Hello,
Due to an unfortunate refactoring which is not covered by any test, Quibble 0.0.36 would fail to find a local_settings.php file. It contains some MediaWiki settings specific to Quibble but the file was not installed.
I have cut a new version 0.0.37 which has the file. Sorry for the inconvenience.
The new containers:
docker-registry.discovery.wmnet/releng/quibble-coverage:0.0.37 docker-registry.discovery.wmnet/releng/quibble-fresnel:0.0.37 docker-registry.discovery.wmnet/releng/quibble-stretch:0.0.37 docker-registry.discovery.wmnet/releng/quibble-stretch-bundle:0.0.37 docker-registry.discovery.wmnet/releng/quibble-stretch-php70:0.0.37 docker-registry.discovery.wmnet/releng/quibble-stretch-php71:0.0.37 docker-registry.discovery.wmnet/releng/quibble-stretch-php72:0.0.37 docker-registry.discovery.wmnet/releng/quibble-stretch-php73:0.0.37
