Oh nevermind LE does let you have wildcard certs. I'd just need to use DNS-01 for it but that's not too much trouble.
I'll probably do it with a subdomain so I can still use that domain for other random projects.
Need to figure out the certmanager-cloudflare integration for DNS-01

Kind of?
In those scenarios, even with AKS Automatic and GKE co-pilot, people are still deploying certmanager, istio, and other tech that lives in the cluster.
I'm suggesting it's more like Azure Container Apps and cloud run, but with the k8s API and cost benefits.

Why Istio for Forbes according to Raymond Wong?
1. Unified ingress
2. Integrated certificates managed by CertManager
3. Canary
4. mTLS
5. Observability
6. Multi-cluster service mesh
And why Ambient mode?
1. Kubernetes Gateway API
2. No more sidecar
3. No more restarting applications

I am also playing around with my RaspberryPI5-RKE2-Cluster. I use LongHorn for storage (500GB NVME via PCIe-hat) and everything runs fine - except CertManager DNS01/RFC2136 LetsEncrypt WildcardDomain. But MetalLB and Traefik do run very fine. My Domain is a deep-subdomain (3 segments). nice hobby :)

Neat "stealth" attacker persistence mechanisms for vanilla roll your own k8s. But by the time attackers have root level access to swap CAs or sign CSRs you have much bigger problems than this. Good argument for managed AKS, EKS, GCS, or at least cert management control plane like certmanager.
