LXD Compute least used member

Update cache

We need to update the cache with the key :self because that’s where the credential for uplink’s lxd is stored.

cert = File.read!(Path.expand("~/.config/lxc/client.crt"))
key = File.read!(Path.expand("~/.config/lxc/client.key"))

credential = %{
  "endpoint" => "https://198.19.249.83:8443",
  "certificate" => cert,
  "private_key" => key
}

Uplink.Cache.put(:self, %{"credential" => credential})

Query instances

alias Uplink.Clients.LXD

frequency =
  LXD.list_instances()
  |> Enum.frequencies_by(fn i -> i.location end)
  |> IO.inspect()

LXD.list_cluster_members()
|> Enum.min_by(fn m -> frequency[m.server_name] || 0 end)
