Docker image is not up-to-date

Firstly, thanks a lot for this great project. 
I noticed that docker image of keycloak-config (https://hub.docker.com/layers/alvearie/keycloak-config/latest/images/sha256-995facb58a7d21a5ac0d8c17d80edf1ec2c6f11d6dd03cf32278dad2ab219b90?context=explore) is not up-to-date. For example, via docker image, I can not create a client with service accounts enabled but it works when I use master branch.
