- The CA cert will end up in the end user's kubeconfig on their client machine, so if it changes they would need to fetch the new one and update their kubeconfig. Therefore, we should avoid changing it as much as possible. - Now the controller writes the CA to a different Secret. It writes both the cert and the key so it can reuse them to create more TLS certificates in the future. - For now, it only needs to make more TLS certificates if the old TLS cert Secret gets deleted or updated to be invalid. This allows for manual rotation of the TLS certs by simply deleting the Secret. In the future, we may want to implement some kind of auto rotation. - For now, rotation of both the CA and TLS certs will also happen if you manually delete the CA Secret. However, this would cause the end users to immediately need to get the new CA into their kubeconfig, so this is not as elegant as a normal rotation flow where you would have a window of time where you have more than one CA. |

Overview
Pinniped provides identity services to Kubernetes.
Pinniped allows cluster administrators to easily plug in external identity providers (IDPs) into Kubernetes clusters. This is achieved via a uniform install procedure across all types and origins of Kubernetes clusters, declarative configuration via Kubernetes APIs, enterprise-grade integrations with IDPs, and distribution-specific integration strategies.
Example use cases
- Your team uses a large enterprise IDP, and has many clusters that they
manage. Pinniped provides:
- Seamless and robust integration with the IDP
- Easy installation across clusters of any type and origin
- A simplified login flow across all clusters
- Your team shares a single cluster. Pinniped provides:
- Simple configuration to integrate an IDP
- Individual, revocable identities
Architecture
The Pinniped Supervisor component offers identity federation to enable a user to access multiple clusters with a single daily login to their external IDP. The Pinniped Supervisor supports various external IDP types.
The Pinniped Concierge component offers credential exchange to enable a user to exchange an external credential for a short-lived, cluster-specific credential. Pinniped supports various authentication methods and implements different integration strategies for various Kubernetes distributions to make authentication possible.
The Pinniped Concierge can be configured to hook into the Pinniped Supervisor's federated credentials, or it can authenticate users directly via external IDP credentials.
To learn more, see architecture.
