 The operator provides reference end-to-end (e2e) tests to
 ensure various infrastructure parts work smoothly together. The test code is available at `e2e/tests`.
-The special `registry.opensource.zalan.do/acid/postgres-operator-e2e-tests-runner` image is used to run the tests. The container mounts the local `e2e/tests` directory at runtime, so whatever you modify in your local copy of the tests will be executed by a test runner. By maintaining a separate test runner image we avoid the need to re-build the e2e test image on every build.
