Amazon EKS now supports multiple external OIDC identity providers per cluster

Amazon EKS now allows up to 10 external OpenID Connect (OIDC) identity providers per cluster. This enables organizations to associate different identity providers for various user groups such as employees, contractors, and CI/CD systems directly with their cluster, eliminating the need to consolidate users into a single provider or run an intermediary broker. Each provider is configured and managed independently, allowing each group to authenticate through its own provider and identity mapping. Existing IAM authentication continues to work alongside all configured providers. Providers can be added using the AWS Management Console or the AssociateIdentityProviderConfig API via the AWS CLI and SDKs. This capability is available at no extra cost in all AWS Regions where Amazon EKS is offered.

Why it matters

This update affects Kubernetes users who need to integrate multiple identity providers with their clusters. It provides greater flexibility in authentication methods for Amazon EKS clusters.
