CRUD Basics — IP Addresses

This notebook demonstrates listing, adding, updating, and deleting IP addresses.

Install

Mix.install([
  {:mikrotik_api, path: ".."}
])

Setup

alias MikrotikApi.Auth
require Logger

auth = Auth.new(
  username: System.get_env("MT_USER"),
  password: System.get_env("MT_PASS"),
  verify: :verify_none
)

ip = System.get_env("MT_IP") || "192.0.2.1"

List addresses

case MikrotikApi.ip_address_list(auth, ip, scheme: :http) do
  {:ok, addrs} -> Logger.info("listed addresses: #{length(addrs)}")
  {:error, err} -> Logger.error("list failed: #{inspect(err)}")
end

Ensure address exists

attrs = %{"address" => "192.168.88.2/24", "interface" => "bridge"}
case MikrotikApi.ip_address_ensure(auth, ip, attrs, scheme: :http) do
  {:ok, addr} -> Logger.info("address present: #{addr}")
  {:error, err} -> Logger.error("ensure failed: #{inspect(err)}")
end

Update and delete by id

with {:ok, list} <- MikrotikApi.ip_address_list(auth, ip, scheme: :http),
     [%{".id" => id} | _] <- list do
  _ = MikrotikApi.ip_address_update(auth, ip, id, %{"disabled" => "no"}, scheme: :http)
  _ = MikrotikApi.ip_address_delete(auth, ip, id, scheme: :http)
  :ok
else
  _ -> Logger.info("no addresses to update/delete")
end
