Updates a trust anchor. You establish trust between IAM Roles Anywhere and your certificate authority (CA) by configuring a trust anchor. You can define a trust anchor as a reference to an Private Certificate Authority (Private CA) or by uploading a CA certificate. Your Amazon Web Services workloads can authenticate with the trust anchor using certificates issued by the CA in exchange for temporary Amazon Web Services credentials.

Required permissions: rolesanywhere:UpdateTrustAnchor.
