Verk does not saves the queues that were started dynamically. The initial configuration should have them or when Verk starts, add the queues back again dynamically.
One common use case is to start a supervision tree with the Verk.Supervisor
then a process that adds the dynamic queues when it starts. So if the supervision tree restarts it will guarantee that the queues were added. I can add more information and examples around this if needed.

I would be very grateful to you)
from verk.
You could for example have a supervisor that has the following supervision tree:
tree = [supervisor(Verk.Supervisor, []), worker(QueuesLoader, [])]
opts = [name: MySupervisor, strategy: :rest_for_one]
Supervisor.start_link(tree, opts)
The QueuesLoader
can be a GenServer
that looks like this:
defmodule QueuesLoader do
use GenServer
require Logger
@doc false
def start_link do
GenServer.start_link(__MODULE__, [], name: __MODULE__)
end
@doc false
def init(_args) do
for queues <- MyQueues.all do
Verk.add_queue(...)
end
{ :ok, nil }
end
end
Notice that this supervisor is a rest_for_one
so that if Verk.Supervisor
crashes, it will restart the QueuesLoader
worker as it's defined after the Verk.Supervisor
.
