Behaviour for defining custom container configurations.

Implementing this behaviour provides a clear contract for custom container types, ensuring they expose the required callbacks.

Example

defmodule MyApp.RedisTestContainer do
  @behaviour TestcontainerEx.Container.Behaviour

  @impl true
  def new(opts \\ []) do
    TestcontainerEx.Container.new(Keyword.get(opts, :image, "redis:7-alpine"))
    |> TestcontainerEx.Container.with_exposed_port(6379)
    |> TestcontainerEx.Container.with_waiting_strategies(default_wait_strategies())
  end

  @impl true
  def default_wait_strategies do
    [TestcontainerEx.Wait.port("localhost", 6379, 30_000)]
  end

  @impl true
  def connection_opts(container) do
    [host: TestcontainerEx.Container.Info.host(container), port: TestcontainerEx.get_port(container, 6379)]
  end
end
