## Overview
|
|
|
|
|
|
|
|
|
|
Pinniped provides identity services to Kubernetes.
|
|
|
|
|
|
|
|
|
|
Pinniped allows cluster administrators to easily plugin upstream 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 upstream IDPs, and distribution-specific integration mechanisms.
|
|
|
|
|
|
|
|
|
|
### Use cases
|
|
|
|
|
|
|
|
|
|
* **Your team uses a large enterprise IDP, and has many clusters that they
|
|
|
|
|
manage**; Pinniped provides:
|
|
|
|
|
* seamless and robust integration with the upstream IDP,
|
|
|
|
|
* the ability to be easily installed across clusters of any type and origin,
|
|
|
|
|
* and a simplified login flow across all clusters.
|
|
|
|
|
* **You are on a small team that shares a single cluster**; Pinniped provides:
|
|
|
|
|
* simple configuration for your team's specific needs,
|
|
|
|
|
* and individual, revocable identities.
|
|
|
|
|
|
|
|
|
|
### Architecture
|
|
|
|
|
|
|
|
|
|
Pinniped offers a credential exchange API via a Kubernetes aggregated API where
|
|
|
|
|
a user can exchange an upstream IDP credential for a cluster-specific
|
|
|
|
|
credential. A specific example of this exchange is provided below where:
|
|
|
|
|
* the upstream IDP is a webhook that supports the [Kubernetes TokenReview
|
|
|
|
|
API](https://kubernetes.io/docs/reference/access-authn-authz/authentication/#webhook-token-authentication),
|
|
|
|
|
* the cluster-specific credential is minted using the cluster signing keypair to
|
|
|
|
|
issue short-lived cluster certificates (note: this particular credential minting
|
|
|
|
|
mechanism is temporary until the Kubernetes CSR API provides the ability to set
|
|
|
|
|
a certificate TTL),
|
|
|
|
|
* and the cluster-specific credential is provided to the `kubectl` binary using
|
|
|
|
|
a [Kubernetes client-go credential
|
|
|
|
|
plugin](https://kubernetes.io/docs/reference/access-authn-authz/authentication/#client-go-credential-plugins).
