Migration

Migrate K3s Control Planes to Astra

Migrate K3s Control Planes to Astra

  1. Stand up Astra cluster and validate basic etcd API operations.
  2. Point a non-production K3s control-plane at Astra datastore endpoint.
  3. Replay representative workload and observe API/lease/list behavior.
  4. Compare against etcd baseline using the same harness profile.
  5. Promote only after passing workload-specific parity and SLO gates.

For deployment commands and topology layouts, use Deploy Astra + K3s (single node) and Deploy Astra + K3s (cluster).

Validation Priorities

  • Lease lane stability under churn.
  • LIST latency parity under high object cardinality.
  • Resource profile (iowait, disk IOPS) under sustained reconcile loops.

Rollout Guidance

  • Start with canary control-plane environments.
  • Keep explicit rollback path to prior datastore until SLO confidence is established.
