Assume Role - CI/CD Glossary Definition
Assuming a role exchanges a trusted identity for temporary credentials scoped to that role.
Assume role is the action of an identity requesting temporary credentials for an IAM role it is trusted to use, receiving short-lived tokens scoped to that role.
Role assumption underpins keyless cloud access in CI/CD, replacing static keys with on-demand, expiring credentials.
In CI/CD
A pipeline calls the cloud STS to assume a deploy role, receiving credentials that expire in minutes to hours, limiting exposure.
