Demo for Kubernetes TokenRequest API

This repo contains example deployment manifest and basic example services that use the TokenRequest and TokenReview APIs. This is a companion to the blog post here go-client was intentionally not used to make building the demo services as easy as possible and not required any dependencies.

Communication flow

  1. Container makes request for a bound service account token via TokenRequest API. In the demo I am using volume projection to handle the fetching of the token on my behalf which is not pictured
  2. API returns a token
  3. token-client Pod makes service to service call to the token-server Pod
  4. token-server Pod validates auth token in http request against the TokenReview API
  5. API responds with validation data about the request token.
  6. If token is valid token-server responds to token-client with request payload.
You can’t perform that action at this time.
