v0.4.0

⚠️ This contains a couple of breaking changes in how the ValkeyCluster spec is defined.

Notably updates below. A big thank you to the contributors in this release! 🎉

Breaking

New spec.scheduling API

• #301
• #310

We have moved these fields from the spec:

spec:
  affinity:
  tolerations:
  topologySpreadConstraints:
  nodeSelector:
  priorityClassName:

They are now located under the spec.scheduling field:

spec:
  scheduling:
    affinity:
    tolerations:
    topologySpreadConstraints:
    nodeSelector:
    priorityClassName:

We have also introduced first-class support for node spread topologies:

spec:
  scheduling:
    node:
      spread:
        shard:
          mode: Disabled
        primaries:
          mode: Disabled
        pods:
          mode: Disabled

If you were previously using this configuration to prevent pods in a shard colocating on the same node:

spec:
  topologySpreadConstraints:
  - maxSkew: 1
    topologyKey: kubernetes.io/hostname
    whenUnsatisfiable: DoNotSchedule

Then you will want to use this instead:

spec:
  scheduling:
    node:
      spread:
        shard:
          mode: Required

This now uses a pod anti affinity under the hood instead of a topology spread constraint. Switching to this prevents a conflict in constraints should another be defined against the topology key used for spreading on hosts, against a whenUnsatisfiable condition.

See the Scheduling docs for more info:

podDisruptionBudget refactor

• #308

spec.podDisruptionBudget is no longer a string but now a struct.

spec.podDisruptionBudget: Managed is now the equivalent of:

spec:
  podDisruptionBudget:
    mode: Cluster

spec.podDisruptionBudget: Disabled is now the equivalent of:

spec:
  podDisruptionBudget:
    mode: Disabled

Added

• priorityClassName to ValkeyCluster.spec
• terminationGracePeriodSeconds to ValkeyCluster.spec
• You can now pull in valkey-operator as a go module via go get github.com/valkey-io/valkey-operator

Fixed

• Resharding via atomic slot migration now works again
