NDB Operator Release Notes
NDB Operator requires a Kubernetes cluster of version 1.19.0 or greater. Older versions of Kubernetes are not supported; NDB Operator may not work as expected with these, if at all.
NDB Operator works with MySQL NDB Cluster 8.0.26 and later. Earlier releases of NDB Cluster are not supported.
For additional requirements for building NDB Operator from source, see Section 2.5, “Building an NDB Operator Image from Source”.
