- OIDC issuer discovery for Kubernetes service accounts
"The new integration, which is what this blog post is about, wires OIDC in the opposite direction; the Service Account Issuer Discovery feature enables the federation of Kubernetes service account tokens issued by a cluster (the identity provider) with external systems (relying parties) based on the OIDC Discovery Spec. Projected Service Account Tokens are required for this feature to be enabled."
