EKS cluster AWSMachines not created because MachineSet pre-fight check fails

/kind bug

What steps did you take and what happened:
[A clear and concise description of what the bug is.]

Add a MachineDeployment for the EKS cluster deployed by CAPA
No errors in the capa-controller pods

But there is an error for the machineDeployment.

Error messages:
Message: Performing "Scale up" on hold because ControlPlane namespace/cluster-control-plane is provisioning ("ControlPlaneIsStable" preflight failed). The operation will continue after the preflight check(s) pass

After we set the annotation "machineset.cluster.x-k8s.io/skip-preflight-checks: ControlPlaneIsStable", the EC2 machines finally created.

The problem is why the preflight-checks fail? We don't want to add the annotation for every MachineDeployment.
And it seems like a new feature added in Sep by ClusterAPI.

What did you expect to happen:
EC2 machines created without adding the annotation

Anything else you would like to add:
[Miscellaneous information that will assist in solving the issue.]

Environment:

• Cluster-api-provider-aws version: latest
• Kubernetes version: (use kubectl version): 1.29.0
• OS (e.g. from /etc/os-release): ubuntu

Experiencing the same issue but using existing VPC without EKS. Did you find a permanent solution or are you still using the workaround?

Hello,

i am facing the same issue with EKS.

After some research i recognized that the MachineSetPreflightCheck was introduced as an experimental feature in CAPI version 1.5 and has been promoted to beta status in CAPI version 1.9, where it is enabled by default (kubernetes-sigs/cluster-api#11117).

So i'd assume that you are using CAPI >= v1.9.0 (like me) which seems to be not supported by CAPA v2.7.1

An issue for CAPI v1.9.0 was created in Nov 24: #5218

As i am afraid of downgrading to CAPI v1.8.x (which version seems to be supported by CAPA, #5061), i'd like to ask for a CAPA version that supports CAPI >= v1.9.0.

Edit:
Maybe caused by the introduction of v1beta2 structs (kubernetes-sigs/cluster-api#11234)?

Marcel
