Rancher Kubernetes Engine (RKE/RKE1) reached end of life on July 31, 2025 and is no longer supported. RKE1 is superseded by RKE2. Rancher 2.12.0 and later do not support provisioning or managing downstream RKE1 clusters. Replatform your RKE1 clusters to RKE2 to keep receiving support and security updates, following the migration guidance in our Knowledgebase. For lightweight and edge use cases, see K3s.
