How to force application version on AWS Elastic Beanstalk
I've realised that the problem was that Elastic Beanstalk, for some reasons, kept the unsuccessfully deployed versions under .elasticbeanstalk. The solution, at least in my case, was to remove those temporal (or whatever you call them) versions of the application.
Maybe the problem is this:
AWS Elastic Beanstalk Docker Does not support Multi-Stage Build
If yes, I solved using an unamed stage for the multi-stage Dockerfile. Chek that link for the solution. However next time I suggest you to post the last-100-rows of logs. The problem can be not clear watching Events log.
