Racer Controller

The Racer controller keeps track of Racer nodes and named caches in Kubernetes.

ClusterCache

A ClusterCache gives a Racer cache a name. It applies to the whole cluster, not a single namespace, and has no spec fields to configure.

apiVersion: racer.unbounded-cloud.io/v1alpha1
kind: ClusterCache
metadata:
  name: images

Use a lowercase DNS name, such as images or team.images. Names can be up to 82 characters long, with at most 63 characters in each dot-separated part.

List caches with:

kubectl get clustercaches

Applications access a cache through its client socket at /run/racer/<name>/client/socket. Pod volume mounts control access; creating a ClusterCache does not grant every Pod access to it.

Deleting and recreating a ClusterCache creates a new cache identity, even if you reuse the name.
