@spec valid_path?(Plug.Conn.t(), keyword(), String.t()) :: boolean()

Validates if the request's path matches the expected path for a Kubernetes probe.

This function checks the request_path of an incoming Plug.Conn against a list of allowed paths. If a custom path is provided in the plug_opts argument, it will use that for validation. Otherwise, it falls back to the default_path.

Parameters

• conn - The %Plug.Conn{} struct representing the incoming request.
• plug_opts - A keyword list of options passed to the probe plug, which may contain a :path key specifying custom paths.
• default_path - A string representing the default probe path to validate against.

Example

Assuming the default path:

  iex> conn = %Plug.Conn{request_path: "/health/liveness"}
  iex> opts = []
  iex> KubeProbex.Plug.PathValidator.valid_path?(conn, opts, "/health/liveness")
  true

With a customized path:

  iex> conn = %Plug.Conn{request_path: "/custom/liveness"}
  iex> opts = [path: ["/custom/liveness"]]
  iex> KubeProbex.Plug.PathValidator.valid_path?(conn, opts, "/health/liveness")
  true
