Usage - ./eksctl-anywhere exp validate -f <yaml config file>

Output - valid config example:

✅ Validate docker executable
✅ Validate cluster
✅ Validate kubeconfig path
✅ Validate supported provider
✅ Validate certificate for registry mirror
✅ Create preflight validations pass
✅ Connected to server
✅ Authenticated to vSphere
✅ Datacenter validated
✅ Network validated
✅ Datastore validated
✅ Folder validated
✅ Resource pool validated
✅ Control plane and Workload templates validated
Provided control plane sshAuthorizedKey is not set or is empty, auto-generating new key pair...
Private key saved to tmpValidate1230314345/eks-a-id_rsa. Use 'ssh -i tmpValidate1230314345/eks-a-id_rsa <username>@<Node-IP-Address>' to login to your cluster node
✅ Vsphere Provider setup is valid

Output - invalid config example:

✅ Validate docker executable
❌ Validation failed	{"validation": "validate cluster", "error": "failed to validate cluster config name:  is not a valid cluster name, cluster names must start with lowercase/uppercase letters and can include numbers and dashes. For instance 'testCluster-123' is a valid name but '123testCluster' is not. ", "remediation": ""}
Error: validations failed

I haven't reviewed this in full but great work!

Do we think its necessary to output so much information? I suspect consumers don't really care that a specific portion of validation succeeded - that feels more like a debug level of logging. I care whether or not the invocation I made makes sense and I can get that from a single line (ideally) saying "Configuration valid".
