, the response includes the same trust policy in JSON format.
