The OpenEBS addon requires iSCSI to be running on the worker nodes: https://docs.openebs.io/docs/next/prerequisites.html

I already created my cluster. How can I now make sure, that all my worked nodes have this service installed and running? And how do you make sure, that your packages on the worker nodes are up-to-date (basically regularly running apt-get upgrade)?

Not sure if this is the right place for this bug report, because I think this is actually a missing feature in the API, but I can't find a repository for that.

With hcloud server list --output json, I can get a list of my servers in JSON format. This'll provide the server type's disk size as .server_type.disk:

Hi,
I can successfully associate servers with networks.

resource "hcloud_network" "ens10" {
  name = "ens10"
  ip_range = "10.0.0.0/16"
}
resource "hcloud_network_subnet" "ens10" {
  type = "server"
  network_zone = "eu-central"
  ip_range = "10.0.0.0/24"
  network_id = hcloud_network.ens10.id
}

resource "hcloud_server" "node-0" {
  name        = "node-0"
  server_type = "cpx

Is there documentation explaining architecture and how to write new drivers.

Would love to contribute however need to have more information instead of just guessing from the existing code.
