It is more a question than an issue. Containers on dockerhub looks a bit outdated - maybe it is a good idea to make some automated builds on webhooks? Also supporting more specified tags (with php version - I've tried with updating php version to 7.2 but it is quite complicated) would be nice - many projects require 7.2 php version due to object typehinting.

I may help, but don't want to make something which won't be accepted later :)
