The main focus of dockware is definitely Shopware 6.
Still we heard your requests about supporting Shopware 5.
So we have decided to do a limited support of Shopware 5 with a few versions (and not every single one).
It works basically the same as with Shopware 6. Only a few things like watchers and so on are either different or not included.
Please see Docker Hub for existing Shopware 5 versions.
