Deploy on cloud VMs

[mrehanabbasi]

Currently, using this playbook to deploy on the cloud like on DigitalOcean droplets or Hetzner servers is impossible. This will allow people who don't have their own hardware to deploy Kubernetes clusters on the cloud.

Expected Behavior

Should easily deploy to a cloud environment like DigitalOcean droplets, Hetzner servers etc.

Current Behavior

It installs k3s, kube-vip, and MetalLB, but you can't access the applications even after using a Traefik IngressRoute.

Context (variables)

Operating system: ubuntu

Hardware: Hetzner server VMs

Variables Used

all.yml

k3s_version: "v1.31.2+k3s1"

Thanks. k3s was designed to not be in the cloud and this is more of a k3s request. That being said you should be able to disable metallb and it should just work. You don't need metallb in the cloud, because each cloud has a cloud load balancer already.

[mrehanabbasi]

Yeah, I was able to get a cloud load balancer running separately using Traefik and k8s annotations.
