@Falco I know you obviously do not provide support for Bitnami docker image, which is why my question was merely regarding the use of redis during assets compilation. I only provided the link to the repo for reference to the source code.
By the way, I know of the Discourse official Standard Installation but it does not answer our needs for an easy and straight-forward docker-compose based deployment, which is why we decided to go with Bitnami image.
