Scylla Operator 1.5

The Scylla team is pleased to announce the release of Scylla Operator 1.5.

Scylla Operator is an open-source project that helps Scylla Open Source and Scylla Enterprise users run Scylla on Kubernetes. The Scylla operator manages Scylla clusters deployed to Kubernetes and automates tasks related to operating a Scylla cluster, like installation, scale out and downscale, as well as rolling upgrades.

Scylla Operator 1.5 improves stability and brings a few features. As with all of our releases, any API changes are backward compatible.

API changes

  • ScyllaCluster now supports specifying image pull secrets to enable using private registries. (#678)
    • To learn more about it use kubectl explain scyllacluster.spec.imagePullSecrets.

Notable Changes

  • ScyllaCluster now allows changing resources, placement and repository. (#763)
  • The operator validation webhooks now chain the error, so you no longer have to iterate “one by one” if your CR contained more than one error. (#695)
  • Operator and webhook server pods are now preferred to be scheduled to a different node (within the same deployment) for better HA. (#700)
  • Scylla manager deployment got a readiness probe to indicate its state better. (#725)
  • Webhook server got a PodDisruptionBudget for better HA when pods are being evicted. #715
