Description

Alpha clusters are not suitable for production workloads. They are intended for early adopters to test new features before they become production-ready. Although they enable all Kubernetes API features, alpha clusters are not covered by the GKE SLA, do not receive security updates, have node auto-upgrade and node auto-repair disabled, cannot be upgraded, and are automatically deleted after 30 days.

Note: Alpha features cannot be disabled. To remediate, a new cluster must be created.

Remediation

1. Go to the Kubernetes Engine.
2. Click CREATE CLUSTER.
3. Configure the cluster as required.
4. Confirm that the Enable Kubernetes alpha features in this cluster checkbox is not selected.
5. Click CREATE.
