3.7.5¶
Caution
Upstream Kubernetes has removed the in-tree AWS cloud provider. Kubernetes 1.27.4, which is the version that is configured to MKE 3.7.0, does not support the AWS in-tree cloud provider. As such, if your MKE cluster is using the AWS in-tree cloud provider, you must upgrade to MKE 3.7.12 or later, as these versions support a transition pathway to an alternative external AWS cloud provider.
If you attempt to upgrade a cluster that uses AWS in-tree cloud provider to MKE 3.7.5, the upgrade will fail and you will receive the following error message:
Your MKE cluster is currently using the AWS in-tree cloud provider, which
Kubernetes no longer supports. Please defer upgrading to MKE 3.7 until a
version that supports migration to an alternative external AWS cloud
provider is released.
