Mattermost Latest Image

I was successfully able to deploy version 3 of mattermost on a kubernetes cluster using the mattermost/mattermost-prod-app:3 image, however I am running into some problems when attempting to use any newer image. I was wondering if anyone could give me any insight to why this would be occurring or alternatives to deploy the latest image of mattermost using a kubernetes cluster.

I would look at https://github.com/mattermost/mattermost-kubernetes
