When checking the docker logs for the web backend container it can be seen starting and communicating with mongo container which starts first but then ultimately registers a failure when deploying a particular vertical as follows:-
2020-11-19 15:41:19,655 [main] INFO o.e.j.s.h.C.nlweb_git_manager_deployment_1_1_6_war - ----- DEPLOYING VERTICLES -----
2020-11-19 15:41:19,799 [main] WARN o.e.j.s.h.C.nlweb_git_manager_deployment_1_1_6_war - ----- DEPLOYING VERTICLES FAILURE -----
It then shuts all services down and exits
