There used to a documentation before but since docs have changed a lot, many useful links and useful content are either missing or at least i can't find them. All i can find is this : https://docs.alfresco.com/content-services/5.2/install/#installing-alfresco-content-services-and-web... which is for 5.2. Also i can't find a docker image for WCMQS.
Haven't used WCMQS for long time now. And can't recall if it was deprecated for later versions. Hope someone else can shed some light on this.
You may try this distribution for ACS 7 and see if you got lucky :
So proabably you will have to build custom images on top of ACS and share images and apply amps/include wars etc.
Or else you will have to install everything manually using distribution package.
