Getting an HTTP 407 error, testcontainers unable to auth to docker?

[akosasante]

Using testcontainers-elixir 1.12.0

My test_helper.exs:

Testcontainers.start_link()
ExUnit.start()

Sample test file:

defmodule ContainersTest do
  use ExUnit.Case, async: true

  def setup do
    config = %Testcontainers.Container{image: "redis:5.0.3-alpine"}
    {:ok, container} = Testcontainers.start_container(config)

    {:ok, container: container}
  end

  test "container is running", %{container: container} do
    IO.inspect(container, label: "Container")
    :ok
  end
end

The test exits with the failure ** (EXIT from #PID<0.98.0>) {:error, {:http_error, 407}}

I dug into the source code a bit and this seems to be returned when I run the code:

"Pull failed due to an unauthenticated request. Registry Access Management is enabled, which requires pulls to be authenticated. Please run `docker login`, or contact your administrators if this is unexpected.\n"

I have run docker login first but it doesn't change the outcome. Please advise what else I can do to help debug.

ouch this is something i need to implement support for in testcontainers for elixir, allow automatic authorization towards the registry. I believe docker login saves a token in a file locally, but i need to investigate how java or go does it.
