Enhancement Description

  • One-line enhancement description (can be used as a release note): exposing hashed storage versions via the discovery API
  • Kubernetes Enhancement Proposal:

We propose to expose the hashed storage versions in the discovery API.

Motivation

We intend to use the exposed storage version hash to trigger the storage
version migrator
.

In short, the storage version migrator detects if objects in etcd are stored in
a version different than the configured storage version. If so, the migrator
issues no-op update for the objects to migrate them to the storage version.

The storage version migrator can keep track of the versions the objects are
stored as. However, today the migrator has no way to tell what the expected
storage versions are. Thus we propose to expose this piece of information via
the discovery API.
