StackController

Serves the compose file of every service the booted plugins declared — readable by a human and by the agent. The same discovery the Stack section reads ({@see StackReader::declarations()}), projected whole by {@see ComposeProjection}. Secrets come out as `${NAME}`; the operator supplies them. Nothing is cached: the file is the declarations as they are on this request. When two plugins declare the same service name there is no file to serve — compose keys services by name and one would silently overwrite the other — so the answer is a 409 that names the collision instead ({@see StackReader::conflicts()}).

public function __construct(Milpa\Runtime\Stack\StackReader $source, Milpa\Runtime\Stack\ComposeProjection $projection, Milpa\Admin\I18n\Catalog $catalog):

Parameters

public function compose(Psr\Http\Message\ServerRequestInterface $request): Psr\Http\Message\ResponseInterface

`GET {route}/stack/compose.yml` — the whole stack as a compose file, `text/yaml`, served as a download; `409 text/plain` with one line per colliding service name when there is no honest file.
